A firewall is a system or group of systems that enforces an access control policy between several networks. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of devices which exists to block unwanted IP traffic and the other which exists to permit traffic.

Firewalls work by implementing various access control policies. It's also important to recognize that the firewall's configuration creates its policy based on the parameters you provide in your security control policy.

If you have a network in you SOHO business, you need firewall protection on the web side of your host and your networked computers. The Internet has hackers that seek to get into your network or server which makes life miserable for you and your system. The purpose of a firewall is to keep hackers out and to keep your system running proficiently and smoothly.

Even if you’re a small business, you should learn about the mechanics of how a firewall operates even if you have two computers on your network.
