WLANs vulnerable to hacking

Tuesday, 15 June 2004, 8:54 AM EST

Wireless local area networks are susceptible to hackers who compromise them through unprotected access points or from peer workstations, Gartner says. The research firm says the solution -- fixed wireless intrusion-detection sensors -- is more expensive but better than the method of walking the perimeter of a WLAN with handheld detection devices.

The fundamental security risk with a WLAN is that intruders entering the network can pose as trusted participants. "Once they are associated with the network, they will be difficult to detect because they may not be visible in or near the network site," said Gartner analyst John Pescatore. "A clever hacker will play it safe and use the company's resources quietly -- and, as a result, may never be found."
