I already covered firewalls during part 3 of my computer security series, but now that we are focusing on desktop security we once again have to review the subject. For part 3 the firewall topic was in regards to the perimeter, or network; which is usually a hardware based device. In part 7 the topic is desktop or personal firewalls.
I won't bore everyone by going into detail on firewalls again, but if you have not done so already, please read the original topic Computer Security 101 - Part 3 - Firewalls. Instead, I will be covering the importance of having a separate personal firewall on each and every desktop computer.
To most people, including many industry professionals, a personal firewall is considered overly redundant. There is a hardware based firewall keeping your network secure already, why would someone want a firewall running on their local computer? It is also an extra application running on the computer, taking up resources and slowing everything down. So why have one?
