Firewalls

Firewalls provide system protection by filtering ports and network traffic. Many modern firewalls also contain intrusion detection facilities or even intrusion prevention options, allowing defenses to be constructed automatically.

These are beautiful, but complex systems, which are not necessarily easy to administer. A mistake is easily made, leaving the door wide open to intruders.
