AirTight Receives U.S. Patent for Router AP Rogue Detection

Tuesday, June 30, 2009

Mountain View, CA -- AirTight® Networks, the global leader in wireless security and compliance solutions, today announced it has been granted US patent number 7,536,723 by the United States Patent and Trademark Office (USPTO) for router AP rogue detection techniques. Rogue APs can get connected to enterprise wired networks accidentally or by malicious actions without the knowledge of the network administrator. Intruders can access enterprise wired network from RF coverage of rogue APs bypassing traditional wired and wireless security controls. As a result, it is important for any wireless intrusion prevention system (WIPS) to continuously track APs visible in the enterprise airspace to determine if any of them is connected into the enterprise wired network and thus poses a security threat.

Among all the AP types, router APs (also called NAT APs) are by far the most common rogues, because they are the most common AP available to consumers. Moreover, router APs and particularly those which lack MAC adjacency between their wired and wireless interfaces, are undetectable by conventional MAC correlation techniques such as CAM table lookups. AirTight invented and pioneered active packet injection technology for comprehensive rogue detection in WIPS. The active packet injection technology provides highly accurate, comprehensive, instant and scalable AP network connectivity detection.

"Robust automatic AP classification and rogue detection via accurate on wire/off wire detection are among the factors which set AirTight's wireless intrusion prevention technology apart from the pack," said Dr. Hemant Chaskar, Director of Technology at AirTight Networks. "While other vendors are only now starting to implement router AP rogue detection capabilities, AirTight has been supporting it for years and now owns the patent on the technology which facilitates detection of router AP rogues."

About AirTight's Patent Portfolio

With the granting of this new patent, AirTight now has a total of 11 U.S. patents, one Australian patent, and one UK patent. It has more U.S. and international patents pending, many of which are undergoing active examination at patent offices of various countries and are expected to be granted this year.

AirTight's patent portfolio covers the entire range from broad wireless intrusion prevention architectures to specific algorithms and techniques.
