Software Firewalls: Made of Straw? Part 2 of 2
Israel G. Lugo, Don Parker

In part one of this article series we looked at how a personal firewall actually works and where it taps into the network stack to do its filtering. In part two we look at how easily the firewall's operation can be circumvented by inserting a malicious Trojan into the network stack itself.

Software Firewalls: Made of Straw? Part 2 of 2 2006-02-02

Blaming software firewalls for not stopping communicaiton between a compromised web server and an outside 'attacker' seems a bit off target. How does this server get exploited in the first place? To me, this seems to be where the problem lies. You put an exploitable web server on the net and then want to turn around and blame your packet filter for not letting you know its owned?? Since when is a software firewall an IDS?
