Why do I need a firewall?

Any computer that is online can be hacked at any time, but dialup (phone line) connections are really pretty safe. There are certain settings called IP Addresses that change every single time you dial up and log on, making it very unlikely for you to be a target. Therefore, I would say that if you have a dialup line, just turning on your free Windows XP Firewall is probably enough protection.

A solid firewall will help you stop intruders from accessing your system. You keep your internet link to the outside world but the outside world can't view you unless you want them to. With a firewall in place you will still have typical email access, but chat and other interactive programs will require you to take an extra step to grant access before you can use them. A firewall is powerful but unobtrusive, just like a deadbolt lock inside a door.
