SpectraGuard uses proprietary algorithms to analyze each device as it attempts to connect to the WLAN to determine whether it is safe or potentially malicious. Once that decision is made, administrators can use the tools built-in mapping feature to track devices on the WLAN, as well as those that are not connected to the network but are in range of it. "You have to be more accurate than an IDS [intrusion detection system] because you see wireless devices that have nothing to do with your network. You cant just start shutting them down," said David King, CEO of Wibhu, based in Mountain View, Calif. "But anything thats a real security threat, we block it instantly."In addition to the new releases from AirDefense and Wibhu, some other established vendors also are making moves in the WLAN security arena. Highwall Technologies Ltd. Dec. 1 will announce the latest release of its WLAN monitoring and security system, according to officials at the Sarasota, Fla., company. Highwall Enterprise 3.0 combines Wi-Fi sensors and antennas with a centralized management server. To read more about wireless security practices, read Carol Ellisons column. The software in the release has been redesigned to include enterprisewide snapshots of the threat levels that devices pose to the network at any given time across multiple buildings. Pricing depends on configuration, but Highwall Enterprise 3.0 starts at $9,995. It is available now. Highwall is in the final stages of being acquired by a large incumbent player in the WLAN space; the deal should close within the next three or four months, according to Rich Swier, Highwalls CEO.

SpectraGuard, which will be available later this month, can also be configured using a white-list feature, which restricts connection to clients explicitly permitted to use the WLAN. No pricing has been set, according to officials.
