Hello Armin, Take a look at 'Observer' by Network Instruments (www.networkinstruments.com) It is a realtime packet sniffer that will work with any NDIS5 supported NIC including 802.11a and 802.11b and it has the ability to send alerts from something as simple as a local popup to Dialing a pager or sending an e-mail via a dial-on-demand TCP/IP connection.
-----Original Message----- From: Boschmann, Armin [mailto:[EMAIL PROTECTED]] Sent: Friday, December 06, 2002 11:45 AM 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?
