there's just no denying it. A few years ago you could happily go about your business on the web without any form of protection, and still face only a slim chance of being virus infested, hacked or otherwise interfered with. These days it's practically impossible. There are vast amounts of viruses and malware infections moving through the Internet daily, many of which need no prompting or permission to infect an unprotected computer.
To prepare yourself for today's Internet environment, you need the holy trinity of computer security: effective antivirus/anti-spyware software, regular updates and a firewall. We'll be looking at the latter today, in detail.
In this guide, we will walk you through every procedure involved in setting up and configuring a hardware or software firewall to protect your computer or network. We will also cover how to circumvent the problems firewalls can often cause to applications, and tackle the issue of hosting a game, web or FTP site on a firewall protected system. In short, this should be the last firewall article you'll need to read. As for the first article you should read, our original guide to firewalls and Internet security contains more information on how firewalls work and the kind of threats you face on the web.
