Triangulation homes in on rogue WLan access points

    Although wireless access points use encryption to secure network traffic, access to the WLan is open to anyone with a valid log-in. Foundry Networks aims to control this access based on the physical location of the end-user. The technology uses triangulation between three access points to determine the location of a WLan user to within five metres, said the company.

    The technique can be used by IT managers to locate and eliminate rogue access points – a common security problem encountered on company networks due to the ease with which access points can be set up.

    Wireless access is a growing threat to corporate security, because of the increased availability and use of wireless devices, said Forrester Research.
