Putting your faith in firewalls

I ran across a great article (via Tomalak's Realm) by Simson Garfinkel about how firewalls promote the illusion of security while simultaneously 1) still allowing mischief and 2) blocking legitimate uses. He doesn't advocate getting rid of them, but points out that internal users and internal desktops are how most viruses and information loss occurs. The article has a good non-technical explanation of what firewalls are.

Since I'm on record as hating firewalls because of reason 2), it's good to see other people pointing out the limitations of firewalls.
