RE: Scan for "outsider" Pcs on network

["Robert D. Holtz - Lists" <robert.d.holtz () gmail com>]

If security is paramount then you would want to setup your switching fabric
to perform MAC based restrictions by port.  This is one of the best ways of
making sure you know what's hooked up.  Anyone just trying to hook up to a
port will get nowhere.

Of course, this doesn't prevent someone from going up to a machine that's
already allowed on the 'net and doing what ever they please.

I come across a program call air-snare that is able to detect that.  But you
will need to have a list of all your systems mac address.  It is like an IDS
program.  I believe that most of the IDS program is able to do that.

Is there a way to setup a scan and be notified of an intruding pc that is
physically plugged into the network? When you have an enviroment with a
large amount of network jacks, it's hard to make sure the ones no longer in
use are turned off, and that no "visitors" have sat down to use your network
connections, esp. if you have a large amount of contractors in and out. It
got me to searching the net, and so far I have found one cemmercial product
that can do it, but nothing else. Any suggestions?
