I just read this article this morning...The most interesting part I
though was they assumed they were safe because they had a firewall, but
it came in through a non-firewalled entrance. They had an T1 going from
an outside contrator's site to a point on their network that was behind
their firewall. The lesson to be learned here is, just because you trust
someone else, doesn't mean you can trust their network. :)
