There are many ways to secure wireless networks. Unfortunately, not all of them are very secure. In a series of articles, IT Hub’s Larry Loeb dissects the encryption schemes and other security features used with Wi-Fi (IEEE 802.11) networks, and provides tips on implementing them as part of your organization’s wireless network defenses.

WEP’s goal was to provide confidentiality, protect access to the network infrastructure by rejecting all non-WEP packets, and providing data integrity. There’s just one problem with Wired Equivalent Privacy: It isn’t.

WPA (Wi-Fi protected access) is an update of these security measures that fixes both the ciphers and the authentication methods used in the protocol. WPA increases Wi-Fi WEP security in two ways: it fixes the problem with an easily cracked key, and makes authentication of users possible.
