Firewalls create false sense of Security
Preoccupation with firewalls can divert attention and resources
away from important issues of locking systems down.
Computer security researcher at the San Diego Supercomputing Center
(SDSC), Abe Singer said companies can spend 90 percent of their
security efforts on firewalls and not much of anything else. "I'm not
saying firewalls are completely irrelevant, but how much effort do you
spend on security?" Singer asked. "Do security at the host, not just
the perimeter. You should be worried about what users are doing,
because if an attacker is going through the perimeter [without secure
hosts] then it's game over."
