Which of the following mechanisms is the MOST secure way to implement a secure wireless
network?

A.
Filter media access control (MAC) addresses

B.
Use a Wi-Fi Protected Access (WPA2) protocol

C.
Use a Wired Equivalent Privacy (WEP) key

D.
Web-based authentication

Explanation:

WPA2 is currently one of the most secure authentication and encryption protocols for mainstream
wireless products. MAC address filtering by itself is not a good security mechanism since allowed
MAC addresses can be easily sniffed and then spoofed to get into the network. WEP is no longer
a secure encryption mechanism for wireless communications. The WEP key can be easily broken
within minutes using widely available software. And once the WEP key is obtained, all
communications of every other wireless client are exposed. Finally, a web-based authentication

mechanism can be used to prevent unauthorized user access to a network, but it will not solve the
wireless network’s main security issues, such as preventing network sniffing.
