If you have a Windows Domain and these machines are on that domain, you can
put a Group Policy in place that will disable the computers ability to
bridge connections, share connections, etc...  Doing regular sweeps with a
product like netstumbler throughout your facilities can also find your
problem machines.  These along with a known written company policy should
cover the company legally at least.

Policy against wireless, including cards.  Remove his wireless card.

One risk you have is his laptop latching on to hostile networks, once with
worms/viruses, as well as the threat you note.

Hi gang!

Here is a question for you...

We have a secure network with no wireless
connections whatsoever.

One of our laptop came in with credentials to log
on to the network through the Ethernet cable BUT
the person had just added a wireless card to his
laptop.

This situation actually came up and the person
could see external wireless networks (from other
companies around our building) and access
Internet through there. Yeah I know they're
stupid, but it's the real world!

This seems like a potential threat for taking our
data out the back door.
Copy files accessed through our network to
another network and voilà! No trace at all of the
mischief.

We monitor internet access and block non-company
Email (Yahoo, Hotmail etc.).

Suggestions?

Thanks and Happy Holidays!

Marty!
