Certified Wireless Security Professional (CWSP) Questions and Answers
Given: You are the WLAN administrator in your organization and you are required to monitor the network and ensure all active WLANs are providing RSNs. You have a laptop protocol analyzer configured.
In what frame could you see the existence or non-existence of proper RSN configuration parameters for each BSS through the RSN IE?
In an effort to optimize WLAN performance, ABC Company has upgraded their WLAN infrastructure from 802.11a/g to 802.11n. 802.11a/g clients are still supported and are used throughout ABC’s facility. ABC has always been highly security conscious, but due to budget limitations, they have not yet updated their overlay WIPS solution to 802.11n or 802.11ac.
Given ABC’s deployment strategy, what security risks would not be detected by the 802.11a/g WIPS?
For a WIPS system to identify the location of a rogue WLAN device using location patterning (RF fingerprinting), what must be done as part of the WIPS installation?
What security vulnerabilities may result from a lack of staging, change management, and installation procedures for WLAN infrastructure equipment? (Choose 2)
You have been recently hired as the wireless network administrator for an organization spread across seven locations. They have deployed more than 100 APs, but they have not been managed in either an automated or manual process for more than 18 months. Given this length of time, what is one of the first things you should evaluate from a security perspective?
Select the answer option that arranges the numbered events in the correct time sequence (first to last) for a client associating to a BSS using EAP-PEAPv0/MSCHAPv2.
1. Installation of PTK
2. Initiation of 4-way handshake
3. Open system authentication
4. 802.11 association
5. 802.1X controlled port is opened for data traffic
6. Client validates server certificate
7. AS validates client credentials
Given: Mary has just finished troubleshooting an 802.11g network performance problem using a laptop-based WLAN protocol analyzer. The wireless network implements 802.1X/PEAP and the client devices are authenticating properly. When Mary disables the WLAN protocol analyzer, configures her laptop for PEAP authentication, and then tries to connect to the wireless network, she is unsuccessful. Before using the WLAN protocol analyzer, Mary’s laptop connected to the network without any problems.
What statement indicates why Mary cannot access the network from her laptop computer?
What attack cannot be detected by a Wireless Intrusion Prevention System (WIPS)?
Your organization required compliance reporting and forensics features in relation to the 802.11ac WLAN they have recently installed. These features are not built into the management system provided by the WLAN vendor. The existing WLAN is managed through a centralized management console provided by the AP vendor with distributed APs and multiple WLAN controllers configured through this console.
What kind of system should be installed to provide the required compliance reporting and forensics features?
In what deployment scenarios would it be desirable to enable peer-to-peer traffic blocking?
As the primary security engineer for a large corporate network, you have been asked to author a new security policy for the wireless network. While most client devices support 802.1X authentication, some legacy devices still only support passphrase/PSK-based security methods.
When writing the 802.11 security policy, what password-related items should be addressed?
Given: ABC Hospital wishes to create a strong security policy as a first step in securing their 802.11 WLAN.
Before creating the WLAN security policy, what should you ensure you possess?
What policy would help mitigate the impact of peer-to-peer attacks against wireless-enabled corporate laptop computers when the laptops are also used on public access networks such as wireless hot-spots?
What elements should be addressed by a WLAN security policy? (Choose 2)
As a part of a large organization’s security policy, how should a wireless security professional address the problem of rogue access points?
Given: ABC Corporation is evaluating the security solution for their existing WLAN. Two of their supported solutions include a PPTP VPN and 802.1X/LEAP. They have used PPTP VPNs because of their wide support in server and desktop operating systems. While both PPTP and LEAP adhere to the minimum requirements of the corporate security policy, some individuals have raised concerns about MS-CHAPv2 (and similar) authentication and the known fact that MS-CHAPv2 has proven vulnerable in improper implementations.
As a consultant, what do you tell ABC Corporation about implementing MS-CHAPv2 authentication? (Choose 2)
What is a primary criteria for a network to qualify as a Robust Security Network (RSN)?
An attack is under way on the network. The attack is preventing users from accessing resources required for business operations, but the attacker has not gained access to any files or data. What kind of attack is described?
What statement is true regarding the nonces (ANonce and SNonce) used in the IEEE 802.11 4 Way Handshake?
Which one of the following describes the correct hierarchy of 802.1X authentication key derivation?
When using the 802.1X/EAP framework for authentication in 802.11 WLANs, why is the 802.1X Controlled Port still blocked after the 802.1X/EAP framework has completed successfully?
Given: An 802.1X/EAP implementation includes an Active Directory domain controller running Windows Server 2012 and an AP from a major vendor. A Linux server is running RADIUS and it queries the domain controller for user credentials. A Windows client is accessing the network.
What device functions as the EAP Supplicant?
You must support a TSN as you have older wireless equipment that will not support the required processing of AES encryption. Which one of the following technologies will you use on the network so that a TSN can be implemented that would not be required in a network compliant with 802.11-2012 non-deprecated technologies?
What protocols allow a network administrator to securely manage the configuration of WLAN controllers and access points? (Choose 2)
Given: Your network implements an 802.1X/EAP-based wireless security solution. A WLAN controller is installed and manages seven APs. FreeRADIUS is used for the RADIUS server and is installed on a dedicated server named SRV21. One example client is a MacBook Pro with 8 GB RAM.
What device functions as the 802.1X/EAP Authenticator?
Given: ABC Company has a WLAN controller using WPA2-Enterprise with PEAPv0/MS-CHAPv2 and AES-CCMP to secure their corporate wireless data. They wish to implement a guest WLAN for guest users to have Internet access, but want to implement some security controls. The security requirements for the hot-spot include:
