A firewall is hardware or software that controls access to and from your network.

The advent of always on networks such as ADSL, Cable and Lease lines has given the more malicious computer user an abundance of opportunity to target your network. A firewall protects your computer systems by controlling access to your network by blocking unwanted traffic. A brief summary of features is listed below:

• Blocks traffic to and from your network based on rules that block specific ports configured by the firewall administrator.
• Blocks traffic to your network based on rules predefined in the firewall software(SPI).
• As well as keeping unauthorised users out of your network a firewall can often prove useful in controlling what your users can bring into your network - for example you may want to stop certain users viewing websites of a non work related nature or cyber skiving using chat type programs.
