Security of Wireless LANs is a hot item. The ongoing stories about wardriving, WEP - key cracking and man-in-the-middle attacks have given a lot of system operators cold feet. The pilot shows that as long as a strong EAP capable protocol is used 802.1X provides a framework that gives a sufficient level of security for the intended purpose, i.e. access control to the network. For data integrity or privacy issues a number of wireless security extensions (WPA, TKIP, 802.11i etc.) have been proposed, that also build on the 802.1X framework.
