Why your computer needs a firewall enabled

[ Thanks to finid for this link. ]

"Central to this discussion is a fundamental understanding of the role a firewall plays in the overall security posture of a computer or computer system. In simple terms, a firewall protects a computer from network attacks. And there are host-based and network firewalls. A host-based firewall is the one running on and protecting a single device. That would be the one running on your personal computer, whether it be running a Linux, BSD or any other operating system.

"On the other hand, a network firewall is the one running on a device on the edge or perimeter of a network. That device could be a router, switch or VPN device. Your cable, DSL or Fiber Optics router falls in this category. The mistake that most people make is in thinking that if they have a firewall on the edge device, then none is needed on the personal computer sitting behind it. Very bad thinking."
