ICF is a Windows XP feature that protects Internet-connected computers from unauthorized access .

The full-form of ICF is ” Internet Connection Firewall .” When ICF is enabled in a computer , then Windows keeps a log of all incoming requests that come from other systems on the Internet.

If a request is something that has been requested by the user, such as a web page, then the transmission will not be affected in any way. But if the request is a bit unsolicited or unauthorized or which cannot be recognized by the system, then the transmission is dropped.

This is because it prevents any kind of hacker intrusion or intrusion of malicious software such as Spyware from doing some damage to the computer.

Where ICF limits incoming traffic from the Internet, it does not affect outgoing traffic. This means that whatever data is sent by your computer is still vulnerable to viruses or other disruptions, where ICF is still enabled.

If you have multiple computers that share the same Internet connection via ICS , you can enable ICF for all computers. At the same time, you can enable ICF for the router or system which is directly connected to the internet, not for each individual system.
