CompTIA Security Plus Mock Test Q157

Which of the following means of wireless authentication is easily vulnerable to spoofing?

A. MAC Filtering
B. WPA – LEAP
C. WPA – PEAP
D. Enabled SSID

Correct Answer: A
Section: Network Security

Explanation:
Each network interface on your computer or any other networked device has a unique MAC address. These MAC addresses are assigned in the factory, but you can easily change, or “spoof,” MAC addresses in software.
Networks can use MAC address filtering, only allowing devices with specific MAC addresses to connect to a network. This isn’t a great security tool because people can spoof their MAC addresses.

Incorrect Answers:
B: WPA – LEAP (Wifi Protected Access – Lightweight Extensible Authentication Protocol) combine to ensure a secure wireless authentication method. WPA – LEAP is not easily
vulnerable to spoofing.
C: WPA – PEAP (Wifi Protected Access – Protected Extensible Authentication Protocol) combine to ensure a secure wireless authentication method. WPA – PEAP is not easily
vulnerable to spoofing.
D: Enabling SSID broadcasting makes the wireless network visible to clients. It is not a means of wireless authentication.
