CompTIA SY0-701 Dumps

Comprehensive and Detailed Explanation From Exact Extract:

Static analysis, also known as Static Application Security Testing (SAST), analyzes source code without executing it to identify security weaknesses such as hard-coded passwords, insecure API calls, and improper credential handling. This aligns exactly with the issue described—credentials embedded directly in code.

CompTIA Security+ SY0-701 stresses that secure software development practices must include automated static code analysis tools that scan for credential exposure, insecure dependencies, injection risks, and coding standards violations. Static analysis detects these issues early in the SDLC, long before deployment.

A vulnerability scan (A) examines running systems, not source code. A penetration test (B) actively exploits vulnerabilities but cannot reliably detect embedded secrets. Quality assurance (D) checks functional requirements, not security flaws in code.

Therefore, static analysis is the correct and most effective assessment to prevent reoccurrence of hard-coded credentials in software systems.

"Network segmentation is a security practice that divides a network into smaller, isolated segments to limit access and reduce the attack surface. Firewalls are commonly used to enforce segmentation by creating rules that allow or deny traffic based on source, destination, and port. Tomeet compliance requirements, such as restricting access to internal servers, firewall rules can be configured to block all external traffic while permitting only authorized internal systems to communicate with the segmented servers. This ensures that sensitive resources are isolated from unauthorized access."

An application allow list is a security technique that specifies which applications are permitted to run on a system or a network. An application allow list can block unknown programs from executing by only allowing the execution of programs that are explicitly authorized and verified. An application allow list can prevent malware, unauthorized software, or unwanted applications from running and compromising the security of the system or the network12.

The other options are not the best ways to block unknown programs from executing:

Access control list: This is a security technique that specifies which users or groups are granted or denied access to a resource or an object. An access control list can control the permissions and privileges of users or groups, but it does not directly block unknown programs from executing13.

Host-based firewall: This is a security device that monitors and filters the incoming and outgoing network traffic on a single host or system. A host-based firewall can block or allow networkconnections based on predefined rules, but it does not directly block unknown programs from executing1 .

DLP solution: This is a security system that detects and prevents the unauthorized transmission or leakage of sensitive data. A DLP solution can protect the confidentiality and integrity of data, but it does not directly block unknown programs from executing1 .

The correct answer is C. Password, authentication token, thumbprint. This combination of authentication factors satisfies the manager’s goal of implementing multifactor authentication that uses something you know, something you have, and something you are.

Something you know is a type of authentication factor that relies on the user’s knowledge of a secret or personal information, such as a password, a PIN, or a security question. A password is a common example of something you know that can be used to access a VPN12

Something you have is a type of authentication factor that relies on the user’s possession of a physical object or device, such as a smart card, a token, or a smartphone. An authentication token is a common example of something you have that can be used to generate a one-time password (OTP) or a code that can be used to access a VPN12

Something you are is a type of authentication factor that relies on the user’s biometric characteristics, such as a fingerprint, a face, or an iris. A thumbprint is a common example of something you are that can be used to scan and verify the user’s identity to access a VPN12

Security of architecture is the process of designing and implementing a secure infrastructure that meets the business objectives and requirements. Security of architecture should be considered first when migrating to an off-premises solution, such as cloud computing, because it can help to identify and mitigate the potential risks and challenges associated with the migration, such as data security, compliance, availability, scalability, and performance. Security of architecture is different from security of cloud providers, which is the process of evaluating and selecting a trustworthy and reliable cloud service provider that can meet the security and operational needs of the business. Security of architecture is also different from cost of implementation, which is the amount of money required to migrate and maintain the infrastructure in the cloud. Security of architecture is also different from ability of engineers, which is the level of skill and knowledge of the IT staff who are responsible for the migration and management of the cloud infrastructure. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 3491

Detailed Explanation:A Memorandum of Agreement (MOA) outlines terms of cooperation, including restrictions on sharing intellectual property. A breach indicates the terms of the agreement were violated, compromising confidentiality or usage terms. Reference: CompTIASecurity+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Third-Party Risk Management"​​.

Code signing uses digital signatures to verify software authenticity and integrity, ensuring the code has not been tampered with since it was signed by the developer. It helps detect if malware was introduced after delivery.

Static code analysis (B) inspects code for vulnerabilities during development but does not verify delivered binaries. Input validation (C) protects applications at runtime. Secure storage (A) protects stored data, unrelated to software delivery.

Code signing is an essential security control in Software Development Life Cycle and Supply Chain Security【6:Chapter 7†CompTIA Security+ Study Guide】.

Hardware-level memory encryption is designed to protect the contents of RAM from being read or stolen by an attacker who gains sufficient access (for example, through privileged malware, a hypervisor/host compromise, physical attacks like cold-boot techniques, or other memory-snooping methods). That maps directly to data in use, because “data in use” is the state where data is actively processed and often resides in memory during computation. The Study Guide explicitly defines the three data states and makes the connection to memory for data in use: “Data in use is data that is actively in use by a computer system. This includes the data stored in memory while processing takes place. An attacker with control of the system may be able to read the contents of memory and steal sensitive information.”

By contrast, data at rest focuses on storage media (disk, tape, cloud storage), data in transit focuses on network movement, and data sovereignty concerns jurisdiction/location requirements—none of which are directly addressed by encrypting RAM contents at the hardware level. Since the requirement is specifically “hardware-level memory encryption,” the targeted data state is unambiguously data in use.

Change management procedures provide structured steps to approve, test, document, and deploy software changes, ensuring controlled and auditable version releases that minimize risks and disruptions.

Business continuity planning (A) relates to operational continuity, quantified risk analysis (B) assesses risks quantitatively, and static code analysis (C) finds coding defects but does not control release processes.

Change management is fundamental to software lifecycle governance in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

Tokenization replaces sensitive financial data—such as credit card numbers, account numbers, or customer identifiers—with harmless tokens that retain usability but reveal nothing if leaked. This is widely used in the financial industry, particularly in PCI-DSS-regulated systems.

Hashing (B) is one-way and not reversible, making it unsuitable for financial transactions that need original data retrieved. Salting (C) is used to protect hashed passwords, not to mask financial data. Steganography (D) hides data inside media files but is not used for payment processing.

Security+ SY0-701 identifies tokenization as the preferred method for protecting structured sensitive data while maintaining operational functionality.

Thus, the correct answer is A: Tokenization.

An Intrusion Prevention System (IPS) is designed to automatically block or mitigate malicious network traffic in real time. Unlike an IDS, which only detects threats, an IPS performs inline traffic inspection and takes active action—such as dropping malicious packets, blocking connections, or updating firewall rules. This matches the requirement for an automated system that responds immediately to inbound threats.

Security+ SY0-701 highlights IPS as a preventive control that detects signature-based, anomaly-based, and behavioral threats, including exploits, malware, and command-and-control activity. IPS systems are essential in defending against fast-moving attacks where human response time is too slow.

UEM (A) manages endpoints but does not block inbound network threats.

WAF (C) protects web applications, not the entire network.

VPN (D) provides secure tunnels but does not prevent malicious inbound traffic.

Thus, B: IPS is the best solution for automatic threat blocking.

Host isolation ensures that a device cannot communicate with other systems on the network. Isolation is typically applied through EDR/XDR tools, quarantine mechanisms, or endpoint firewalls. Security+ SY0-701 identifies host isolation as a containment technique used when:

A device is suspected of compromise

Lateral movement must be prevented

Sensitive systems must be protected

A system must be completely cut off except for administrative access

Isolation enforces an immediate block on all inbound and outbound communications, effectively making the device inaccessible to any network-based resource.

Disablement of unused services (A) reduces attack surface but does not isolate the device.

A WAF (B) protects web applications, not device access.

A network IDS (D) only monitors traffic and does not block access.

Thus, C: Host isolation is the correct answer.

Data in transit is data that is moving from one location to another, such as over a network or through the air. Data in transit is vulnerable to interception, modification, or theft by malicious actors. A VPN (virtual private network) is a technology that protects data in transit by creating a secure tunnel between two endpoints and encrypting the data that passes through it2.

Anair-gapped (C)system is completely isolated from unsecured networks (like the internet) and other systems, preventing any form of remote access. This is often used in highly sensitive environments such as military, nuclear, or critical infrastructure systems.

This is mentioned underDomain 3.4: Given a scenario, apply cybersecurity resilience conceptsin theCompTIA Security+ SY0-701 Exam Objectives, specifically under“Isolation (e.g., air-gapped)”.

For extended power failures, the best safeguard is a generator. CompTIA Security+ SY0-701 emphasizes that generators are designed to provide long-term, sustained power, unlike UPS systems, which only supply temporary emergency power.

Generators ensure that critical operations—including data centers, communication systems, and security infrastructure—stay online for hours or days, depending on fuel capacity. This matches the requirement for mitigating “extended” outages.

UPS units (C) protect against short-term outages and provide time for graceful shutdown or generator startup, but cannot support prolonged power consumption. Batteries (B) provide the least protection and run out quickly. Off-site backups (A) do not maintain operational continuity; they simply preserve data.

Disaster recovery and business continuity planning in SY0-701 highlights generators as essential components for maintaining availability, a core principle of the CIA triad. Generators prevent downtime, maintain productivity, and keep essential systems functioning throughout prolonged outages, making D the best answer.

Detailed Explanation:A simulated failover tests the disaster recovery site's ability to handle a full transition of services. This ensures all systems can function as expected during an actual disaster. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Disaster Recovery and Business Continuity Planning"​​.

Detailed Explanation:Quarantining a potentially infected system by placing it into an air-gapped environment physically disconnects it from the network. This prevents the spread of malware while maintaining the integrity of forensic evidence. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Incident Response and Containment"​​.

Full packet capture is a technique that records all network traffic passing through a device, such as a router or firewall. It allows for detailed analysis and investigation of network events, such as SQLi attacks, by providing the complete content and context of the packets. Full packet capture can help identify the source, destination, payload, and timing of an SQLi attack, as well as the impact on the server and database. Logging NetFlow traffic, network traffic sensors, and endpoint and OS-specific security logs can provide some information about network activity, but they do not capture the full content of the packets, which may limit the scope and depth of the investigation. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 372-373

Endpoint detection and response (EDR) is a technology that monitors and analyzes the activity and behavior of endpoints, such as computers, laptops, mobile devices, and servers. EDR can help to detect and prevent malicious software, such as viruses, malware, and Trojans, from infecting the endpoints and spreading across the network. EDR can also provide visibility and response capabilities to contain and remediate threats. EDR is different from IDS, which is a network-based technology that monitors and alerts on network traffic anomalies. EDR is also different from ACL, which is a list of rules that control the access to network resources. EDR is also different from NAC, which is a technology that enforces policies on the network access of devices based on their identity and compliance status. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 2561

The correct answer is Wired because Network Access Control (NAC) platforms are primarily designed to control and secure access to an organization’s wired and wireless network infrastructure, with a strong emphasis on enforcing policies at the point where devices connect to the network. In the context of the Security+ SY0-701 objectives, NAC is a key architectural control used to reduce attack surface by preventing unauthorized, unmanaged, or noncompliant devices from gaining network access.

A NAC solution works by authenticating and evaluating devices before granting them access to network resources. This commonly includes checking device identity, credentials, patch levels, antivirus status, and compliance with security policies. For wired networks, NAC enforces controls at switch ports using technologies such as 802.1X, ensuring that only approved devices can connect to internal networks. This directly protects the wired attack surface by stopping threats like rogue devices, compromised laptops, or unauthorized systems from plugging into an Ethernet port and gaining access.

Option A, Bluetooth, is incorrect because NAC platforms do not directly manage short-range personal area network technologies. Option C, NFC, is also incorrect because NFC is typically used for proximity-based authentication or payments and is outside the scope of NAC enforcement. Option D, SCADA, refers to industrial control systems, which require specialized security controls and are not the primary target of standard enterprise NAC solutions.

The SY0-701 study guide highlights NAC as a preventive and detective control that supports zero trust principles by verifying devices before allowing access. By securing the wired network attack surface, NAC significantly reduces lateral movement opportunities and limits the impact of compromised or unauthorized endpoints following a security incident.

VM escape is a vulnerability where an attacker breaks out of a virtual machine guest environment to access the host hypervisor, gaining control over other guests or the host system itself.

Cross-site scripting (A) and SQL injection (B) are application-layer attacks. Race condition (C) is a timing-related vulnerability.

VM escape is a critical threat in virtualized environments discussed under Threats and Vulnerabilities in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

An external examination (also known as an external audit or external review) is the best method for the Chief Information Security Officer (CISO) to gain an understanding of how the company’s security policies compare to external regulatory requirements. External examinations are conducted by third-party entities that assess an organization’s compliance with laws, regulations, and industry standards.

Penetration tests focus on identifying vulnerabilities, not compliance.

Internal audits assess internal controls but are not impartial or focused on regulatory requirements.

Attestation is a formal declaration but does not involve the actual evaluation of compliance​​​.

Risk identificationis the first step in the risk management process, where potential threats and vulnerabilities are analyzed to understand their impact on an organization. This includesidentifying assets, evaluating threats, and assessing potential vulnerabilities.

Risk mitigation: Reducing risk by implementing controls.

Risk treatment: Determining how to handle identified risks.

Risk monitoring and review: Ongoing evaluation of risk controls.

 A geolocation policy is a policy that restricts or allows access to data or resources based on the geographic location of the user or device. A geolocation policy can be implemented using various methods, such as IP address filtering, GPS tracking, or geofencing. A geolocation policy can help the company’s legal department to prevent unauthorized access to sensitive documents from individuals in high-risk countries12.

The other options are not effective ways to limit access based on location:

Data masking: This is a technique of obscuring or replacing sensitive data with fictitious or anonymized data. Data masking can protect the privacy and confidentiality of data, but it does not prevent access to data based on location3.

Encryption: This is a process of transforming data into an unreadable format using a secret key or algorithm. Encryption can protect the integrity and confidentiality of data, but it does not prevent access to data based on location. Encryption can also be bypassed by attackers who have the decryption key or method4.

Data sovereignty regulation: This is a set of laws or rules that govern the storage, processing, and transfer of data within a specific jurisdiction or country. Data sovereignty regulation can affect the availability and compliance of data, but it does not prevent access to data based on location. Data sovereignty regulation can also vary depending on the country or region.

Jailbreaking is a primary security concern for a company setting up a BYOD (Bring Your Own Device) program. Jailbreaking is the process of removing the manufacturer’s or the carrier’s restrictions on a device, such as a smartphone or a tablet, to gain root access and install unauthorized or custom software. Jailbreaking can compromise the security of the device and the data stored on it, as well as expose it to malware, viruses, or hacking. Jailbreaking can also violate the warranty and the terms of service of the device, and make it incompatible with the company’s security policies and standards. Therefore, a company setting up a BYOD program should prohibit jailbreaking and enforce device compliance and encryption. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 76. CompTIA Security+ SY0-701 Exam Objectives, Domain 2.4, page 11.

An Intrusion Prevention System (IPS) is the most effective addition when an organization already has a firewall but continues to face repeated external attacks. Security+ SY0-701 states that an IPS operates inline and automatically blocks malicious traffic in real time based on signatures, anomaly behavior, or heuristics. Whereas a firewall filters traffic by rules, an IPS detects and prevents deeper-level threats such as exploits, malware, and command-and-control attempts.

A UTM (C) includes IPS features, but it is typically used to replace a firewall with an all-in-one appliance. The question states the organization already has a firewall, so the most efficient addition is a standalone IPS. A SIEM (A) aggregates and analyzes logs but does not block attacks. A load balancer (B) distributes traffic for performance—not security.

Thus, the best item to stop active inbound attacks is D: IPS.

Multi-Factor Authentication (MFA) and patch management are both examples of preventative and technical controls. MFA prevents unauthorized access by requiring multiple forms of verification, and patch management ensures that systems are protected against vulnerabilities by applying updates. Both of these controls are implemented using technical methods, and they work to prevent security incidents before they occur.

Detailed Explanation:

Retention policies dictate how long data must be stored to comply with local and international regulations. Non-compliance can result in legal and financial penalties. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Data Retention and Legal Requirements"​​.

The correct answer is immutability, which is a critical concept in backup security and ransomware resilience as covered in the CompTIA Security+ SY0-701 study guide. Immutability ensures that backup data, once written, cannot be altered, modified, or deleted for a defined period of time. This protection is essential in ransomware recovery scenarios because modern ransomware often attempts to encrypt or delete backups to prevent recovery.

Immutable backups are typically implemented using write-once-read-many (WORM) storage or immutable cloud storage configurations. When immutability is enforced, even administrators or attackers with elevated privileges cannot modify the backup contents during the retention window. As a result, organizations can be confident that their backups remain in a known-good, unaltered state, free from ransomware infection or tampering.

The other options do not provide the same guarantee. Destruction refers to permanently deleting data, which would eliminate backups rather than protect them. Sanitization is the process of securely erasing data from storage media and is unrelated to preserving clean backups. Retention defines how long backups are kept but does not protect them from being modified or encrypted during that period.

From a Security+ SY0-701 perspective, immutability is closely tied to resilience, recovery, and data protection strategies. It supports business continuity by ensuring that organizations can reliably restore systems after an attack. Immutable backups are a cornerstone of modern ransomware defense strategies because they prevent attackers from corrupting recovery data. Therefore, immutability is the best and most effective control to guarantee that backups used for recovery are not infected.

Hashing is used to verify data integrity. By comparing the hash value of the data before and after transmission, it is possible to determine if the data has been altered in transit. If the hash values match, the data has not been modified.

Data classification is the process of assigning labels to data based on its sensitivity and business impact. Different organizations and sectors may have different data classification schemes, but a common one is the following1:

Public: Data that can be freely disclosed to anyone without any harm or risk.

Private: Data that is intended for internal use only and may cause some harm or risk if disclosed.

Confidential: Data that is intended for authorized use only and may cause significant harm or risk if disclosed.

Restricted: Data that is intended for very limited use only and may cause severe harm or risk if disclosed.

In this scenario, the company is developing a critical system for the government and storing project information on a fileshare. This data is likely to be classified as confidential and restricted, because it is not meant for public or private use, and it may cause serious damage to national security or public safety if disclosed. The government may also have specific requirements or regulations for handling such data, such as encryption, access control, and auditing2. References: 1: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 16-17 2: Data Classification Practices: Final Project Description Released

According to the shared responsibility model, the client and the cloud provider have different roles and responsibilities for securing the cloud environment, depending on the service model. In an IaaS (Infrastructure as a Service) model, the cloud provider is responsible for securing the physical infrastructure, such as the servers, storage, and network devices, while the client is responsible for securing the operating systems, applications, and data that run on the cloud infrastructure. Therefore, the client is responsible for securing the company’s database in an IaaS model for a cloud environment, as the database is an application that stores data. The client can use various security controls, such as encryption, access control, backup, and auditing, to protect the database from unauthorized access, modification, or loss. The third-party vendor and the DBA (Database Administrator) are not roles defined by the shared responsibility model, but they may be involved in the implementation or management of the database security. References = CompTIA Security+ SY0-701 Certification Study Guide, page 263-264; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 3.1 - Cloud and Virtualization, 5:00 - 7:40.

A backout plan provides a documented procedure to revert or undo a change if it fails or causes issues, helping to restore the environment quickly and prevent extended downtime. Having a backout plan in place minimizes impact during failed changes.

User notification (A) informs users but does not prevent failures. Change approval (B) and risk analysis (C) occur before the change and cannot fix issues after failure.

Backout planning is a best practice in Change Management covered in Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】

 Capacity planning is the process of determining the resources needed to meet the current and future demands of an organization. Capacity planning can help a company develop a business continuity strategy by estimating how many staff members would be required to sustain the business in the case of a disruption, such as a natural disaster, a cyberattack, or a pandemic. Capacity planning can also help a company optimize the use of its resources, reduce costs, and improve performance. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 4, page 184.

To enhance security for a system running an end-of-life operating system, placing the system in an isolated VLAN is the most effective approach. By isolating the system from the rest of the network, you can limit its exposure to potential threats while maintaining its functionality. This segmentation helps protect the rest of the network from any vulnerabilities in the outdated system.

Installing HIDS (Host-based Intrusion Detection System) can help detect intrusions but won't mitigate the risks posed by an unsupported OS.

Decommissioning may not be feasible if the system is critical.

Encrypting the system's hard drive protects data at rest but doesn't address vulnerabilities from an outdated OS​​​.

A Service Level Agreement (SLA) defines the expectations between service providers and customers, including response times, escalation procedures, and performance metrics. It ensures accountability and measurable service quality.

BPA (Blanket Purchase Agreement) relates to purchasing terms, MOA (Memorandum of Agreement) outlines responsibilities but is less specific on performance, NDA (Non-Disclosure Agreement) covers confidentiality.

SLAs are key in Security Program Management for managing vendor and internal service expectations【6:Chapter 16†CompTIA Security+ Study Guide】.

A honeytoken is a form of deception technology in which a fake asset (such as credentials, files, or database records) is planted in a system or network to detect unauthorized access or malicious activity. The fake password stored in a hidden spreadsheet, with monitoring for access, is a classic example of a honeytoken. It is not an interactive system (like a honeypot or honeynet) but rather a marker or tripwire intended to alert the security team to suspicious behavior. This method helps identify attackers and their methods early in the intrusion process.

Purple is the team that combines both offensive and defensive testing techniques to protect an organization’s critical systems. Purple is not a separate team, but rather a collaboration between the red team and the blue team. The red team is the offensive team that simulates attacks and exploits vulnerabilities in the organization’s systems. The blue team is the defensive team that monitors and protects the organization’s systems from real and simulated threats. The purple team exists to ensure and maximize the effectiveness of the red and blue teams by integrating the defensive tactics and controls from the blue team with the threats and vulnerabilities found by the red team into a single narrative that improves the overall security posture of the organization. Red, blue, and yellow are other types of teams involved in security testing, but they do not combine both offensive and defensive techniques. The yellow team is the team that builds software solutions, scripts, and other programs that the blue team uses in the security testing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1331; Penetration Testing: Understanding Red, Blue, & Purple Teams3

Exercising the right to be forgotten involves formally requesting the social media provider to delete all personal data associated with the account, ensuring removal from their servers and backups in accordance with privacy regulations.

Comprehensive and Detailed In-Depth Explanation:

The first step in securing a newly deployed server is toclose unnecessary service ports. Open ports can expose the server to unauthorized access and potential cyber threats. By closing unused ports, the attack surface is reduced, limiting the number of entry points available to attackers.

Updating the software version (B)andupgrading the OS version (D)are important security measures but should follow the step of securing open ports to prevent immediate exposure to threats.

Adding the device to the Access Control List (ACL) (C)is a step in network security but does not directly secure the server itself against potential attacks.

Closing unnecessary ports helps in minimizing the risk of network-based attacks, such asport scanning and exploitation of default services.

A strong authentication policy should enforcepassword length(e.g., minimum of 12-16 characters) andcomplexity(mix of uppercase, lowercase, numbers, and symbols). These measures significantlyreduce the risk of brute-force attacks.

Least privilege (C)relates to access control, not authentication policies.

Something you have (D)andbiometrics (F)pertain to multi-factor authentication (MFA) but are not password policy requirements.

Hacktivists are individuals or groups who use hacking to promote a political agenda, social cause, or philosophical beliefs. Their primary motivation is not personal gain but rather to draw attention to, or protest against, perceived injustices or causes.

Organizational risk tolerance is the primary factor determining how quickly and aggressively vulnerabilities should be remediated. Security+ SY0-701 explains that organizations have different appetites for risk depending on business needs, regulatory expectations, operational constraints, and financial impact.

A company with low risk tolerance may prioritize almost every vulnerability and remediate quickly.

A company with high risk tolerance may delay or accept some lower-impact risks.

This consideration directly influences patch prioritization, resource allocation, and mitigation timelines.

Option A—executive reporting—does not influence technical prioritization.

Option C—open-source intelligence—helps identify vulnerabilities but does not determine urgency.

Option D—the source of the reported risk—is irrelevant; what matters is severity and business impact.

Thus, B: The overall organizational risk tolerance is the key factor for prioritizing remediation.

A tabletop exercise is a discussion-based exercise where stakeholders gather to walk through the roles and responsibilities they would have during a specific situation, such as a security incident or disaster. This type of exercise is designed to identify gaps in planning and improve coordination among team members without the need for physical execution.

A two-person integrity security control is implemented to minimize the risk of errors or unauthorized actions. This control ensures that at least two individuals are involved in critical operations, which helps to verify the accuracy of the process and prevents unauthorized users from acting alone. It's a security measure commonly used in sensitive operations, like financial transactions or access to critical systems, to ensure accountability and accuracy.

Whaling is a type of phishing attack that targets high-profile individuals, such as executives, celebrities, or politicians. The attacker impersonates someone with authority or influence and tries to trick the victim into performing an action, such as transferring money, revealing sensitive information, or clicking on a malicious link. Whaling is also called CEO fraud or business email compromise2.

The log entries clearly show an attacker attempting to access sensitive system files by manipulating the filename parameter. The use of ../../../ is a classic indicator of a directory traversal attack, also called path traversal. This technique is used to move outside the intended web directory and access restricted locations on the server’s filesystem.

In this case, the attacker is attempting to read:

/etc/passwd — contains user account information

/etc/shadow — contains hashed password entries and is even more sensitive

The CompTIA Security+ SY0-701 exam describes directory traversal as an attack where unvalidated user input allows navigation to system directories, often using sequences like ../ to bypass file path restrictions. This is exactly what is shown in the logs.

File injection (A) would involve inserting malicious files or code, not reading system files.

Privilege escalation (B) requires exploiting a system to gain higher privileges, not just reading files.

Cookie forgery (D) involves manipulating session cookies and does not match the observed behavior.

Because the attacker is using path traversal patterns to access protected files, the correct answer is C. Directory traversal.

Full Disk Encryption (FDE) ensures that all data on the drive is encrypted, preventing unauthorized access even if the device is lost.

=================

A service level agreement (SLA) is a type of agreement that defines the expectations and responsibilities between a service provider and a customer. It usually includes the quality, availability, and performance metrics of the service, as well as the time frame in which the provider needs to respond to service requests, incidents, or complaints. An SLA can help ensure that the customer receives the desired level of service and that the provider is accountable for meeting the agreed-upon standards.

Infrastructure as Code (IaC) enables organizations to automate the provisioning, configuration, and deployment of servers through machine-readable scripts rather than manual processes. SY0-701 emphasizes IaC as a key component of DevOps and secure deployment pipelines. By using IaC, server builds become repeatable, standardized, version-controlled, and much faster.

This directly addresses the company's goals:

Better control: IaC ensures predictable, consistent configuration across all servers.

Standardization: Scripts eliminate drift by applying identical configurations.

Lower build time: Automation significantly accelerates server creation and eliminates manual intervention.

IoT (A) refers to Internet-connected smart devices and is unrelated to server deployment. PaaS (C) offers development platforms but does not automate infrastructure builds. ICS (D) refers to industrial control systems, not IT server architecture.

Therefore, the only correct architecture that meets all objectives is IaC, a foundational technology for modern automated infrastructure.

An image backup, also known as a full system backup, captures the entire contents of a system, including the operating system, applications, settings, and all data. This type of backup allows for a complete recovery of the system in case of a disaster, as it includes everything needed to restore the system to its previous state. This makes it the ideal choice for a systems administrator who needs to ensure the ability to recover the entire system, including the OS.

To reduce risky behaviors such as clicking suspicious emails, the first and most effective step is to implement a phishing awareness campaign that educates users about recognizing phishing attempts, the risks involved, and safe practices. Awareness training can significantly reduce successful phishing attacks by changing user behavior.

Updating policies (A) is important but does not directly affect user behavior immediately. Password management solutions (B) help with credential security but do not reduce phishing click rates. Issuing warning letters (C) is punitive and less effective than proactive education.

This approach aligns with Security Program Management principles emphasizing training and awareness as primary controls against phishing risks【6:Chapter 16†CompTIA Security+ Study Guide】.

 Labeling all laptops with asset inventory stickers and associating them with employee IDs can provide several security benefits for a company. Two of these benefits are:

A. If a security incident occurs on the device, the correct employee can be notified. An asset inventory sticker is a label that contains a unique identifier for a laptop, such as a serial number, a barcode, or a QR code. By associating this identifier with an employee ID, the security team can easily track and locate the owner of the laptop in case of a security incident, such as a malware infection, a data breach, or a theft. This way, the security team can notify the correct employee about the incident, and provide them with the necessary instructions or actions to take,such as changing passwords, scanning for viruses, or reporting the loss. This can help to contain the incident, minimize the damage, and prevent further escalation.

F. Company data can be accounted for when the employee leaves the organization. When an employee leaves the organization, the company needs to ensure that all the company data and assets are returned or deleted from the employee’s laptop. By labeling the laptop with an asset inventory sticker and associating it with an employee ID, the company can easily identify and verify the laptop that belongs to the departing employee, and perform the appropriate data backup, wipe, or transfer procedures. This can help to protect the company data from unauthorized access, disclosure, or misuse by the former employee or any other party.

The other options are not correct because they are not related to the security benefits of labeling laptops with asset inventory stickers and associating them with employee IDs. B. The security team will be able to send user awareness training to the appropriate device. User awareness training is a type of security education that aims to improve the knowledge and behavior of users regarding security threats and best practices. The security team can send user awareness training to the appropriate device by using the email address, username, or IP address of the device, not the asset inventory sticker or the employee ID. C. Users can be mapped to their devices when configuring software MFA tokens. Software MFA tokens are a type of multi-factor authentication that uses a software application to generate a one-time password or a push notification for verifying the identity of a user. Users can be mapped to their devices when configuring software MFA tokens by using the device ID, phone number, or email address of the device, not the asset inventory sticker or the employee ID. D. User-based firewall policies can be correctly targeted to the appropriate laptops. User-based firewall policies are a type of firewall rules that apply to specific users or groups of users, regardless of the device or location they use to access the network. User-based firewall policies can be correctly targeted to the appropriate laptops by using the username, domain, or certificate of the user, not the asset inventory sticker or the employee ID. E. When conducting penetration testing, the security team will be able to target the desired laptops. Penetration testing is a type of security assessment that simulates a real-world attack on a network or system to identify and exploit vulnerabilities. When conducting penetration testing, the security team will be able to target the desired laptops by using the IP address, hostname, or MAC address of the laptop, not the asset inventory sticker or the employee ID. References = CompTIA Security+ Study Guide (SY0-701), Chapter 1: General Security Concepts, page 17. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 1.4: Asset Management, video: Asset Inventory (6:12).

A jump server is a device or virtual machine that acts as an intermediary between a user’s workstation and a remote network segment. A jump server can be used to securely access servers or devices that are not directly reachable from the user’s workstation, such as database servers. A jump server can also provide audit logs and access control for the remote connections. A jump server is also known as a jump box or a jump host12.

RADIUS is a protocol for authentication, authorization, and accounting of network access. RADIUS is not a device or a method to access remote servers, but rather a way to verify the identity and permissions of users or devices that request network access34.

HSM is an acronym for Hardware Security Module, which is a physical device that provides secure storage and generation of cryptographic keys. HSMs are used to protect sensitive data and applications, such as digital signatures, encryption, and authentication. HSMs are not used to access remote servers, but rather to enhance the security of the data and applications that reside on them5 .

A load balancer is a device or software that distributes network traffic across multiple servers or devices, based on criteria such as availability, performance, or capacity. A load balancer can improve the scalability, reliability, and efficiency of network services, such as web servers, application servers, or database servers. A load balancer is not used to access remote servers, but rather to optimize the delivery of the services that run on them . References =

The IT manager is creating a Business Continuity Plan (BCP). A BCP describes how an organization will continue to operate during and after a disaster or global incident. It ensures that critical business functions remain operational despite adverse conditions, with a focus on minimizing downtime and maintaining essential services.

Physical security relates to protecting physical assets.

Change management ensures changes in IT systems are introduced smoothly, without disrupting operations.

Disaster recovery is a subset of business continuity but focuses specifically on recovering from IT-related incidents​​.

Impossible travel (A)refers to logins fromgeographically distant locations within a time period that makes travel between them physically impossible. In this case, a user logging in fromChicago and Rome within a short timeframetriggers this anomaly.

This is a strong indicator of acompromised accountorstolen credentialsbeing used elsewhere.

A false positive is a result that indicates a vulnerability or a problem when there is none. In this case, the vulnerability scanning report shows that the telnet service on port 23 is open and uses an insecure network protocol. However, the security analyst performs a test using nmap and a script that checks for telnet encryption support. The result shows that the telnet server supports encryption, which means that the data transmitted between the client and the server can be protected from eavesdropping. Therefore, the reported vulnerability is a false positive and does not reflect the actual security posture of the server. The security analyst should verify the encryption settings of the telnet server and client and ensure that they are configured properly3. References: 3: Telnet Protocol - Can You Encrypt Telnet?

Internal audits are conducted within an organization to independently assess and evaluate the effectiveness of internal controls, policies, and procedures. A key benefit of internal audits is the identification of control gaps or weaknesses that can then be remediated before they lead to security incidents or compliance failures.

Unlike external audits, internal audit findings are primarily for management and internal stakeholders, focusing on improving security posture and operational efficiency. Reports generated are formal and documented to ensure accountability, and internal audits do not replace the need for external audits, which provide independent verification to external parties like regulators or shareholders.

This role of internal audits in identifying deficiencies and driving remediation efforts is emphasized in the Security Program Management and Oversight domain of the SY0-701 exam【7:Chapter 5†CompTIA Security+ Practice Tests】.

Smishing is a type of phishing attack that uses text messages or common messaging apps to trick victims into clicking on malicious links or providing personal information. The scenario in the question describes a smishing attack that uses pretexting, which is a form of social engineering that involves impersonating someone else to gain trust or access. The unknown number claims to be the company’s CEO and asks the employee to purchase gift cards, which is a common scam tactic. Vishing is a similar type of attack that uses phone calls or voicemails, while phishing is a broader term that covers any email-based attack. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 771; Smishing vs. Phishing: Understanding the Differences2

Detailed Explanation:Third-party attestation involves an external, independent party performing a network security assessment and providing documented proof, ensuring objectivity and compliance with regulatory or client requirements.

Changing the default password for the local administrator account on a VPN appliance is a basic security measure that would have most likely prevented the unexpected login to the remote management interface. Default passwords are often easy to guess or publicly available, and attackers can use them to gain unauthorized access to devices and systems. Changing the default password to a strong and unique one reduces the risk of brute-force attacks and credential theft. Using least privilege, assigning individual user IDs, and reviewing logs more frequently are also good security practices, but they are not as effective as changing the default password in preventing the unexpected login. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 116; Local Admin Accounts - Security Risks and Best Practices (Part 1)

Security Orchestration, Automation, and Response (SOAR) systems help organizations automate repetitive security tasks, reduce manual intervention, and improve the efficiency of security operations. By integrating with various security tools, SOAR can automatically respond to incidents, helping to enhance threat detection while reducing the manual workload on security analysts.

A non-disclosure agreement (NDA) restricts employees from sharing proprietary or confidential information when they leave the company. Legal consequences may result from violating an NDA.

A bug bounty is a program that rewards security researchers for finding and reporting vulnerabilities in an application or system. Bug bounties are often used by companies to improve their security posture and incentivize ethical hacking. A bug bounty program typically defines the scope, rules, and compensation for the researchers. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 10. CompTIA Security+ (SY0-701) Certification Exam Objectives, Domain 1.1, page 2.

In the context of the CompTIA Security+ SY0-701 exam, orchestration is the most appropriate answer because it directly aligns with the automation of repetitive, operational security tasks. Orchestration refers to the coordinated execution of automated processes to streamline workflows, reduce administrative burden, and ensure consistent outcomes. Creating a script to automate user account creation for a large number of users is a textbook example of orchestration in action.

The Security+ SY0-701 study guide emphasizes that automation and orchestration are essential components of modern security operations. They are used to minimize human error, improve efficiency, and enforce consistency across environments. Manual account creation is error-prone, especially at scale, and can lead to misconfigured permissions, inconsistent group memberships, or skipped security steps. Orchestration ensures that predefined steps—such as creating user accounts, assigning roles, applying access controls, enforcing password policies, and logging actions—are executed reliably every time.

The other options do not fit the scenario. Off-the-shelf software refers to prebuilt commercial solutions rather than a custom script. A baseline defines a standard configuration state but does not automate actions. Policy enforcement ensures compliance with rules but does not perform the operational task itself. The key distinction is that orchestration focuses on execution and coordination of tasks, not governance or standards.

From a Security+ operational standpoint, orchestration supports secure identity and access management by ensuring accounts are provisioned consistently and in alignment with organizational policies. It also improves auditability and accountability by enabling predictable, repeatable processes. Therefore, orchestration is the correct and most secure solution for automating large-scale account creation.

An application allow list is a security technique that specifies which applications are authorized to run on a system and blocks all other applications. An application allow list can best protect against an employee inadvertently installing malware on a company system because it prevents the execution of any unauthorized or malicious software, such as viruses, worms, trojans, ransomware, or spyware. An application allow list can also reduce the attack surface and improve the performance of the system. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 11: Secure Application Development, page 551 1

Data Loss Prevention (DLP) systems are typically configured to protect sensitive data such as Personally Identifiable Information (PII) within an organization. DLP tools enforce policies that monitor, detect, and block the unauthorized transmission of sensitive data. By leveraging the organization’s existing labeling and classification system, DLP solutions can identify and protect data based on its classification, ensuring that PII is appropriately secured according to organizational policies.

The requirements point to a cloud-delivered, remote-user-first architecture that provides secure connectivity and security controls as an integrated service. Secure Access Service Edge (SASE) matches this because it combines remote connectivity capabilities (often replacing or modernizing traditional VPN approaches) with cloud-based security services, including firewalling, in a way that supports distributed users and resilient global access. The Study Guide explicitly states: “Secure Access Service Edge (SASE… ) combines virtual private networks, SD-WAN, and cloud-based security tools like firewalls, cloud access security brokers (CASBs), and zero-trust networks to provide secure access for devices regardless of their location.” This directly aligns with a fully remote workforce (“regardless of their location”), VPN capability, and an integrated firewall (“cloud-based security tools like firewalls”).

Why the other options don’t fit as well: IPS is a specific protective control, not an end-to-end remote access architecture; SIEM is for log aggregation/correlation and monitoring, not VPN + firewall delivery; and CASB is a component used to enforce cloud policy, but the guide distinguishes it as a policy enforcement point rather than a full connectivity + firewall architecture: “A CASB is a policy enforcement point…” . Therefore, SASE is the best match.

FIM stands for File Integrity Monitoring, which is a method to secure data by detecting any changes or modifications to files, directories, or registry keys. FIM can help a security administrator track any unauthorized or malicious changes to the data, as well as verify the integrity and compliance of the data. FIM can also alert the administrator of any potential breaches or incidents involving the data.

Some of the benefits of FIM are:

It can prevent data tampering and corruption by verifying the checksums or hashes of the files.

It can identify the source and time of the changes by logging the user and system actions.

It can enforce security policies and standards by comparing the current state of the data with the baseline or expected state.

It can support forensic analysis and incident response by providing evidence and audit trails of the changes.

SSO stands for single sign-on, which is a method of authentication that allows users to access multiple applications or services with one set of credentials. SSO reduces the number of credentials employees need to maintain and simplifies the login process. SSO can also improve security by reducing the risk of password reuse, phishing, and credential theft. SSO can be implemented using various protocols, such as SAML, OAuth, OpenID Connect, and Kerberos, that enable the exchange of authentication information between different domains or systems. SSO is commonly used for accessing SaaS applications, such as Office 365, Google Workspace, Salesforce, and others, using domain credentials123.

B. LEAP stands for Lightweight Extensible Authentication Protocol, which is a Cisco proprietary protocol that provides authentication for wireless networks. LEAP is not related to SaaS applications or domain credentials4.

C. MFA stands for multi-factor authentication, which is a method of authentication that requires users to provide two or more pieces of evidence to prove their identity. MFA can enhance security by adding an extra layer of protection beyond passwords, such as tokens, biometrics, or codes. MFA is not related to SaaS applications or domain credentials, but it can be used in conjunction with SSO.

D. PEAP stands for Protected Extensible Authentication Protocol, which is a protocol that provides secure authentication for wireless networks. PEAP uses TLS to create an encrypted tunnel between the client and the server, and then uses another authentication method, such as MS-CHAPv2 or EAP-GTC, to verify the user’s identity. PEAP is not related to SaaS applications or domain credentials.

Salting is the process of adding extra random data to a password or other data before applying a one-way data transformation algorithm, such as a hash function. Salting increases the complexity and randomness of the input data, making it harder for attackers to guess or crack the original data using precomputed tables or brute force methods. Salting also helps prevent identicalpasswords from producing identical hash values, which could reveal the passwords to attackers who have access to the hashed data. Salting is commonly used to protect passwords stored in databases or transmitted over networks. References =

Group policies can inadvertently introduce misconfigurations, such as enabling insecure settings or failing to disable legacy protocols, increasing vulnerabilities.

Zero-day (B) are previously unknown vulnerabilities, malicious updates (C) are attacker-controlled, and supply chain (D) risks come from third-party components.

Misconfiguration vulnerabilities are commonly introduced during changes and are emphasized in Security Operations【6:Chapter 14†CompTIA Security+ Study Guide】.

Allowing risky protocols like SMB and RDP from the internet to a controlled VLAN is commonly done to create a honeynet, a deliberately vulnerable network environment used to attract attackers and study their behaviors without risking production systems.

Building a file-sharing site (A) or preparing for a pentest (B) typically wouldn't require exposing SMB and RDP broadly. SASE integration (C) focuses on cloud security access and doesn't involve opening such protocols indiscriminately.

Honeynets are described as a deception technology in the Security Architecture domain【6:Chapter 9†CompTIA Security+ Study Guide】.

Preparation is the phase in the incident response process when a security analyst reviews roles and responsibilities, as well as the policies and procedures for handling incidents. Preparation also involves gathering and maintaining the necessary tools, resources, and contacts for responding to incidents. Preparation can help a security analyst to be ready and proactive when an incident occurs, as well as to reduce the impact and duration of the incident.

Some of the activities that a security analyst performs during the preparation phase are:

Defining the roles and responsibilities of the incident response team members, such as the incident manager, the incident coordinator, the technical lead, the communications lead, and the legal advisor.

Establishing the incident response plan, which outlines the objectives, scope, authority, and procedures for responding to incidents, as well as the escalation and reporting mechanisms.

Developing the incident response policy, which defines the types and categories of incidents, the severity levels, the notification and reporting requirements, and the roles and responsibilities of the stakeholders.

Creating the incident response playbook, which provides the step-by-step guidance and checklists for handling specific types of incidents, such as denial-of-service, ransomware, phishing, or data breach.

Acquiring and testing the incident response tools, such as network and host-based scanners, malware analysis tools, forensic tools, backup and recovery tools, and communication and collaboration tools.

Identifying and securing the incident response resources, such as the incident response team, the incident response location, the evidence storage, and the external support.

Building and maintaining the incident response contacts, such as the internal and external stakeholders, the law enforcement agencies, the regulatory bodies, and the media.

Serverless architecture allows companies to deploy code without managing the underlying infrastructure. This approach significantly reduces the time and expense involved in code deployment because developers can focus solely on writing code, while the cloud provider manages the servers, scaling, and maintenance. Serverless computing also enables automatic scaling and pay-per-execution billing, which further optimizes costs.

CompTIA Security+ SY0-701 Course Content: The course covers cloud technologies, including serverless architectures, which are highlighted as a method to streamline and reduce costs associated with code deployment​​​.

Integrating each SaaS solution with an Identity Provider (IdP) is the most effective way to address the security issue. This approach allows for Single Sign-On (SSO) capabilities, where users can access multiple SaaS applications with a single set of credentials while maintaining strong password policies across all services. It simplifies the user experience and ensures consistent security enforcement across different SaaS platforms.

Threat hunting is the process of proactively searching for signs of malicious activity or compromise in a network, rather than waiting for alerts or indicators of compromise (IOCs) to appear. Threat hunting can help identify new tactics, techniques, and procedures (TTPs) used by malicious actors, as well as uncover hidden or stealthy threats that may have evaded detection by security tools. Threat hunting requires a combination of skills, tools, and methodologies, such as hypothesis generation, data collection and analysis, threat intelligence, and incident response. Threat hunting can also help improve the security posture of an organization by providing feedback and recommendations for security improvements. References = CompTIA Security+ Certification Exam Objectives, Domain 4.1: Given a scenario, analyze potential indicators of malicious activity. CompTIA Security+ Study Guide (SY0-701), Chapter 4: Threat Detection and Response, page 153. Threat Hunting – SY0-701 CompTIA Security+ : 4.1, Video 3:18. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 3.

A playbook is a documented set of procedures that outlines the step-by-step response to specific types of cybersecurity incidents. Security Operations Centers (SOCs) use playbooks to improve consistency, efficiency, and accuracy during incident response. Playbooks help ensure that thecorrect procedures are followed based on the type of incident, ensuring swift and effective remediation.

Frameworks provide general guidelines for implementing security but are not specific enough for incident response procedures.

Baselines represent normal system behavior and are used for anomaly detection, not incident response guidance.

Benchmarks are performance standards and are not directly related to incident response​​.

Dumpster diving is an attack method where attackers search through physical waste, such as discarded documents and printouts, to find sensitive information that has not been properly disposed of. In the context of printing centers, this could involve attackers retrieving printed documents containing confidential data that were improperly discarded without shredding or other secure disposal methods. This emphasizes the importance of proper disposal and physical security measures in cyber hygiene practices.

References =

Wiping involves securely erasing data by overwriting the hard drive, ensuring the information is unrecoverable. It is cost-effective compared to physical destruction methods like shredding.

=================

Compromised vendor email accounts often lead to business email compromise (BEC) attacks where attackers send malicious or unexpected requests appearing from trusted sources. Training users to be alert to unexpected requests even if they appear to come from familiar addresses is critical in preventing such attacks.

Refraining from clicking images (A) is less effective than being vigilant about suspicious content and requests. Deleting emails from unknown providers (B) is not practical, as some legitimate emails come from unknown senders. Requiring invoices as attachments (C) can increase risk by encouraging users to open potentially malicious attachments.

This user awareness tactic is emphasized in the Security Program Management and Security Awareness training in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

Disabling access is an automation use case that would best enhance the security posture of an organization by rapidly updating permissions when employees leave a company. Disabling access is the process of revoking or suspending the access rights of a user account, such as login credentials, email, VPN, cloud services, etc. Disabling access can prevent unauthorized or malicious use of the account by former employees or attackers who may have compromised the account. Disabling access can also reduce the attack surface and the risk of data breaches or leaks. Disabling access can be automated by using scripts, tools, or workflows that can trigger the action based on predefined events, such as employee termination, resignation, or transfer. Automation can ensure that the access is disabled in a timely, consistent, and efficient manner, without relying on manual intervention or human error.

Injecting malicious payloads into a hypervisor and accessing the host system is an example of VM escape, where the isolation between virtual machines and the host breaks down, allowing unauthorized control.

Cross-site scripting (B), malicious updates (C), and SQL injection (D) are unrelated to hypervisor host access.

VM escape is a critical vulnerability unique to virtualized environments described in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

Static analysis is the process of examining a file without executing it to identify known malicious signatures, suspicious patterns, strings, embedded resources, or code fragments. When a security engineer needs to quickly extract a signature from a known malicious file, static analysis is the most efficient approach. This method allows analysts to inspect binary code, metadata, file headers, and hashes such as MD5/SHA-256.

According to Security+ SY0-701, static analysis is ideal for identifying:

Malware signatures

Embedded malicious payloads

Hash values for detection

Known indicators of compromise (IOCs)

Sandboxing (B) is used to observe behavior by executing the malware, which takes longer and is unnecessary when the malware is already known. Network traffic analysis (C) is used to observe communications, not generate file signatures. Package monitoring (D) refers to monitoring OS-level changes and system calls, which is a dynamic method.

Static analysis aligns with the requirement for quick identification, making option A the correct choice.

Detailed Explanation:Firewall logs provide details of all network traffic, including connections to and from IoT devices. They are typically the first source of evidence for identifying the time of an exploit. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Log Analysis for Incident Response"​​.

Detailed Explanation:Host isolation ensures that a device is separated from the network, preventing it from accessing or being accessed by other network resources. This is typically achieved by quarantining the device. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Isolation and Containment"​​.

Full-disk encryption (FDE) protects the contents of storage media, which is a classic data-at-rest control. The Study Guide explains the “three situations” relevant to confidentiality—at rest, in transit, and in use—and then specifically ties disk encryption/FDE to protecting stored data: “Data at rest, or stored data, is that which resides in a permanent location awaiting access… Examples… hard drives…” It then describes FDE as an encryption method applied to disks: “Full-disk encryption (FDE) is a form of encryption where all the data on a hard drive is automatically encrypted, including the operating system and system files… In the case of loss or theft, FDE can prevent unauthorized access to all data on the hard drive.”

That is exactly the definition of protecting data at rest—it is intended to prevent disclosure if a laptop/workstation is lost, stolen, or the drive is removed. This is not masking (hiding parts of fields), not data in transit (network encryption like TLS/VPN), not obfuscation (making code hard to understand), and not data sovereignty (jurisdiction/location requirements). Therefore, deploying FDE on workstations is a data-at-rest protection strategy.

Encryption at rest is a strategy that protects data stored on a device, such as a laptop, by converting it into an unreadable format that can only be accessed with a decryption key or password. Encryption at rest can prevent data loss on stolen laptops by preventing unauthorized access to the data, even if the device is physically compromised. Encryption at rest can also help comply with data privacy regulations and standards that require data protection. Masking, data classification, and permission restrictions are other strategies that can help protect data, but they may not be sufficient or applicable for data stored on laptops. Masking is a technique that obscures sensitive data elements, such as credit card numbers, with random characters or symbols, but it is usually used for data in transit or in use, not at rest. Data classification is a process that assigns labels to data based on its sensitivity and business impact, but it does not protect the data itself. Permission restrictions are rules that define who can access, modify, or delete data, but they may not prevent unauthorized access if the laptop is stolen and the security controls are bypassed. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 17-18, 372-373

Failure to comply with right-to-be-forgotten (data privacy) regulations can lead to significant fines imposed by regulatory authorities like GDPR enforcers. Such laws require companies to delete personal data upon user request.

Data breaches (B) are security incidents; revenue loss (C) and blackmail (D) may occur indirectly but fines are the direct legal consequence.

Regulatory compliance and consequences are critical topics in Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】

Password spraying is a type of attack where an attacker tries a small number of commonly used passwords across a large number of accounts. The event logs showing failed login attempts for many user accounts from the same IP address are indicative of a password spraying attack, where the attacker is attempting to gain access by guessing common passwords.

References = CompTIA Security+ SY0-701 study materials, particularly in the domain of identity and access management and common attack vectors like password spraying​​.

Non-compliance with internal policies, such as corporate security policies, falls under internal non-compliance. These are rules created and enforced within the organization to maintain security standards.

External non-compliance (A) refers to violations of outside regulations or laws. Standards (B) are generally established best practices or industry guidelines, and regulation (C) refers to legal or governmental requirements.

Internal compliance management is a key focus area in the Security Program Management domain of SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

Industrial Control Systems (ICS) are engineered to operate in rugged, mission-critical environments such as manufacturing floors, refineries, gas pipelines, nuclear plants, and water treatment facilities. These systems are designed to remain operational for decades, often with minimal remote-management capability and limited update cycles. ICS architectures frequently use proprietary protocols and controls, many of which were developed long before modern cybersecurity concerns existed.

Security+ SY0-701 notes that ICS environments include SCADA systems, PLCs, actuators, sensors, and controllers that must function reliably under extreme temperature, pressure, vibration, and industrial stress conditions. Because downtime may impact safety, critical infrastructure, or national security, ICS devices avoid frequent patching and instead rely on isolation, segmentation, and compensating controls.

Microservers (B) are small, lightweight servers—not rugged systems. Containers (C) are virtualized application environments. IoT devices (D) are consumer or commercial smart devices, not industrial-grade long-lifespan systems.

Thus, the correct answer is A: ICS.

A Host-based Intrusion Prevention System (HIPS) provides both preventive and detective security controls. Security+ SY0-701 describes HIPS as a host-level security solution that monitors system behavior, blocks malicious activity, and logs suspicious events.

It functions as a preventive control (B) because it can:

Stop malware execution

Block unauthorized changes

Prevent exploit attempts

Enforce endpoint protection policies

It is also a detective control (F) because it can:

Record attempted attacks

Identify suspicious activities

Generate alerts for security teams

Directive controls (A) refer to policies; physical controls (C) refer to locks and barriers; corrective controls (D) restore systems after an incident; compensating controls (E) substitute for missing primary controls.

Therefore, the two correct answers are B (Preventive) and F (Detective).

Badge access and access control vestibule are two of the best ways to ensure only authorized personnel can access a secure facility. Badge access requires the personnel to present a valid and authenticated badge to a reader or scanner that grants or denies access based on predefined rules and permissions. Access control vestibule is a physical security measure that consists of a small room or chamber with two doors, one leading to the outside and one leading to the secure area. The personnel must enter the vestibule and wait for the first door to close and lock before the second door can be opened. This prevents tailgating or piggybacking by unauthorized individuals. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 4, pages 197-1981

SCADA (Supervisory Control and Data Acquisition) systems commonly manage industrial equipment, including PLCs (Programmable Logic Controllers). Historically, SCADA environments often lack encryption for management traffic due to legacy equipment and protocols. This makes SCADA the most likely environment where unencrypted PLC management traffic can be observed.

An engineer should recommend the decommissioning of a network device when the device poses a security risk or a compliance violation to the enterprise environment. A device that cannot meet the encryption standards or receive authorized updates is vulnerable to attacks and breaches, and may expose sensitive data or compromise network integrity. Therefore, such a device should be removed from the network and replaced with a more secure and updated one.

After completing a vulnerability assessment and remediating the identified vulnerabilities, the next step is to rescan the network to verify that the vulnerabilities have been successfully fixed and no new vulnerabilities have been introduced. A vulnerability assessment is a process of identifying and evaluating the weaknesses and exposures in a network, system, or application that could be exploited by attackers. A vulnerability assessment typically involves using automated tools, such as scanners, to scan the network and generate a report of the findings. The report may include information such as the severity, impact, and remediation of the vulnerabilities. The operations team is responsible for applying the appropriate patches, updates, or configurations to address the vulnerabilities and reduce the risk to the network. A rescan is necessary to confirm that the remediation actions have been effective and that the network is secure.

Conducting an audit, initiating a penetration test, or submitting a report are not the next steps after completing a vulnerability assessment and remediating the vulnerabilities. An audit is a process of reviewing and verifying the compliance of the network with the established policies, standards, and regulations. An audit may be performed by internal or external auditors, and it may use the results of the vulnerability assessment as part of the evidence. However, an audit is not a mandatory step after a vulnerability assessment, and it does not validate the effectiveness of the remediation actions.

A penetration test is a process of simulating a real-world attack on the network to test the security defenses and identify any gaps or weaknesses. A penetration test may use the results of the vulnerability assessment as a starting point, but it goes beyond scanning and involves exploiting the vulnerabilities to gain access or cause damage. A penetration test may be performed after a vulnerability assessment, but only with the proper authorization, scope, and rules of engagement. A penetration test is not a substitute for a rescan, as it does not verify that the vulnerabilities have been fixed.

Submitting a report is a step that is done after the vulnerability assessment, but before the remediation. The report is a document that summarizes the findings and recommendations of the vulnerability assessment, and it is used to communicate the results to the stakeholders and the operations team. The report may also include a follow-up plan and a timeline for the remediation actions. However, submitting a report is not the final step after the remediation, as it does not confirm that the network is secure.

Access control lists (ACLs) are rules that specify which users or groups can access which resources on a file server. They can help restrict access to confidential data by granting or denying permissions based on the identity or role of the user. In this case, the administrator can use ACLs to quickly modify the access rights of the users and prevent them from accessing the data they are not authorized to see. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308 1

Centralized authentication (such as Active Directory or LDAP) combined with proper password policies helps prevent the reuse of the same local credentials across multiple systems, reducing the risk of lateral movement during attacks like credential reuse or pass-the-hash.

Mobile Device Management (MDM) platforms enforce security policies on mobile devices, including preventing or detecting jailbreaking, which is the act of removing manufacturer restrictions on devices. Jailbroken devices bypass security protections, allow installation of unauthorized apps, expose system files, and greatly increase risk.

Security+ SY0-701 identifies MDM as a key defense for mobile ecosystems, providing controls such as:

Jailbreak/root detection

Remote wipe

App allow/deny lists

Configuration enforcement

Encryption enforcement

TPM (A) is hardware-based protection unrelated to MDM. Buffer overflow (B) and SQL injection (D) are software coding vulnerabilities not affected by mobile device policy enforcement.

Thus, the correct answer is C: Jailbreaking.

Classification is the process of assigning labels to files or data based on sensitivity, business value, or regulatory requirements. Proper classification guides handling, access controls, and protection measures.

Verification (A) and certification (B) are validation processes, and inventory (D) is a listing of assets.

Data classification is a foundational data governance control in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

To ensure that all systems requiring the patch are updated, the systems administrator must maintain an accurate asset inventory. This inventory lists all hardware and software assets within the organization, allowing the administrator to identify which systems are affected by the patch and ensuring that none are missed during the update process.

Network enumeration is used to discover devices on a network but doesn't track software that requires patching.

Data certification and procurement process are unrelated to tracking systems for patching purposes​​.

WPA2-Enterprise is designed for environments where users authenticate with unique, individual credentials backed by an enterprise identity store, rather than a shared preshared key. The Study Guide explicitly states: “WPA2-Enterprise relies on a RADIUS authentication server as part of an 802.1X implementation for authentication. Users can thus have unique credentials and be individually identified.” That maps directly to the requirement that users verify identity against the company’s identity services using individual credentials. It further explains how this is implemented operationally: “802.1X is an IEEE standard for access control… In wireless networks, 802.1X is used to integrate with RADIUS servers, allowing enterprise users to authenticate and gain access to the network.”

Therefore, the correct configuration step is enabling 802.1X and tying authentication into the organization’s identity source (commonly a corporate directory). The other choices don’t correctly “apply RADIUS” for WPA2-Enterprise: self-signed certs are not universally required for all EAP types and can introduce trust issues; MAC filters are weak and spoofable; and MFA might be beneficial but is not the fundamental step that enables RADIUS-backed WPA2-Enterprise authentication.

The chmod command is used to change file permissions on Unix and Linux systems. If the /etc/shadow file has permissions beyond the baseline recommendation, the systems administrator should use chmod to modify the file's permissions, ensuring it adheres to the security baseline and limits access to authorized users only.

A physical security control is a device or mechanism that prevents unauthorized access to a physical location or asset. An access control vestibule, also known as a mantrap, is a physical security control that consists of a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. This prevents unauthorized individuals from following authorized individuals into the facility, a practice known as piggybacking or tailgating. A photo ID check is another form of physical security control that verifies the identity of visitors. Managerial, technical, and operational security controls are not directly related to physical access, but rather to policies, procedures, systems, and processes that support security objectives. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 341; Mantrap (access control) - Wikipedia2

Shadow IT is the term used to describe the use of unauthorized or unapproved IT resources within an organization. The marketing department set up its own project management software without telling the appropriate departments, such as IT, security, or compliance. This could pose a risk to the organization’s security posture, data integrity, and regulatory compliance1.

The security engineer is likely to deploy a Web Application Firewall (WAF) to protect the new web portal service. A WAF specifically protects web applications by filtering, monitoring, and blocking HTTP requests based on a set of rules. This is crucial for preventing common attacks such as SQL injection, cross-site scripting (XSS), and other web-based attacks that could compromise the web service.

Layer 4 firewall operates primarily at the transport layer, focusing on IP address and port filtering, making it unsuitable for web application-specific threats.

NGFW (Next-Generation Firewall) provides more advanced filtering than traditional firewalls, including layer 7 inspection, but the WAF is tailored specifically for web traffic.

UTM (Unified Threat Management) offers a suite of security tools in one package (like antivirus, firewall, and content filtering), but for web application-specific protection, a WAF is the best fit​​​.

When multiple Wireless Access Points (WAPs) are using similar frequencies with high power settings, it can cause channel overlap, leading to interference and connectivity issues. This is likely the reason why mobile users are unable to access the internet in the lobby. Evaluating and adjusting the channel settings on the WAPs to avoid overlap is crucial to resolving the connectivity problems.

The Online Certificate Status Protocol (OCSP) is a technology designed to check the revocation status of digital certificates in real-time without requiring the client to download entire revocation lists. Unlike Certificate Revocation Lists (CRLs), which are periodically updated and can be large, OCSP queries an OCSP responder to receive the status of a specific certificate.

OCSP is considered passive verification because it allows clients to check a certificate's current validity status on-demand without maintaining local copies of revocation data. The OCSP responder returns whether the certificate is valid, revoked, or expired.

Trusted Platform Module (TPM) is hardware for secure key storage, and Certificate Signing Request (CSR) is a request for certificate issuance; neither is used for verifying certificate expiration status.

The differences and roles of OCSP and CRLs are thoroughly covered in the Cryptography and PKI chapter of the SY0-701, where OCSP is highlighted as the more efficient and real-time method to verify certificate status passively【6:Chapter 7†CompTIA Security+ Study Guide】.

The company should request a certification from the vendor that confirms the storage array has been disposed of securely and in compliance with the company’s policies and standards. A certification provides evidence that the vendor has followed the proper procedures and methods to destroy the classified data and prevent unauthorized access or recovery. A certification may also include details such as the date, time, location, and method of disposal, as well as the names and signatures of the personnel involved. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 3, page 1441

The right to be forgotten refers to an individual’s legal right, under regulations such as GDPR, to request the deletion of all personal data held about them by an organization. This gives individuals control over their digital footprint and privacy.

Impersonation occurs when an attacker or unauthorized user is granted access (authorized) by masquerading as a legitimate user, effectively bypassing or exploiting the authentication process. This means authorization is mistakenly granted before proper authentication.

Privilege escalation (A) involves gaining higher access after authentication. Race conditions (B) are timing vulnerabilities. Tailgating (C) refers to physical unauthorized access by following an authorized person.

Impersonation is a well-known identity attack vector detailed in the Threats and Vulnerabilities domain of SY0-701【6:Chapter 4†CompTIA Security+ Study Guide】.

Organized crime is a type of threat actor that is motivated by financial gain and often operates across national borders. Organized crime groups may be hired by foreign governments to conduct cyberattacks on critical systems located in other countries, such as power grids, military networks, or financial institutions. Organized crime groups have the resources, skills, and connections to carry out sophisticated and persistent attacks that can cause significant damage and disruption12. References = 1: Threat Actors - CompTIA Security+ SY0-701 - 2.1 2: CompTIA Security+ SY0-701 Certification Study Guide

Job rotation is a strategy used in organizations to detect and prevent fraud by periodically assigning employees to different roles within the organization. This approach helps ensure that no single employee has exclusive control over a specific process or set of tasks for an extended period, thereby reducing the opportunity for fraudulent activities to go unnoticed. By rotating roles, organizations can uncover irregularities and discrepancies that might have been concealed by an employee who had prolonged access to sensitive functions. Job rotation also promotes cross-training, which can enhance the organization's overall resilience and flexibility.

When investigating abnormal outbound traffic originating from a specific endpoint, endpoint logs are the most appropriate first data source to review. According to CompTIA Security+ SY0-701, endpoint logs provide detailed visibility into process execution, user actions, service creation, network connections initiated by applications, and security agent detections. This context is critical for determining which process initiated the encrypted traffic and why it is using non-standard ports.

Because the traffic is encrypted, packet captures (D) would reveal limited payload information and are more resource-intensive. Endpoint logs can quickly identify suspicious executables, command-line arguments, parent-child process relationships, and persistence mechanisms that indicate malware or command-and-control activity. Modern EDR tools rely heavily on endpoint telemetry for exactly this reason.

Application logs (A) may be useful later but are limited to specific applications. Vulnerability scans (B) identify weaknesses, not active malicious behavior.

Security+ SY0-701 emphasizes starting investigations as close to the suspected source as possible. Since the activity originates from a corporate endpoint, endpoint logs provide the fastest and most relevant confirmation of whether the traffic is malicious.

A host-based firewall controls incoming and outgoing network traffic on a device by enforcing security rules, effectively blocking unwanted or insecure communications. It is specifically designed to protect the device from unauthorized access and malicious traffic.

System hardening (A) reduces vulnerabilities by disabling unnecessary services and patching but does not control communications dynamically. Intrusion detection systems (C) detect suspicious traffic but typically do not block it (unless paired with prevention). Anti-malware (D) protects against malicious software but not directly network communication filtering.

Host-based firewalls are a fundamental component of endpoint security highlighted in the Security Operations domain of SY0-701【6:Chapter 11†CompTIA Security+ Study Guide】.

The scenario suggests that only the employees who used the kiosks inside the building had their credentials compromised. Since the time-keeping website is accessible from the internet, it is possible that a malicious actor exploited an unpatched vulnerability in the site, allowing them to inject malicious code that captured the credentials of those who logged in from the kiosks. This is a common attack vector for stealing credentials from web applications.

CompTIA Security+ SY0-701 Course Content: The course discusses web application vulnerabilities and how attackers can exploit them to steal credentials​​.

Active reconnaissance is a type of reconnaissance that involves sending packets or requests to a target and analyzing the responses. Active reconnaissance can reveal information such as open ports, services, operating systems, and vulnerabilities. However, active reconnaissance is also more likely to be detected by the target or its security devices, such as firewalls or intrusion detection systems. Port and service scans are examples of active reconnaissance techniques, as they involve probing the target for specific information. References = CompTIA Security+ Certification Exam Objectives, Domain 1.1: Given a scenario, conduct reconnaissance using appropriate techniques and tools. CompTIA Security+ Study Guide (SY0-701), Chapter 2: Reconnaissance and Intelligence Gathering, page 47. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 1.

Code signing is a technique that uses cryptography to verify the authenticity and integrity of the code created by the company. Code signing involves applying a digital signature to the code using a private key that only the company possesses. The digital signature can be verified by anyone who has the corresponding public key, which can be distributed through a trusted certificate authority. Code signing can prevent unauthorized modifications, tampering, or malware injection into the code, and it can also assure the users that the code is from a legitimate source. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 74.

Data exfiltration is a technique that attackers use to steal sensitive data from a target system or network by transmitting it through DNS queries and responses. This method is often used in advanced persistent threat (APT) attacks, in which attackers seek to persistently evade detection in the target environment. A large amount of unusual DNS queries to systems on the internet over short periods of time during non-business hours is a strong indicator of data exfiltration. A worm, a logic bomb, and ransomware would not use DNS queries to communicate with their command and control servers or perform their malicious actions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 487; Introduction to DNS Data Exfiltration; Identifying a DNS Exfiltration Attack That Wasn’t Real — This Time

Detailed Explanation:Mean Time to Repair (MTTR) is a key metric in risk management, reflecting the time required to repair a failed component, such as a generator, and restore operations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Business Continuity Metrics"​​.

Upgrading end-of-support operating systemsisone of the most effective ways to reduce the attack surface. Unsupported OS versionsno longer receive security patches, making them prime targets for attackers.Removing outdated softwareensures that known vulnerabilities cannot be exploited.

A (honeynet)is used for threat analysis, not reducing the attack surface.

B (Group Policy)helps enforce security policies butdoes not address outdated vulnerabilities.

C (High availability)focuses on uptime, not security risk reduction.

Poor input validation in databases typically leads to SQL Injection (SQLi) vulnerabilities, where attackers manipulate input fields to execute arbitrary SQL commands and gain unauthorized data access or control.

XSS (A) affects web applications' output rendering, command injection (B) affects OS commands, and buffer overflow (C) affects memory management, so they don't directly relate to database input validation.

SQLi is a critical vulnerability extensively covered in the Application Security domain【6:Chapter 6†CompTIA Security+ Study Guide】.

ATabletop exercise (D)is adiscussion-based simulationof an incident scenario. It allows security teams towalk through procedures, responsibilities, and communicationsin alow-pressure environment, improving readiness without impacting operations.

It is specifically designed toprepare teams for real-world incident handling.

Data classification is the process of assigning labels or tags to data based on its sensitivity, value, and risk. Data classification is the first step in a data loss prevention (DLP) solution, as it helps to identify what data needs to be protected and how. By applying classifications to the data, the security administrator can define appropriate policies and rules for the DLP solution to prevent the exfiltration of sensitive customer data. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 8: Data Protection, page 323. CompTIA Security+ Practice Tests: Exam SY0-701, 3rd Edition, Chapter 8: Data Protection, page 327.

SOAR (Security Orchestration, Automation, and Response) platforms enable security teams to automate workflows, prioritize alerts, and manage remediation activities, helping to handle the volume of cloud misconfiguration alerts efficiently.

CASB (A) provides visibility and control for cloud services but is less focused on orchestration. IAM (B) manages identities and permissions, and XDR (D) is extended detection but does not provide workflow automation.

SOAR integration is critical for cloud security operations discussed in Security Operations【6:Chapter 14†CompTIA Security+ Study Guide】.

Comprehensive and Detailed Explanation From Exact Extract:

Infrastructure as Code (IaC) is the technology required for automating infrastructure deployment. IaC allows organizations to define and deploy servers, networks, containers, and cloud resources using machine-readable configuration files rather than manual configuration. This leads to faster deployment, consistent environments, repeatability, version control, and lower human error.

CompTIA Security+ SY0-701 highlights IaC as a foundational component of DevOps and modern cloud operations. It supports automated provisioning through tools such as Terraform, Ansible, CloudFormation, and Puppet. IaC also enhances security by enabling automated compliance checks and standardized hardened configurations.

IaaS (B) is a cloud service model, not an automation mechanism. IoC (C) refers to Indicators of Compromise used in threat intelligence. IoT (D) refers to Internet-connected devices and is unrelated to infrastructure deployment.

Therefore, IaC is the required technology for automated, repeatable, secure infrastructure deployments.

An insider threat is a security risk that originates from within the organization, such as an employee, contractor, or business partner, who has authorized access to the organization’s data and systems. An insider threat can be malicious, such as stealing, leaking, or sabotaging sensitive data, or unintentional, such as falling victim to phishing or social engineering. An insider threat can cause significant damage to the organization’s reputation, finances, operations, and legal compliance. The user’s activity of logging in remotely after hours and copying large amounts of data to a personal device is an example of a malicious insider threat, as it violates the organization’s security policies and compromises the confidentiality and integrity of the data. References = Insider Threats – CompTIA Security+ SY0-701: 3.2, video at 0:00; CompTIA Security+ SY0-701 Certification Study Guide, page 133.

Detailed Explanation:SSH tunneling can secure the unencrypted protocol by encapsulating traffic in an encrypted tunnel. Segmentation isolates the legacy system, reducing the risk of unauthorized access. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Threats, Section: "Compensating Controls for Legacy Systems"​​.

Posting hashes allows users to verify the integrity of downloaded files. As outlined in Security+ SY0-701, a cryptographic hash (e.g., SHA-256) produces a fixed-length digest unique to the file’s contents. Users can compute the hash of the downloaded file and compare it to the published value; a match confirms the file has not been altered.

Certificates (B) establish identity and trust but do not directly verify file integrity post-download unless combined with signing workflows. Algorithms (C) are general methods, not verification artifacts. Salting (D) is used with password hashing and is irrelevant here.

Therefore, A: Hashes is the correct choice.

Monolithic code architecture significantly limits an organization’s ability to benefit from containerization. Containers are designed to package and run small, modular, loosely coupled services, often following a microservices architecture. CompTIA Security+ SY0-701 explains that containers enhance security by reducing attack surface, improving isolation, and allowing granular patching—but only when applications are designed to support this model.

Monolithic applications bundle all components (UI, business logic, database access) into a single large codebase. This makes it difficult to isolate functions into separate containers, apply least privilege, or patch individual components without redeploying the entire application. As a result, security improvements such as rapid updates, minimal images, and fine-grained access controls are harder to achieve.

Regulatory compliance (A) may add requirements but does not inherently block container use. Patch availability (B) affects maintenance but not architecture suitability. Kernel version (C) can be a constraint, but modern container platforms manage kernel compatibility effectively.

Because containers are best suited for modular applications, monolithic code is the primary limitation, making D the correct answer.

Placing a false (decoy) text file in a sensitive location (such as /docs/salaries) is an example of a honeytoken or deception technique. This technique is used to attract insider attackers and monitor their actions when they attempt to access the file.

When encrypting data, two fundamental drivers of cryptographic strength are the algorithm you choose and the key length you use (which affects brute-force feasibility and overall security margin). The Study Guide emphasizes algorithm selection as a best practice: “First, choose your encryption system wisely… Choose an encryption system with an algorithm in the public domain that has been thoroughly vetted by industry experts.” It then highlights key selection/size as another central decision: “You must also select your keys in an appropriate manner. Use a key length that balances your security requirements with performance considerations.”

These two choices directly affect whether encryption meaningfully protects confidentiality. By contrast, obfuscation, masking, and tokenization are different data-protection techniques (often used to reduce exposure or de-identify data) rather than core encryption-strength parameters. Salting is primarily associated with strengthening password hashing (defending against rainbow table attacks), not selecting encryption primitives/strength for general data encryption. Therefore, the best two considerations in the context of encryption itself are Algorithms and Key length.

The Common Vulnerability Scoring System (CVSS) is a standardized framework for assessing the severity of security vulnerabilities. It helps organizations prioritize vulnerability patching by providing a numerical score that reflects the potential impact and exploitability of a vulnerability. CVSS scores are used to gauge the urgency of patching vulnerabilities within a company’s IT environment.

Input validation (D)is the most effective way to preventinjection attacks, such asSQL injection, XSS, etc. It ensures that only correctly formatted and expected inputs are processed by the application.

This is clearly identified underDomain 2.3: Application security techniques, whereinput validationis listed as aprimary defense against injection attacks.

An insider threat is a type of attack that originates from someone who has legitimate access to an organization’s network, systems, or data. In this case, the domain user who encrypted the files on the database server is an example of an insider threat, as they abused their access privileges to cause harm to the organization. Insider threats can be motivated by various factors, such as financial gain, revenge, espionage, or sabotage.

Detailed Explanation:Avoidance involves choosing not to engage in activities or markets where certain risks are present. This is a proactive approach to risk management. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Risk Management Strategies"​​.

Container image hardening best practices include removing default or unnecessary applications (A) to reduce the attack surface and disabling insecure protocols like Telnet (C) to prevent exploitation. Minimizing software components reduces vulnerabilities and limits potential exploits.

Installing a Network Intrusion Prevention System (NIPS) (B) is a network security measure, not typically embedded in a container image. Reconfiguring DNS (D), adding an SFTP server (E), or deleting public certificates (F) are unrelated or could disrupt container functionality.

These practices are part of securing containerized environments covered under Security Architecture topics in SY0-701【6:Chapter 10†CompTIA Security+ Study Guide】.

LDAP authentication on the printer (C)would require users toauthenticate before printing, enablingsecure print release. This ensures that documents arenot printed until the authorized user is physically present, which directly addresses the issue of missing confidential documents.

As perCompTIA Security+ SY0-701, Domain 3.1 (Access management), integratingauthentication mechanisms like LDAPimproves physical and document security in shared environments.

Comprehensive and Detailed In-Depth Explanation:

AnEndpoint Detection and Response (EDR)solution is designed tomonitor, detect, and respond to security incidents on endpoints (such as workstations and servers). Itcollects and analyzes data, detecting suspicious activity and forwarding relevant information for further investigation.

Network Access Control (NAC) (A)enforces network access policies but does not analyze security threats on hosts.

Intrusion Prevention Systems (IPS) (B)detect and block network threats but do not provide deep endpoint analytics.

Security Information and Event Management (SIEM) (C)aggregates logs and provides security analytics but lacks direct endpoint detection and response capabilities.

EDR is the best choicefor analyzing and responding to endpoint security incidents.

A security awareness program is a set of activities and initiatives that aim to educate and inform the users and employees of an organization about the security policies, procedures, and best practices. A security awareness program can help to reduce the human factor in security risks, such as social engineering, phishing, malware, data breaches, and insider threats. A security awareness program should include various elements of communication, such as newsletters, posters, videos, webinars, quizzes, games, simulations, and feedback mechanisms, to deliver the security messages and reinforce the security culture. One of the most likely elements of communication to be included in a security awareness program is reporting phishing attempts or other suspicious activities, as this can help to raise the awareness of the users and employees about the common types of cyberattacks and how to respond to them. Reporting phishing attempts or other suspicious activities can also help to alert the security team and enable them to take appropriate actions to prevent or mitigate the impact of the attacks. Therefore, this is the best answer among the given options.

The other options are not as likely to be included as elements of communication in a security awareness program, because they are either technical or operational tasks that are not directly related to the security awareness of the users and employees. Detecting insider threats using anomalous behavior recognition is a technical task that involves using security tools or systems to monitor and analyze the activities and behaviors of the users and employees and identify any deviations or anomalies that may indicate malicious or unauthorized actions. This task is usually performed by the security team or the security operations center, and it does not require the communication or participation of the users and employees. Verifying information when modifying wire transfer data is an operational task that involves using verification methods, such as phone calls, emails, or digital signatures, to confirm the authenticity and accuracy of the information related to wire transfers, such as the account number, the amount, or the recipient. This task is usually performed by the financial or accounting department, and it does not involve the security awareness of the users and employees. Performing social engineering as part of third-party penetration testing is a technical task that involves using deception or manipulation techniques, such as phishing, vishing, or impersonation, to test the security posture and the vulnerability of the users and employees to social engineering attacks. This task is usuallyperformed by external security professionals or consultants, and it does not require the communication or consent of the users and employees. Therefore, these options are not the best answer for this question. References = Security Awareness and Training – CompTIA Security+ SY0-701: 5.2, video at 0:00; CompTIA Security+ SY0-701 Certification Study Guide, page 263.

Hashing (C)is aone-way cryptographic functionthat produces afixed-length digestrepresenting the original data. If the file changes—even by one bit—the hash will change, making it ideal for verifyingdata integrity.

While encryption protectsconfidentiality, and masking/obfuscation protectdata visibility, onlyhashing ensures integrity.

When conducting a forensic analysis after an incident, it's essential to prioritize the data collection process based on the "order of volatility." This principle dictates that more volatile data (e.g., data in memory, network connections) should be captured before less volatile data (e.g., disk drives, logs). The idea is to preserve the most transient and potentially valuable evidence first, as it is more likely to be lost or altered quickly.

Mean Time To Repair (MTTR) is a key metric used to estimate the average time required to repair a failed component or system and restore it to operational status. In this case, the administrator would rely on MTTR to estimate how long it will take to fix the critical server’s failed drive and get it back online.

Mean Time Between Failures (MTBF) measures the expected operational lifespan between failures, so it does not provide an estimate of repair time.

Recovery Time Objective (RTO) refers to the maximum allowable downtime for a system or service before unacceptable impact occurs, which is a planning metric rather than an actual repair time measure.

Recovery Point Objective (RPO) defines the maximum acceptable data loss measured in time and relates to backup frequency rather than repair duration.

Therefore, MTTR is the appropriate metric to estimate the time to fix a failed drive. This concept is detailed in the Resilience and Physical Security chapter within the Security Operations domain of the SY0-701 exam【6:Chapter 9†CompTIA Security+ Study Guide】

 A nation-state is a threat actor that is sponsored by a government or a political entity to conduct cyberattacks against other countries or organizations. Nation-states have large financial resources, advanced technical skills, and strategic objectives that may target critical systems such as military, energy, or infrastructure. Nation-states are often motivated by espionage, sabotage, or warfare12. References = 1: CompTIA Security+ SY0-701 Certification Study Guide, page 542: Threat Actors – CompTIA Security+ SY0-701 – 2.1, video by Professor Messer.

PCI DSS is the Payment Card Industry Data Security Standard, which is a set of security requirements for organizations that store, process, or transmit cardholder data. PCI DSS aims to protect the confidentiality, integrity, and availability of cardholder data and prevent fraud, identity theft, and data breaches. PCI DSS is enforced by the payment card brands, such as Visa, Mastercard, American Express, Discover, and JCB, and applies to all entities involved in the payment card ecosystem, such as merchants, acquirers, issuers, processors, service providers, and payment applications.

If a large bank fails an internal PCI DSS compliance assessment, the most likely outcome is that the bank will face fines from the payment card brands. An internal PCI DSS compliance assessment is a self-assessment that the bank performs to evaluate its own compliance with the PCI DSS requirements. The bank must submit the results of the internal assessment to the payment card brands or their designated agents, such as acquirers or qualified security assessors (QSAs). If the internal assessment reveals that the bank is not compliant with the PCI DSS requirements, the payment card brands may impose fines on the bank as a penalty for violating the PCI DSS contract. The amount and frequency of the fines may vary depending on the severity and duration of the non-compliance, the number and type of cardholder data compromised, and the level of cooperation and remediation from the bank. The fines can range from thousands to millions of dollars per month, and can increase over time if the non-compliance is not resolved.

The other options are not correct because they are not the most likely outcomes if a large bank fails an internal PCI DSS compliance assessment. B. Audit findings. Audit findings are the results of an external PCI DSS compliance assessment that is performed by a QSA or an approved scanning vendor (ASV). An external assessment is required for certain entities that handle a large volume of cardholder data or have a history of non-compliance. An external assessment may also be triggered by a security incident or a request from the payment card brands. Audit findings may reveal the gaps and weaknesses in the bank’s security controls andrecommend corrective actions to achieve compliance. However, audit findings are not the outcome of an internal assessment, which is performed by the bank itself. C. Sanctions. Sanctions are the measures that the payment card brands may take against the bank if the bank fails to pay the fines or comply with the PCI DSS requirements. Sanctions may include increasing the fines, suspending or terminating the bank’s ability to accept or process payment cards, or revoking the bank’s PCI DSS certification. Sanctions are not the immediate outcome of an internal assessment, but rather the possible consequence of prolonged or repeated non-compliance. D. Reputation damage. Reputation damage is the loss of trust and credibility that the bank may suffer from its customers, partners, regulators, and the public if the bank fails an internal PCI DSS compliance assessment. Reputation damage may affect the bank’s brand image, customer loyalty, market share, and profitability. Reputation damage is not a direct outcome of an internal assessment, but rather a potential risk that the bank may face if the non-compliance is exposed or exploited by malicious actors. References = CompTIA Security+ Study Guide (SY0-701), Chapter 8: Governance, Risk, and Compliance, page 388. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 8.2: Compliance and Controls, video: PCI DSS (5:12). PCI Security Standards Council, PCI DSS Quick Reference Guide, page 4. PCI Security Standards Council, PCI DSS FAQs, question 8. PCI Security Standards Council, PCI DSS FAQs, question 9.

Masking is a method to secure credit card data that involves replacing some or all of the digits with symbols, such as asterisks, dashes, or Xs, while leaving some of the original digits visible. Masking is best to use when a requirement is to see only the last four numbers on a credit card, as it can prevent unauthorized access to the full card number, while still allowing identification and verification of the cardholder. Masking does not alter the original data, unlike encryption, hashing, or tokenization, which use algorithms to transform the data into different formats.

SCAP (Security Content Automation Protocol) is designed to automate vulnerability management, configuration assessment, and compliance checking. According to CompTIA Security+ SY0-701, SCAP standardizes how vulnerability information is expressed, measured, and shared, allowing security tools to automatically scan systems, identify weaknesses, and assess compliance against predefined baselines.

SCAP integrates multiple standards such as CVE, CVSS, CPE, and XCCDF, enabling automated vulnerability scanning, scoring, and reporting across large environments. This makes it a core technology for continuous vulnerability management and compliance automation.

CVE (A) is a catalog of known vulnerabilities, not an automation framework. OSINT (C) provides publicly available intelligence but does not automate remediation or assessment. CVSS (D) provides severity scoring but does not automate vulnerability management.

Because SCAP enables automated identification, assessment, and reporting of vulnerabilities, the correct answer is B: SCAP.

The document described in the question is a Disaster Recovery Plan (DRP). A DRP outlines the process and procedures for restoring critical systems and operations after a major disruption or outage. It includes the order in which systems should be brought back online to ensure minimal impact on business operations, prioritizing the most critical systems to recover first.

Detective controls are security measures that are designed to identify and monitor any malicious activity or anomalies on a system or network. They can help to discover the source, scope, and impact of an attack, and provide evidence for further analysis or investigation. Detective controls include log files, security audits, intrusion detection systems, network monitoring tools, andantivirus software. In this case, the administrator used log files as a detective control to review the ransomware attack on the company’s system. Log files are records of events and activities that occur on a system or network, such as user actions, system errors, network traffic, and security alerts. They can provide valuable information for troubleshooting, auditing, and forensics.

The first step in creating an anomaly detection process is building a baseline of normal behavior within the system. This baseline serves as a reference point to identify deviations or anomalies that could indicate a security incident. By understanding what normal activity looks like, security teams can more effectively detect and respond to suspicious behavior.

A directive managerial control provides guidance and expectations for behavior through policy and governance. An Acceptable Use Policy (AUP) is a classic example, as it defines how users may and may not use organizational systems and data. Security+ SY0-701 categorizes policies as managerial (administrative) controls that direct user behavior and establish accountability.

A login warning banner (B) is typically a deterrent/administrative control but is not managerial in nature. A master service agreement (C) is a contractual/legal document, not a managerial directive for internal users. A “No trespassing” sign (D) is a physical deterrent control.

Because an AUP formally directs behavior and is enforced through management processes, A: Acceptable use policy is correct.

Detailed Explanation:The Common Vulnerability Scoring System (CVSS) is a standardized metric used to assess the severity of vulnerabilities, aiding organizations in prioritizing their response based on risk. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 2: Vulnerabilities, Section: "Vulnerability Prioritization and Metrics"​​.

Part 2:

Smishing is a type of social engineering technique that uses text messages (SMS) to trick victims into revealing sensitive information, clicking malicious links, or downloading malware. Smishing messages often appear to come from legitimate sources, such as banks, government agencies, or service providers, and use urgent or threatening language to persuade the recipients to take action12. In this scenario, the text message that claims to be from the payroll department is an example of smishing.

Impersonation is a type of social engineering technique that involves pretending to be someone else, such as an authority figure, a trusted person, or a colleague, to gain the trust or cooperation of the target. Impersonation can be done through various channels, such as phone calls, emails, text messages, or in-person visits, and can be used to obtain information, access, or money from the victim34. In this scenario, the text message that pretends to be from the payroll department is an example of impersonation.

A. Typosquatting is a type of cyberattack that involves registering domain names that are similar to popular or well-known websites, but with intentional spelling errors or different extensions. Typosquatting aims to exploit the common mistakes that users make when typingweb addresses, and redirect them to malicious or fraudulent sites that may steal their information, install malware, or display ads56. Typosquatting is not related to text messages or credential verification.

B. Phishing is a type of social engineering technique that uses fraudulent emails to trick recipients into revealing sensitive information, clicking malicious links, or downloading malware. Phishing emails often mimic the appearance and tone of legitimate organizations, such as banks, retailers, or service providers, and use deceptive or urgent language to persuade the recipients to take action78. Phishing is not related to text messages or credential verification.

D. Vishing is a type of social engineering technique that uses voice calls to trick victims into revealing sensitive information, such as passwords, credit card numbers, or bank account details. Vishing calls often appear to come from legitimate sources, such as law enforcement, government agencies, or technical support, and use scare tactics or false promises to persuade the recipients to comply9 . Vishing is not related to text messages or credential verification.

F. Misinformation is a type of social engineering technique that involves spreading false or misleading information to influence the beliefs, opinions, or actions of the target. Misinformation can be used to manipulate public perception, create confusion, damage reputation, or promote an agenda . Misinformation is not related to text messages or credential verification.

Environmental variables store configuration settings, paths, and other system-related information that applications and processes use. If an attacker gains access to these variables, they could manipulate them to alter application behavior, gain unauthorized access, or escalate privileges.For example, an attacker could modify the PATH variable to execute malicious programs instead of legitimate ones. This can significantlyincrease the scope and impact of an exploited vulnerability, making it a major security concern.

The misuse of personally identifiable information (PII) is often mitigated through employee training on privacy legislation and company compliance. Training on privacy legislation educates employees about legal requirements and consequences related to handling PII, such as GDPR or HIPAA. Company compliance training reinforces internal policies and procedures regarding data handling, acceptable use, and the repercussions of violations.

While social engineering and phishing training are important for security awareness, they address external threats rather than insider misuse of data. Risk management is a broader discipline focused on assessing and mitigating organizational risks but does not directly prevent employee misuse through training. Remote work training focuses on secure practices for working outside corporate environments, which is not the core issue here.

This approach aligns with Security Program Management and Oversight principles emphasizing compliance and privacy training to reduce insider threats【6:Chapter 16†CompTIA Security+ Study Guide】.

To limit the potential impact on the log-in database in case of a breach, the security team would most likely recommend hashing. Hashing converts passwords into fixed-length strings of characters, which cannot be easily reversed to reveal the original passwords. Even if the database is breached, attackers cannot easily retrieve the actual passwords if they are properly hashed (especially with techniques like salting).

Tokenization is used to replace sensitive data with a token, but it is more common for protecting credit card data than passwords.

Obfuscation is the process of making data harder to interpret but is weaker than hashing for password protection.

Segmentation helps isolate data but doesn't directly protect the contents of the login database​​.

Comprehensive and Detailed In-Depth Explanation:

Theright to be forgotten, as outlined in regulations such as theGeneral Data Protection Regulation (GDPR), requires organizations topermanently delete an individual's personal dataupon request, unless there is a legal or contractual obligation to retain it.

Purging personally identifiable attributes (A)removes some identifying data but does not fully satisfy the request.

Encrypting the data (B)does not remove it, and the data is still accessible with the decryption key.

Obfuscating data (D)makes data unreadable but does not permanently remove it.

To comply withthe right to be forgotten, organizations mustremove all of the person's dataunless an exception applies.

The threat actor’s intent is clearly blackmail, a form of extortion where sensitive information is used to coerce an individual into taking an action, usually involving financial gain. In this scenario, the attacker threatens to leak incriminating or compromising photos unless the government official wires a large sum of money. CompTIA Security+ SY0-701 defines blackmail as the use of sensitive or embarrassing information to manipulate or force actions from victims.

This differs from organized crime (A), which focuses on profit-driven cyber operations but typically uses technical attacks such as ransomware, data theft, or fraud rather than anonymous mailed threats. Philosophical beliefs (B) refers to hacktivism, where attackers pursue ideological motives—not present here. Espionage (C) involves intelligence gathering for political or competitive advantage, typically performed by nation-states or advanced persistent threats (APTs).

This scenario aligns directly with extortion-based social engineering, where attackers manipulate victims through fear and emotional pressure. According to Security+ guidance, blackmail often occurs through email, physical mail, or compromised personal data leaks, all fitting this situation. Therefore, the threat actor’s intent is blackmail.

= A jump server is a server that acts as an intermediary between a user and a target system. A jump server can provide an added layer of security by preventing unauthorized access to internal company resources. A user can connect to the jump server using a secure protocol, such as SSH, and then access the target system from the jump server. This way, the target system is isolated from the external network and only accessible through the jump server. A jump server can also enforce security policies, such as authentication, authorization, logging, and auditing, on the user’s connection. A jump server is also known as a bastion host or a jump box. References = CompTIA Security+ Certification Exam Objectives, Domain 3.3: Given a scenario, implement secure network architecture concepts. CompTIA Security+ Study Guide (SY0-701), Chapter 3: Network Architecture and Design, page 101. Other Network Appliances – SY0-601 CompTIA Security+ : 3.3, Video 3:03. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 2.

Shadow IT refers to software, hardware, cloud services, or applications deployed without approval from the IT or security department. In this scenario, a high school department is using an unvetted simulation program—classic Shadow IT behavior.

Security+ SY0-701 explains that Shadow IT:

Introduces unknown vulnerabilities

Bypasses security controls

Creates compliance risks

Leads to data exposure

Interferes with standard configuration management

Espionage (A) involves intelligence gathering, not unauthorized software use. Data exfiltration (B) involves data theft, not unauthorized software deployment. Zero-day (D) refers to unknown vulnerabilities, not unapproved systems.

Thus, Shadow IT is the correct answer.

A buffer overflow is a type of software vulnerability that occurs when an application writes more data to a memory buffer than it can hold, causing the excess data to overwrite adjacent memory locations. This can lead to unexpected behavior, such as crashes, errors, or code execution. A buffer overflow can be exploited by an attacker to inject malicious code or commands into the application, which can compromise the security and functionality of the system. An organization’s internet-facing website was compromised when an attacker exploited a buffer overflow. To best protect against similar attacks in the future, the organization should deploy a web application firewall (WAF). A WAF is a type of firewall that monitors and filters the traffic between a web application and the internet. A WAF can detect and block common web attacks, such as buffer overflows, SQL injections, cross-site scripting (XSS), and more. A WAF can also enforce security policies and rules, such as input validation, output encoding, and encryption. A WAF can provide a layer of protection for the web application, preventing attackers from exploiting its vulnerabilities and compromising its data. References = Buffer Overflows – CompTIA Security+ SY0-701 – 2.3, Web Application Firewalls – CompTIA Security+ SY0-701 – 2.4, [CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition]

Systems that control physical industrial processes—such as pumping gas, water control, electrical grids, or manufacturing lines—fall under SCADA (Supervisory Control and Data Acquisition) environments. SCADA systems are part of larger OT (Operational Technology) infrastructures and manage sensors, actuators, valves, flow controls, and telemetry.

CompTIA Security+ SY0-701 explains that SCADA environments typically:

Use legacy protocols (e.g., Modbus, DNP3)

Require high availability

Often run outdated operating systems

Have control systems that cannot easily be patched

Require specialized segmentation and monitoring

This exactly matches the scenario describing a “specialized legacy platform controlling gas flow inside pipes.”

IaaS (A) is cloud infrastructure and unrelated to industrial control. SDN (C) relates to software-defined networking, not physical industrial controls. IoT (D) includes smart devices but is not typically used for large-scale industrial gas control.

Thus, securing SCADA is the correct answer.

Zero Trust architecture is based on the principle of "never trust, always verify," meaning all traffic between systems must be authenticated and authorized before communication is allowed, regardless of network location.

Policy enforcement (A) is important but broader. Authentication (B) is a component of Zero Trust, and confidentiality (D) refers to data protection, not access validation.

Zero Trust is a modern security framework emphasized in Security Architecture for securing enterprise environments【6:Chapter 3†CompTIA Security+ Study Guide】.

Business email compromise (BEC) is a type of targeted phishing attack where an attacker gains access to a legitimate business email account (or convincingly impersonates one) to manipulate financial transactions, such as redirecting payments to a fraudulent bank account. The scenario described matches this pattern.

Acknowledgement and attestationinvolveformal confirmationthat an application is no longer in scope for compliance, auditing, or reporting requirements. This typically includes documentation signed by relevant stakeholders confirming that the software no longer processes, stores, or transmits relevant data.

Data inventory and retention (A)is related to managing data assets, not software scope confirmation.

Right to be forgotten (B)pertains toprivacy laws (e.g., GDPR), allowing individuals to request data deletion.

Due care and due diligence (C)focus on security best practices rather than software applicability.

Aconflict of interest (B)arises when personal relationships or interests could potentially influence professional decisions. In this case, the CFO's friendship with the vendor could improperly affect the procurement decision-making process.

This scenario falls underDomain 5.3: Explain the importance of frameworks, policies, procedures, and controls—specifically under“Personnel policies (e.g., conflict of interest, mandatory vacations, job rotation).”

Rules of engagement are the detailed guidelines and constraints regarding the execution of information security testing, such as penetration testing. They define the scope, objectives, methods, and boundaries of the test, as well as the roles and responsibilities of the testers and the clients. Rules of engagement help to ensure that the test is conducted in a legal, ethical, and professional manner, and that the results are accurate and reliable. Rules of engagement typically include the following elements:

The type and scope of the test, such as black box, white box, or gray box, and the target systems, networks, applications, or data.

The client contact details and the communication channels for reporting issues, incidents, or emergencies during the test.

The testing team credentials and the authorized tools and techniques that they can use.

The sensitive data handling and encryption requirements, such as how to store, transmit, or dispose of any data obtained during the test.

The status meeting and report schedules, formats, and recipients, as well as the confidentiality and non-disclosure agreements for the test results.

The timeline and duration of the test, and the hours of operation and testing windows.

The professional and ethical behavior expectations for the testers, such as avoiding unnecessary damage, disruption, or disclosure of information.

Supply chain analysis, right to audit clause, and due diligence are not related to the terms of a test with a third-party penetration tester. Supply chain analysis is the process of evaluating the security and risk posture of the suppliers and partners in a business network. Right to audit clause is a provision in a contract that gives one party the right to audit another party to verify their compliance with the contract terms and conditions. Due diligence is the process of identifying and addressing the cyber risks that a potential vendor or partner brings to an organization.

Risk appetiterefers to thelevel of risk an organization is willing to acceptbefore implementing security measures. When expanding access controls, the company must assess how much risk is acceptable in terms ofdata exposure, unauthorized access, and compliance obligations.

802.1X is a network access control protocol that provides an authentication mechanism to devices trying to connect to a LAN or WLAN. It supports the use of certificates for authentication, can quarantine unapproved devices, and ensures that only approved and updated devices can access network resources. This protocol best meets the requirements of securing both wired and wireless networks with internal certificates.

Salting is a technique used to enhance the security of hashed passwords by adding a unique, random value (salt) to each password before hashing it. This prevents attackers from easily decrypting passwords using rainbow tables, which are precomputed tables for reversing cryptographic hash functions. Since each password has a unique salt, the same password will produce different hash values, making rainbow table attacks ineffective.

CVSS (Common Vulnerability Scoring System) provides a standardized way to rate the severity of software vulnerabilities. Organizations use CVSS scores to prioritize which vulnerabilities to address first, focusing on those with the highest risk.

To determine whether the connection was successful after a user clicked on a link in a phishing email, the most relevant log source to analyze would be the network logs. These logs would provide information on outbound and inbound traffic, allowing the analyst to see if the user’s system connected to the remote server specified in the phishing link. Network logs can includedetails such as IP addresses, domains accessed, and the success or failure of connections, which are crucial for understanding the impact of the phishing attempt.

Segmentation is a technique that divides a network into smaller subnetworks or segments, each with its own security policies and controls. Segmentation can help mitigate network access vulnerabilities in legacy loT devices by isolating them from other devices and systems, reducing their attack surface and limiting the potential impact of a breach. Segmentation can also improve network performance and efficiency by reducing congestion and traffic. Patching, insurance, and replacement are other possible strategies to deal with network access vulnerabilities, but they may not be feasible or effective in the short term. Patching may not be available or compatible for legacy loT devices, insurance may not cover the costs or damages of a cyberattack, and replacement may be expensive and time-consuming. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 142-143

ARP poisoning(also known as ARP spoofing) is a basicman-in-the-middle (MITM)attack that involves sending fake ARP responses to redirect traffic. This technique isnot sophisticatedand can be easily executed using freely available tools like Cain & Abel, Ettercap, or Wireshark.

Such attacks are often attempted byunskilled attackers (script kiddies)testing their abilities, especially in environments like schools. The term“unskilled attacker”fits best here, as credential stuffing and DMARC are unrelated to ARP poisoning.

Steganography is the process of hiding information within another medium, such as an image, audio, video, or text file. The hidden information is not visible or noticeable to the casual observer, and can only be extracted by using a specific technique or key. Steganography can be used for various purposes, such as concealing secret messages, watermarking, or evading detection by antivirus software12

When a legacy device is no longer receiving updates or patches, it is considered to be at the end of life (EOL). This means the manufacturer has ceased support for the device, and it will no longer receive updates, security patches, or technical assistance. EOL devices pose security risks and are often decommissioned or replaced.

End of support may seem similar but typically refers to the cessation of technical support, whereas EOL means the device is fully retired.

End of business and End of testing do not apply in this context​​.

Mobile Device Management (MDM) solutions can enforce security policies that prevent users from jailbreaking or rooting their devices—that is, from modifying the operating system to remove restrictions and gain unauthorized control. Jailbreaking can introduce significant security risks, so MDM is used to ensure device integrity by preventing users from making these changes.

Availability is the ability of a system or service to be accessible and usable when needed. For a web application that allows individuals to digitally report health emergencies, availability is the most important consideration during development, because any downtime or delay could have serious consequences for the health and safety of the users. The web application should be designed to handle high traffic, prevent denial-of-service attacks, and have backup and recovery plans in case of failures2.

The least privilege principle states that users and processes should only have the minimum level of access required to perform their tasks. This helps to prevent unauthorized or unnecessary actions that could compromise security. In this case, the patch transfer might be failing because the user or process does not have the appropriate permissions to access the critical system or the network resources needed for the transfer. Applying the least privilege principle can help to avoid this issue by granting the user or process the necessary access rights for the patching activity. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 931
