The Snort-Wireless project is an attempt to make a scalable (and free!) 802.11 intrusion detection system that is easily integratable into an IDS infrastructure. It is completely backwards compatible with Snort 2.0.x and adds several additional features. Currently it allows for 802.11 specific detection rules through the new "wifi" rule protocol, as well as rogue AP, AdHoc network, and Netstumbler detection.
