A laptop with an 802.11b nic card and some software is one way of tracking down rogue wireless access points(assuming of course they are using 802.11b). It would also be really helpfull to have a current wiring diagram, so you can trace your laptops MAC through certain network segments, switches, etc.
The access points are most likely going to be left on all the time so you probably wouldn't need to setup any notification from the laptop. -Jimmy -----Original Message----- From: Boschmann, Armin [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 2:57 PM To: '[EMAIL PROTECTED]' Subject: Wireless LAN detection We have a policy of no-wireless at our sites. I want to audit this policy, similar to war-dialing, or more correctly war-driving. My thinking is to find illegal wireless equipment in realtime. My concern is insiders (temporary employees, contractors, 'bad' employees) plugging in a wireless access point, then accessing our network from the street, then disconnecting. So I am envisioning a computer with a wireless receiver that will look for TCP/IP traffic, and tell me if it detects communications to any of our computers. I can see several problems, such as distinguishing between our 192.168.x.x addresses and those on WLANs of our neighbors. Also I would have to harden the wireless detection computer, and ideally not connect it to our network at all yet have some means of notifying me (pager, cell modem). Does anyone know of a product that does this? Or if you think my approach is suspect, suggest another one? Armin Boschmann [EMAIL PROTECTED] Manitoba Hydro
