On the same token, it is not safe to completely rely on firewalls to provide
protection for your site. (They are but one aspect.) While they may make
remote network intrusion more difficult, the problem is not insurmountable.

awareness must be maintained. Otherwise, only one security mechanism needs
to be defeated after which the entire network opens wide up.
