Given: You are using a Wireless Aggregator utility to combine multiple packet captures. One capture exists for each of channels 1, 6 and 11.
What kind of troubleshooting are you likely performing with such a tool?
What WLAN client device behavior is exploited by an attacker during a hijacking attack?
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?
You perform a protocol capture using Wireshark and a compatible 802.11 adapter in Linux. When viewing the capture, you see an auth req frame and an auth rsp frame. Then you see an assoc req frame and an assoc rsp frame. Shortly after, you see DHCP communications and then ISAKMP protocol packets.
What security solution is represented?
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 individualshave 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)
Given: John Smith uses a coffee shop's Internet hot-spot (no authentication or encryption) to transfer funds between his checking and savings accounts at his bank's website. The bank's website uses the HTTPS protocol to protect sensitive account information. While John was using the hot-spot, a hacker was able to obtain John's bank account user ID and password and exploit this information.
What likely scenario could have allowed the hacker to obtain John's bank account user ID and password?
Given: You manage a wireless network that services 200 wireless users. Your facility requires 20 access points, and you have installed an IEEE 802.11-compliant implementation of 802.1X/LEAP with AES-CCMP as an authentication and encryption solution.
In this configuration, the wireless network is initially susceptible to what type of attacks? (Choose 2)
What 802.11 WLAN security problem is directly addressed by mutual authentication?
Given: You have a Windows laptop computer with an integrated, dual-band, Wi-Fi compliant adapter. Your laptop computer has protocol analyzer software installed that is capable of capturing and decoding
802.11ac data.
What statement best describes the likely ability to capture 802.11ac frames for security testing purposes?
ABC Company uses the wireless network for highly sensitive network traffic. For that reason, they intend to protect their network in all possible ways. They are continually researching new network threats and new preventative measures. They are interested in the security benefits of 802.11w, but would like to know its limitations.
What types of wireless attacks are protected by 802.11w? (Choose 2)
