Title: Security through measurement for wireless LANs
Prof. David Kotz, Dartmouth College in Hanover NH
Date & Time: January 22, 2009 11:30
Venue: SIC 301, 03rd floor, ā€˜Cā€™ Block, Kanwal Rekhi Building

With the rise of Voice over wireless LAN (VoWLAN), any complete Wi-Fi security solution must address denial of service attacks, such as kicking off other clients, consuming excessive bandwidth, or spoofing access points, to the detriment of legitimate clients. Even authorized clients may be able to sufficiently disrupt service quality to make the network ineffective for legitimate clients. Our approach provides a new foundation for wireless network security, able to dynamically measure, analyze and protect a Wi-Fi network against existing and novel threats, including rogue clients and access points, with a focus on VoWLAN use cases. Our goal is to support thousands of APs and clients, quickly recognize most new attacks, and generate few false alarms.

In this talk I present an overview of work in progress, outlining the architecture of the MAP system and describing the results of our recent experiments with adaptive network measurement and initial methods of packet analysis.
