Cracking the wireless security code
So we assembled 23 wireless products from 17 vendors and ran them through a battery of tests aimed at getting the answer.
Wired Equivalent Privacy (WEP) is very weak in many products, and we don't recommend using it other than in very specialized cases. WEP's successor, Wi-Fi Protected Access (WPA) has flaws but provides solid security when combined with 802.1X authentication and deployed carefully. Ultimately, 802.11i, the standard that replaces WEP and WPA, will provide all the tools needed to protect WLANs.
