Sniffer tool helps spot wireless LAN intruders

Network Associates' Sniffer Technologies division this week announced an update for its Sniffer Wireless analysis tool, adding a way to detect "rogue" devices that have joined a wireless LAN without permission.

Sniffer Wireless 2.0 does this detection automatically by comparing the list of IP and MAC addresses of authorized devices with the entire group of devices on the wireless LAN. The process enables Sniffer Wireless to spot any rogue device that may have joined the LAN without proper authorization. With the previous version, network managers had to do this detection manually, by looking through the report, according to Rich Van De Groenekan, a senior product manager at Sniffer Technologies.

In addition to automating this process, the company also added support for Agere's Orinoco wireless cards and Enterasys RoamAbout 802.11b wireless LAN cards. Previously, Sniffer Wireless supported Cisco and Symbol wireless LAN cards.

Sniffer Wireless 2.0 costs $7,995 for a two-year subscription or $9,995 for a perennial license.
