Connecting to the Internet without a firewall is like leaving the keys in your car with the engine running and the doors unlocked while you run into the store. Although you may be able to get in and out before anyone notices, someone may take advantage of the opportunity. On the Internet, hackers use malicious code—such as viruses, worms, and Trojan horses—to try to find unprotected computers. A firewall can help protect your computer against these and other security attacks. It depends on the nature of the attack. While some attacks are just nuisances that may play simple pranks, others are created with malicious intent.

If you set up your firewall properly, hackers searching for vulnerable computers can't detect your computer. There are three basic types of firewalls available today. The first step in choosing a firewall is to determine which one is best for you. Your options include: Software firewalls, Hardware routers, Wireless routers. |
