 Whether you are a home user or a business, a well configured firewall is an integral component of your network's security.
Firewalls function as a buffer zone between your computer (or local network) and the Internet. When properly configured, a firewall can prevent hackers from remotely accessing your computer as well as protecting your network from common attacks such as Denial of Service (DoS).
There are two types of firewalls: hardware and software.
Most routers include a hardware firewall which protects your Local Area Network (LAN) from broad range external attacks and can be configured to forward external ports to the LAN for Remote Desktop and server hosting.
Software firewalls such as those that come with Norton and McAfee's Internet Security suites, ZoneAlarm, and the Windows XP and Vista integrated firewalls, can be used in conjunction with a hardware firewall as added security for individual computers.
A software firewall can be configured to allow only certain programs to access the Internet, preventing, for instance, a spyware application from "phoning home" with your personal data. If left unconfigured a software firewall can also be a nuisance, constantly asking users to allow or disallow Internet access for applications.
