Security without Firewalls | 05 Jun 2006 –

A thought provoking article and presentation (pdf) about the role of firewalls in a secure network. Although I disagree with the conclusion of Abe Singer, computer security manager for the SDSC’s Security Technologies Group, I concur with his assesment and arguments.

“Firewalls can’t protect you from what users are doing inside the company,” Singer said. “If I want to steal from a bank, I won’t try to punch through their firewall. I’ll get a job in the mailroom.”…

There is a pervasive myth that firewalls are necessary for effective security. Firewalls have become a panacea, and are assumed to magically protect everything. The net result is often that a network is less secure.
