    In the previous article in this series, we covered hardware firewall-routers. Firewalls are an important part of a privacy protection strategy because they prevent intruders from gaining access to valuable information that is stored on a computer.

The best PC firewalls track incoming and outgoing traffic, and allow users to set up rules governing what programs on the computer will be allowed to establish connections to the Internet. Best of all, many PC firewalls are free, although even if they are available commercially, prices tend to be reasonable.
