Firewalls

Installing a firewall on any computer with a broadband connection is almost mandatory. A permanent, ‘always-on’ broadband connection means that your computer has a fixed identity on the Internet, which could be exploited by rogue software programs or viruses.

A firewall basically sits between your computer and the Internet and acts as a buffer, or safety zone, to protect your computer from any malicious activity. Firewalls can either be software programs or separate pieces of computer hardware. Most home users with a single computer will find that a software firewall is normally sufficient to meet their needs.

Without effective firewall protection, it is almost inevitable that your computer will become compromised at some point. A firewall is therefore a critical element of your home computing set-up. Although installing a firewall may be a steep learning curve, it is necessary to understand the importance of having firewall protection if you have a permanent, 'always-on' broadband Internet connection.
