IBM last week announced an improved version of its wireless security monitoring tool, adding self-sensor and self-diagnosis capabilities. Known as Distributed Wireless Security Auditor, the software runs on Linux-based desktops and laptops and as a thin client on personal digital assistants and other wireless devices.
The software can locate rogue and misconfigured WLAN (wireless LAN) access points and report the results to the central server. The software is essentially a wireless packet sniffer and is able to determine the location of access points based on their signal strength.
The DWSA system needs at least three of the wireless clients to pick out each access point to triangulate on its position, IBM said.
