Network Admission Control

NAC enables you to control the degree of access permitted from computers
accessing your network through a AAA client configured to enforce NAC. The
basis of NAC is the validation of the posture, or state, of computers on a network.
The role of Cisco Secure Access Control Server (ACS) for Windows Server in
NAC is to perform posture validation.
