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.
A. 2, 3, 4, 1
B. 1, 2, 3, 4
C. 4, 3, 1, 2
D. 3, 4, 1, 2
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?
A. Probe request
B. Beacon
C. RTS
D. CTS
E. Data frames
What attack cannot be detected by a Wireless Intrusion Prevention System (WIPS)?
A. MAC Spoofing
B. Eavesdropping
C. Hot-spotter
D. Soft AP
E. Deauthentication flood
F. EAP flood
What security vulnerabilities may result from a lack of staging, change management, and installation procedures for WLAN infrastructure equipment? (Choose 2)
A. The WLAN system may be open to RF Denial-of-Service attacks
B. WIPS may not classify authorized, rogue, and neighbor APs accurately
C. Authentication cracking of 64-bit Hex WPA-Personal PSK
D. Management interface exploits due to the use of default usernames and passwords for AP management
E. AES-CCMP encryption keys may be decrypted
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?
A. Joe disabled his laptop's integrated 802.11 radio and is using a personal PC card radio with a different chipset, drivers, and client utilities.
B. Joe's integrated 802.11 radio is sending multiple Probe Request frames on each channel.
C. An ASLEAP attack has been detected on APs to which Joe's laptop was trying to associate. The WIPS responded by disabling the APs.
D. Joe configured his 802.11 radio card to transmit at 100 mW to increase his SNR. The WIPS is detecting this much output power as a DoS attack.
Given: A network security auditor is preparing to perform a comprehensive assessment of an 802.11ac network's security.
What task should be performed at the beginning of the audit to maximize the auditor's ability to expose network vulnerabilities?
A. Identify the IP subnet information for each network segment.
B. Identify the manufacturer of the wireless intrusion prevention system.
C. Identify the skill level of the wireless network security administrator(s).
D. Identify the manufacturer of the wireless infrastructure hardware.
E. Identify the wireless security solution(s) currently in use.
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?
A. All WIPS sensors must be installed as dual-purpose (AP/sensor) devices.
B. A location chipset (GPS) must be installed with it.
C. At least six antennas must be installed in each sensor.
D. The RF environment must be sampled during an RF calibration process.
Wireless Intrusion Prevention Systems (WIPS) are used for what purposes? (Choose 3)
A. Performance monitoring and troubleshooting
B. Enforcing wireless network security policy
C. Detecting and defending against eavesdropping attacks
D. Security monitoring and notification
E. Preventing physical carrier sense attacks
F. Classifying wired client devices
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?
A. WIPS sensor software installed on a laptop computer
B. Spectrum analyzer software installed on a laptop computer
C. An autonomous AP mounted on a mobile cart and configured to operate in monitor mode
D. Laptop-based protocol analyzer with multiple 802.11n adapters
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?
A. WEP
B. RC4
C. CCMP
D. WPA2
