How to detect intruders

[Sanal Kisi]

Hi,

As the admin, I need to find and detect intruders in my segment. I
need a tool that will just log the activity tries of the intruders
together with their IP and MAC addresses.

There are users trying to send trojans and viruses, and even managing
to get the control of other users PC's.

Any tool/method you can advise ?

Regards.

Look into setting up a "HoneyPot".
