Stands for “Internet Connection Firewall.” ICF is a Windows XP function that protects computer systems linked to the Internet from unauthorized entry. When ICF is enabled, Windows retains a log of incoming requests from different programs on the Internet. If the request is one thing the person has requested, like a Web web page, the transmission won’t be affected. However, if the request is unsolicited and isn’t acknowledged by the system, the transmission can be dropped. This helps stop intrusion by hackers or malicious software program akin to spyware and adware.

While ICF limits incoming site visitors from the Internet, it doesn’t have an effect on outgoing site visitors. This means knowledge despatched out of your pc continues to be weak to viruses or different disruptions even when ICF is enabled. If you could have a number of computer systems sharing the identical Internet connection through ICS, you’ll be able to allow ICF for all of the computer systems. However, it’s best to allow ICF for the router or system linked on to the Internet connection, not for every particular person system.
