Tue, 15 Jan 2008 06:13 Brandon Teska Introduction There is a new version of this article here. Previously, we showed you how to secure your wireless with industrial strength RADIUS authentication via WPA-Enterprise. It turns out that there's a little back-story there. Wi-Fi Protected Access (WPA) was created to solve the gaping security flaws that plagued WEP. WPA solves this problem by rotating the key on a per-packet basis, which renders the above method useless. The Wi-Fi Alliance, creators of WPA, were aware of this vulnerability and took precautions accordingly.
First, this prevents the statistical key grabbing techniques that broke WEP by transmitting the key as a hash (cyphertext). So, like virtually all security modalities, the weakness comes down to the passphrase. Note: The techniques described in this article can be used on networks secured by WPA-PSK or WPA2-PSK.
