Dave methinks there is lots of hysteria in the arena

I have no firewall on my modem and no firewall on any of my machines. Yet the world is full of stories about exploits! Most of those are windows exploits!

Lets consider firewalls:

By RFC no router on the internet may route a private IP. So *every* router between you and bad guys is broken!
A firewall allows ESTABLISHED,RELATED traffic back, so if you've got a bad machine then bad guys can get to that machine and from there to your macs.
If you have a compromised machine then it is a target.

A decade ago one of the anti-virus companies offered $10 000 and a Sony Viao to first person to hack their honeypots. The windows honeypot was hacked in under an hour, the mac in a week (a flaw in safari) and the linux 'pot has never been hacked. They ascribed this to being unkewl to hack linux. Nonsense you'd be a hero for exposing a flaw (as has happened a couple of times.)

If you enjoy playing then by all means, if not then enjoy an icecream, except if you have windows machines on your network forget the icecream.

I guess IPV6 will change the landscape somewhat.
The subtle comment about ring 0: linux and mac work in a way that is very limited, what disk?, whereas widows you are not allowed, here is $100, well ok.

Query: heresay not allowed, who has ever had a mac hacked?
