X systems can be used to authenticate users, and then validate their system's compliance with a security standard before they are allowed to connect to the network. Enforcing security profiles can help reduce zero-day attacks, making NAC a useful solution. A firewall can't enforce system security policies, whereas an IDS can only monitor for attacks and alarm when they happen. Thus neither a firewall nor an IDS meets Kolin's needs. Finally, port security is a MAC address-based security feature that can only restrict which systems or devices can connect to a given port.
