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?
Which of the following security attacks cannot be detected by a WIPS solution of any kind? (Choose 2)
Given: The Aircrack-ng WLAN software tool can capture and transmit modified 802.11 frames over the wireless network. It comes pre-installed on Kali Linux and some other Linux distributions.
What are three uses for such a tool? (Choose 3)
You are configuring seven APs to prevent common security attacks. The APs are to be installed in a small business and to reduce costs, the company decided to install all consumer-grade wireless routers. The wireless routers will connect to a switch, which connects directly to the Internet connection providing 50 Mbps of Internet bandwidth that will be shared among 53 wireless clients and 17 wired clients.
To ensure the wireless network is as secure as possible from common attacks, what security measure can you implement given only the hardware referenced?
What software and hardware tools are used together to hijack a wireless station from the authorized wireless network onto an unauthorized wireless network? (Choose 2)
What type of WLAN attack is prevented with the use of a per-MPDU TKIP sequence counter (TSC)?
Given: One of the security risks introduced by WPA2-Personal is an attack conducted by an authorized network user who knows the passphrase. In order to decrypt other users’ traffic, the attacker must obtain certain information from the 4-way handshake of the other users.
In addition to knowing the Pairwise Master Key (PMK) and the supplicant’s address (SA), what other three inputs must be collected with a protocol analyzer to recreate encryption keys? (Choose 3)
What 802.11 WLAN security problem is directly addressed by mutual authentication?
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?
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)
In what deployment scenarios would it be desirable to enable peer-to-peer traffic blocking?
As a part of a large organization’s security policy, how should a wireless security professional address the problem of rogue access points?
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?
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 disadvantage does EAP-TLS have when compared with PEAPv0 EAP/MSCHAPv2 as an 802.11 WLAN security solution?
When used as part of a WLAN authentication solution, what is the role of LDAP?
What preventative measures are performed by a WIPS against intrusions?
Wireless Intrusion Prevention Systems (WIPS) are used for what purposes? (Choose 3)
What field in the RSN information element (IE) will indicate whether PSK- or Enterprise-based WPA or WPA2 is in use?
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?
Wireless Intrusion Prevention Systems (WIPS) provide what network security services? (Choose 2)
Joe’s new laptop is experiencing difficulty connecting to ABC Company’s 802.11 WLAN using 802.1X/EAP PEAPv0. The company’s wireless network administrator assured Joe that his laptop was authorized in the WIPS management console for connectivity to ABC’s network before it was given to him. The WIPS termination policy includes alarms for rogue stations, roque APs, DoS attacks and unauthorized roaming.
What is a likely reason that Joe cannot connect to the network?
You work as the security administrator for your organization. In relation to the WLAN, you are viewing a dashboard that shows security threat, policy compliance and rogue threat charts. What type of system is in view?
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?
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?
