Cisco 300-740 Dumps

Rule 1 is a “deny all” rule placed at the top of the access control policy. Because Cisco firewalls process rules sequentially from top to bottom, Rule 1 is blocking all traffic—including RDP (Rule 2) and HTTPS (Rule 3). To allow specific traffic, the “deny all” catch-all rule should be placed last so that the specific allow rules are evaluated first.

SCAZT Section 3 (Network and Cloud Security, Pages 69–74) discusses rule hierarchy and clearly states that allow rules must precede any general deny policies to ensure intended traffic is matched correctly. This best practice is essential when dealing with multi-cloud access control.

The Secure Cloud Analytics alert indicates suspicious heartbeat-based connections from an internal server (ip-10-201-0-16) to multiple suspicious IPs over UDP/port 53 (DNS). This behavior suggests command-and-control (C2) activity or botnet communications.

B: Alerting the incident response (IR) team is a critical next step in escalating a verified threat as per SCAZT Section 6 (Threat Response, Pages 114–117).

D: Blocking the identified malicious IPs on perimeter firewalls or network access control devices is an appropriate containment step to disrupt communication.

Reinstallation (A/E) is premature without a full forensic investigation. Validating IDS logs (C) is useful but not immediate response-focused compared to actions B and D.

In IKEv1 policy configuration for Cisco ASA, two key commands are required to define the encryption and hashing algorithms:

A: encryption aes-256 defines the encryption method for the IKE SA.

E: hash sha-256 ensures SHA-256 is used as the integrity mechanism during IKE phase 1.

According to Cisco documentation and SCAZT (Section 1: Cloud Security Architecture, Pages 19–22), these two components are essential to negotiating a secure VPN tunnel. The provided config uses group 1 (modp768), which is weak by today’s standards and could also lead to negotiation failure. However, from the available options, encryption and hash are the two required for tunnel success.

The flow data in the exhibit shows multiple short-duration, high-volume HTTPS connections (443/TCP) from IP 10.10.10.10 to multiple destination IPs in the 50.10.10.0/24 network. All flows are 22 seconds long and transfer exactly 1.77M of data. This uniform behavior to a large set of IP addresses strongly indicates a Denial of Service (DoS) pattern, where an internal host (10.10.10.10) is overwhelming external systems in the 50.10.10.0/24 range.

The SCAZT guide (Section 6: Threat Response, Pages 114–117) explains how Secure Cloud Analytics uses NetFlow and behavioral modeling to identify such volumetric threats. Key identifiers include:

Same connection size (1.77M)

Multiple unique peer IPs in a single external subnet

Same destination port and protocol (HTTPS)

Zero TCP connections completed, indicating unacknowledged connections

This matches the behavioral pattern of a DoS originating from an internal host.

The screenshot from Cisco Secure Cloud Analytics shows a Role Violation alert. According to the “Supporting Observations” pane, the device with IP 10.201.0.15 is assigned the role of Domain Controller but has demonstrated traffic behavior matching an FTP client, connecting to ports 20, 21, 115, 152, 989, and 990. This discrepancy triggered the alert.

Cisco SCAZT documentation emphasizes that devices acting outside their expected network roles (e.g., a domain controller acting as an FTP client) indicate potential compromise or misuse. Role-based anomaly detection is part of Visibility and Assurance mechanisms where baseline behaviors are continuously monitored and flagged when changes occur outside expected policy or operational norms.

After Cloudlock is integrated with Salesforce, full visibility into objects and data requires that Cloudlock has the “View All Data” permission enabled on the connected Salesforce account. This permission allows the Cloudlock API connection to access all user data, regardless of individual field-level or sharing rules. Without it, Cloudlock will be limited in its visibility scope.

As per SCAZT (Section 4: Application and Data Security, Pages 86–89), integration with SaaS platforms like Salesforce must include enabling comprehensive data visibility to perform effective risk analysis and policy enforcement.

MITRE ATT&CK is a globally accessible knowledge base that catalogs adversarial tactics and techniques based on real-world observations. According to SCAZT Section 6: Threat Response (Page 113), this framework enables security professionals to map and anticipate adversarial behavior throughout the attack lifecycle. It supports threat modeling, detection engineering, and incident response.

In Cisco ASA configurations using IKEv2, the integrity command defines the hash algorithm. To use SHA-512, the correct syntax is:

integrity sha512

Without this, the IKEv2 proposal is considered incomplete or mismatched with the peer. The encryption command sets encryption (AES-256, etc.), not hashing. The correct structure is:

crypto ikev2 policy <#>

encryption aes-256

integrity sha512

group 2

prf sha512

lifetime 86400

The exhibit shows DNS Block as the reason and lists 10.1.108.100 as the Responder IP, with the Initiator being 10.1.113.7. In Cisco Secure Firewall Management Center reports, the “Initiator IP” is the source of the request and the “Responder IP” is the source of the response. Since the DNS security intelligence engine flagged the traffic, and 10.1.108.100 was the responder, the blocked traffic corresponds to a DNS response from that IP.

The anyconnect keep-installer none command is used to remove the Cisco Secure Client (formerly AnyConnect) from an endpoint once the VPN session ends. This is useful in temporary or kiosk-based access environments. The default behavior retains the client.

This capability is covered in SCAZT Section 2: User and Device Security (Pages 40–44), which outlines VPN session lifecycle management and Secure Client policies.

The Cisco SAFE architecture uses the concept of Secure Domains as foundational blocks. These domains represent areas of the network (e.g., Branch, Data Center, Cloud, Edge) that require specific security controls. Each domain aligns with controls across visibility, segmentation, threat protection, and identity services.

The MITRE ATT&CK framework is a globally recognized knowledge base that catalogs adversary behavior. One of its most crucial components is its matrix of Tactics and Techniques.

“Techniques for accessing credentials” is a key example of the Techniques layer within the MITRE ATT&CK matrix.

These techniques describe how adversaries achieve tactical objectives—such as gaining access to credentials for lateral movement or privilege escalation.

In the SCAZT guide under Threat Response, organizations are advised to map telemetry and detection tools (like Cisco Secure Analytics, SecureX, and Secure Endpoint) to the MITRE ATT&CK framework to enhance visibility and accelerate threat response.

To enforce both user-based and device-based authentication on Cisco ASA, the tunnel group must include the command: authentication aaa certificate. This configuration requires that both a valid username/password (authenticated via AAA, such as Active Directory) and a trusted certificate (device identity) are present before allowing VPN access. Without this directive, only username/password credentials are validated, which leads to the scenario described in the question.

According to the SCAZT documentation, web application firewalls (WAFs) designed to protect against zero-day Distributed Denial of Service (DDoS) attacks leverage adaptive and behavioral-based algorithms. These algorithms dynamically analyze traffic patterns, baseline normal behavior, and detect anomalies that could indicate novel or zero-day attacks. Unlike signature-based detection, adaptive and behavioral methods adjust in real-time to emerging threats, learning from ongoing traffic without relying on pre-defined rules. This proactive approach enables rapid detection and mitigation of unknown DDoS vectors, critical for cloud and network security where threats evolve constantly.

To preserve the user for investigation while immediately revoking access, the correct approach is to disable the user in the Duo Admin Panel. This action blocks authentication without deleting logs or user data. Simultaneously, resetting the password from Active Directory ensures any potentially compromised credentials are revoked.

According to SCAZT (Section 2: User and Device Security, Pages 40–44), disabling user accounts in Duo offers secure containment during security incidents while maintaining data for forensic review.

Directory traversal attacks exploit improper file path validations to access unauthorized directories and files. To prevent this, it is critical to restrict what areas of the file system an application or user can access. Limiting file system permissions prevents attackers from gaining access to sensitive areas even if a traversal vulnerability exists.

As explained in SCAZT Section 4 (Application and Data Security, Pages 85–87), enforcing minimal privileges and file system segmentation is a key defense against such attacks.

In the provided screenshot of Cisco Secure Firewall Management Center (FMC), the rule labeled "Block Facebook" is intended to block access to Facebook and Facebook Apps. However, the rule lacks correct zone configurations, which is why the block is ineffective.

Per Cisco's best practices outlined in the Designing and Implementing Secure Cloud Access for Users and Endpoints (SCAZT) documentation and Cisco Secure Firewall documentation:

The source zone should reflect where the traffic is originating from—in this case, from internal users. Therefore, Source Zone must be set to inside (Answer: E).

The destination zone should reflect where the traffic is headed—in this case, towards the internet. So, Destination Zone must be set to outside (Answer: D).

Without properly defining source and destination zones, FMC rules may not match the traffic correctly, resulting in traffic being incorrectly allowed.
