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

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.
