CWNP Certified Wireless Security Professional (CWSP) 認定 CWSP-208 試験問題 (Q78-Q83):

質問 # 78
What is the purpose of the Pairwise Transient Key (PTK) in IEEE 802.11 Authentication and Key Management?

A. The PTK is XOR'd with the PSK on the Authentication Server to create the AAA key.
B. The PTK contains keys that are used to encrypt unicast data frames that traverse the wireless medium.
C. The PTK is a type of master key used as an input to the GMK, which is used for encrypting multicast data frames.
D. The PTK is used to encrypt the Pairwise Master Key (PMK) for distribution to the 802.1X Authenticator prior to the 4-Way Handshake.

正解：B

解説：
The Pairwise Transient Key (PTK) is derived during the 4-Way Handshake and is used to generate:
The EAPOL-Key Confirmation Key (KCK)
The EAPOL-Key Encryption Key (KEK)
The Temporal Key (TK), which encrypts unicast traffic
Incorrect:
A). The Group Master Key (GMK) is used to derive the GTK, not the PTK.
C). PTK is not XOR'd with the PSK-PTK is derived from PMK + other session parameters.
D). PMK is never encrypted or transmitted; it is pre-shared or derived and remains local.

質問 # 79
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 skill level of the wireless network security administrator(s).
B. Identify the manufacturer of the wireless infrastructure hardware.
C. Identify the manufacturer of the wireless intrusion prevention system.
D. Identify the wireless security solution(s) currently in use.
E. Identify the IP subnet information for each network segment.

正解：D

解説：
Before conducting a security audit of an 802.11ac WLAN, it is essential to know the current security implementations-such as the use of WPA2-Enterprise, 802.1X, or MAC filtering. This helps the auditor tailor tests to identify gaps, weaknesses, or misconfigurations in the existing system. Understanding the security solutions provides the most immediate insight into potential vulnerabilities.

質問 # 80
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?

A. All integrated 802.11ac adapters will work with most protocol analyzers for frame capture, including the Radio Tap Header.
B. The only method available to capture 802.11ac frames is to perform a remote capture with a compatible access point.
C. Laptops cannot be used to capture 802.11ac frames because they do not support MU-MIMO.
D. Integrated 802.11ac adapters are not typically compatible with protocol analyzers in Windows laptops.
It is often best to use a USB adapter or carefully select a laptop with an integrated adapter that will work.
E. Only Wireshark can be used to capture 802.11ac frames as no other protocol analyzer has implemented the proper frame decodes.

正解：D

解説：
Most integrated Wi-Fi adapters in Windows laptops are not capable of entering "monitor mode" or capturing
802.11ac frames properly. Compatibility with protocol analyzers like Wireshark or Omnipeek requires special drivers or specific USB adapters. Therefore, it is recommended to use a USB adapter known to support monitor mode and frame capture on 802.11ac for accurate and complete data capture.
Incorrect:
A). Not all adapters support protocol analyzer features.
C). MU-MIMO support is irrelevant for frame capture.
D). Other analyzers besides Wireshark can decode 802.11ac (e.g., Omnipeek).
E). Remote capture is not the only method-local USB adapters are effective too.

質問 # 81
What statement is true regarding the nonces (ANonce and SNonce) used in the IEEE 802.11 4 Way Handshake?

A. Both nonces are used by the Supplicant and Authenticator in the derivation of a single PTK.
B. The nonces are created by combining the MAC addresses of the Supplicant, Authenticator, and Authentication Server into a mixing algorithm.
C. The Supplicant uses the SNonce to derive its unique PTK and the Authenticator uses the ANonce to derive its unique PTK, but the nonces are not shared.
D. Nonces are sent in EAPoL frames to indicate to the receiver that the sending station has installed and validated the encryption keys.

正解：A

解説：
The PTK derivation requires:
PMK
ANonce (generated by the Authenticator)
SNonce (generated by the Supplicant)
MAC addresses of both Authenticator and Supplicant
Both the Supplicant and Authenticator derive the same PTK using identical inputs during the 4-Way Handshake.
Incorrect:
B). The nonces are shared-each party uses both ANonce and SNonce.
C). Nonces indicate no such validation message.
D). The MACs are part of the PTK input but not used to generate the nonces themselves.

質問 # 82
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?

A. WLAN devices that are discovered must be classified (rogue, authorized, neighbor, etc.) and a WLAN policy must define how to classify new devices.
B. Upstream and downstream throughput thresholds must be specified to ensure that service-level agreements are being met.
C. Authorized PEAP usernames must be added to the WIPS server's user database.
D. Separate security profiles must be defined for network operation in different regulatory domains

正解：A

解説：
After deploying a WIPS, an essential baseline activity is to classify all detected devices in the RF environment. These classifications allow the system to enforce security policies and detect policy violations.
Classifications include:
Authorized (managed devices)
Rogue (unauthorized, possibly dangerous)
Neighbor (not part of your network but legitimate)
External or Ad hoc devices
Without this initial classification, WIPS cannot properly assess threats or trigger alarms.
