Hi, this is my first time, for asking something regarding Security.
We are a small Network with 20 Clients, windows XP-Pro SP2.
we do not have any Dedicated Firewall, like ISA or any thing else.
We have one Domain Controller only.
Now, we discover that one of my user he Install the Software called GFI LANGUARD for Scan the Whole Network.
here is my question, how can i know if some one is scan my PC for searching for any OPEN PORTS or Not.
is there any Software can i install, so it will help me to determine what exactly i have , or to give me an alert, i have some one is trying to scan my PC for any Open Ports.
Please Update me .
