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: 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?
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?
You have an AP implemented that functions only using 802.11-2012 standard methods for the WLAN communications on the RF side and implementing multiple SSIDs and profiles on the management side configured as follows:
1. SSID: Guest – VLAN 90 – Security: Open with captive portal authentication – 2 current clients
2. SSID: ABCData – VLAN 10 – Security: PEAPv0/EAP-MSCHAPv2 with AES-CCMP – 5 current clients
3. SSID: ABCVoice – VLAN 60 – Security: WPA2-Personal – 2 current clients
Two client STAs are connected to ABCData and can access a media server that requires authentication at the Application Layer and is used to stream multicast video streams to the clients.
What client stations possess the keys that are necessary to decrypt the multicast data packets carrying these videos?
In the basic 4-way handshake used in secure 802.11 networks, what is the purpose of the ANonce and SNonce? (Choose 2)
Given: ABC Company is implementing a secure 802.11 WLAN at their headquarters (HQ) building in New York and at each of the 10 small, remote branch offices around the United States. 802.1X/EAP is ABC’s preferred security solution, where possible. All access points (at the HQ building and all branch offices) connect to a single WLAN controller located at HQ. Each branch office has only a single AP and minimal IT resources.
What security best practices should be followed in this deployment scenario?
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:
What security controls would you suggest? (Choose the single best answer.)
A single AP is configured with three separate WLAN profiles, as follows:
1. SSID: ABCData – BSSID: 00:11:22:00:1F:C3 – VLAN 10 – Security: PEAPv0/EAP-MSCHAPv2 with AES-CCMP – 3 current clients
2. SSID: ABCVoice – BSSID: 00:11:22:00:1F:C4 – VLAN 60 – Security: WPA2-Personal with AES-CCMP – 2 current clients
3. SSID: Guest – BSSID: 00:11:22:00:1F:C5 – VLAN 90 – Security: Open with captive portal authentication – 3 current clients
Three STAs are connected to ABCData. Three STAs are connected to Guest. Two STAs are connected to ABCVoice.
How many unique GTKs and PTKs are currently in place in this scenario?
Given: The ABC Corporation currently utilizes an enterprise Public Key Infrastructure (PKI) to allow employees to securely access network resources with smart cards. The new wireless network will use WPA2-Enterprise as its primary authentication solution. You have been asked to recommend a Wi-Fi Alliance-tested EAP method.
What solutions will require the least change in how users are currently authenticated and still integrate with their existing PKI?
Given: Your organization is using EAP as an authentication framework with a specific type that meets the requirements of your corporate policies.
Which one of the following statements is true related to this implementation?
What field in the RSN information element (IE) will indicate whether PSK- or Enterprise-based WPA or WPA2 is in use?
Given: XYZ Hospital plans to improve the security and performance of their Voice over Wi-Fi implementation and will be upgrading to 802.11n phones with 802.1X/EAP authentication. XYZ would like to support fast secure roaming for the phones and will require the ability to troubleshoot reassociations that are delayed or dropped during inter-channel roaming.
What portable solution would be recommended for XYZ to troubleshoot roaming problems?
ABC Company has deployed a Single Channel Architecture (SCA) solution to help overcome some of the common problems with client roaming. In such a network, all APs are configured with the same channel and BSSID. PEAPv0/EAP-MSCHAPv2 is the only supported authentication mechanism.
As the Voice over Wi-Fi (STA-1) client moves throughout this network, what events are occurring?
Wireless Intrusion Prevention Systems (WIPS) provide what network security services? (Choose 2)
ABC Company requires the ability to identify and quickly locate rogue devices. ABC has chosen an overlay WIPS solution with sensors that use dipole antennas to perform this task. Use your knowledge of location tracking techniques to answer the question.
In what ways can this 802.11-based WIPS platform determine the location of rogue laptops or APs? (Choose 3)
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?
What attack cannot be detected by a Wireless Intrusion Prevention System (WIPS)?
Given: You have implemented strong authentication and encryption mechanisms for your enterprise 802.11 WLAN using 802.1X/EAP with AES-CCMP.
For users connecting within the headquarters office, what other security solution will provide continuous monitoring of both clients and APs with 802.11-specific tracking?
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?
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?
As a part of a large organization’s security policy, how should a wireless security professional address the problem of rogue access points?
