Hi,
If you can get mac addresses from CAM table on the client switches (snmp
query), then you
can create database of accepted MAC's and get email/page/whatever alert
about any new MAC address in the environment.
Think about scenario where someone first plug the small switch and then
access point
to that switch.
Something which collects all these MAC's (arpwatch) or internal database +
alerting
could help your client. MAC addresses are based on vendor, and you can
download
that list and get alerted only on wireless vendors, if they don't care
about "unknown"
PC's plugged into their network.

Detecting Rogues from the wired
side
Hi list,
The client has got a huge network to be audited for Rogue Access
Points...the timeframes are tight so we're going to work on the wired side,
only, and I've been wondering how to do this more effectively.I have
identified two options:
- Run a 'customized' version of nmap to include only the Wireless AP
signatures in the fingerprint database and investigate on any devices that
are different makes & models from the ones 'officially endorsed'
- Acquire a copy of RAPIDS from Airwave.com... which is supposed to do just
that, and has a large databaase of Wireless Vendor Fingerprints. Has anyone
used it or do you have any alternative products to suggest?
I'm looking forward to your thoughts, folks.
Many thanks, once again
Stelios
