When you create a home network connected to the Internet, you increase the vulnerability of your computers to unauthorized access, including viruses. To protect your network, you need to create a type of barrier called a firewall. Windows XP comes with a firewall that you create when setting up a home network.
How does a firewall work?
Like an actual firewall built to prevent fire from spreading between adjoining buildings, computer firewalls prevent the spread of unauthorized communication between an individual computer or group of networked computers and the Internet. One of the most effective ways to protect a home network—and the least expensive—is to create a firewall on the ICS host computer, and to make sure that computer is the only one on the network with a direct connection to the Internet.
