When monitoring APs within a LAN using a Wireless Network Management System (WNMS), what secure protocol may be used by the WNMS to issue configuration changes to APs?
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 security vulnerabilities may result from a lack of staging, change management, and installation procedures for WLAN infrastructure equipment? (Choose 2)
You must locate non-compliant 802.11 devices. Which one of the following tools will you use and why?
Given: WLAN protocol analyzers can read and record many wireless frame parameters.
What parameter is needed to physically locate rogue APs with a protocol analyzer?
After completing the installation of a new overlay WIPS for the purpose of rogue detection and security monitoring at your corporate headquarters, what baseline function MUST be performed in order to identify security threats?
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?
The following numbered items show some of the contents of each of the four frames exchanged during the 4-way handshake:
1. Encrypted GTK sent
2. Confirmation of temporal key installation
3. Anonce sent from authenticator to supplicant
4. Snonce sent from supplicant to authenticator, MIC included
Arrange the frames in the correct sequence beginning with the start of the 4-way handshake.
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?
Given: In a security penetration exercise, a WLAN consultant obtains the WEP key of XYZ Corporation’s wireless network. Demonstrating the vulnerabilities of using WEP, the consultant uses a laptop running a software AP in an attempt to hijack the authorized user’s connections. XYZ’s legacy network is using 802.11n APs with 802.11b, 11g, and 11n client devices.
With this setup, how can the consultant cause all of the authorized clients to establish Layer 2 connectivity with the software access point?
