CompTIA Security+ Question E-41

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

Answer: A

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.
