What is a firewall?

A firewall gives you complete control over traffic to and from your computer. The firewall stops unauthorized access from intruders who want to access your computer. A good firewall also stops unauthorized traffic from your computer. Some programs, so called Trojan Horses, can give an intruder the possibility to run your computer from the inside. For this reason it is important to have complete control over the total flow of traffic your computer is involved in.

Why do I need a firewall?

An ordinary computer has sixty thousand ports through which it can access the Internet. It uses these to process the flow of information to and from the computer, Therefore it is very vulnerable to attacks.

If you are sitting at home surfing via your own ISP connection you have no corporate firewall behind which to shield yourself. If you are hooked up thru a broadband access you are even more vulnerable since you are connected thru the same IP-address for longer stretches of time.

It is therefore important to protect your computer against attacks. If you install a personal firewall you will definitely surprised by the sheer amount of intrusion attempts. Double check with your office to ensure that you are protected behind the safety of a firewall!!
