Home PC Firewall Choices

Choices -- Your choices include using the firewall built into Windows, using a third party product, choosing an Internet security suite that includes a firewall, and/or using a hardware firewall router or gateway.
Microsoft Windows Firewall -- The Windows 7, Vista and XP Service Pack 2/3 operating systems have firewalls built in that are turned on by default to block threats from the Internet. You should leave this feature turned on until you replace it with third-party software and/or hardware.
Two-Way Third-Party Personal Firewall Software -- These firewalls block both incoming and outgoing threats. A computer may have outgoing threats when it becomes infected with a virus, Trojan horse or spyware. A challenge for this type of firewall is to distinguish between threats and legitimate software. Three common ways to address this are by vendors including a list of safe software for the firewall to check [white list], malware to block [black list] and/or by issuing a pop up alert to the user asking for advice on what to do [better for experts].

Hardware Firewalls -- A hardware firewall is usually a small box that sits between a modem and a computer or network. The firewall is either based on "network address translation" (NAT) which hides your computer from the Internet or NAT plus "stateful packet inspection" (SPI) for more protection. There are three basic types of hardware devices that include firewalls for home users, Wired Routers, Wireless Routers, and Broadband Gateways. They are inexpensive enough to be used with one computer and can also be used to create a home computer network. They can be used in addition to a software firewall on each computer because they run on a separate box preventing most compatibility problems.

Important Tips -- Never use two personal firewall software products at the same time. Fully uninstall one before installing another to prevent compatibility problems. Also, turn off the firewall built into Windows 7, Vista and XP Service Pack 2/3. After installation, be sure to test it with an online service like Security Space to make sure that it is configured correctly.
