What is a Firewall
A firewall is a security system that acts as a protective boundary between a network and the outside world. Windows XP includes Internet Connection Firewall (ICF) software you can use to restrict what information is communicated between the Internet and your home or small office network. ICF also protects a single computer connected to the Internet with a cable modem, a DSL modem, or a dial–up modem.
