I am having network at my workplace and it is configured using 2 wire router. All the computers are having Sygate personal firewall developed by Sygate technologies. Nowadays I have observed that all of my computers are getting port scan attack. My Sygate firewall is detecting port scan attack and it is blocking that attack. Many times port scan attack is detected by a specific IP address. So I want to know what I shall do as I am getting these attacks and what all precautions should be done against it.
