Network Access Protection (NAP) is a new platform and solution that controls access to network resources based on a client computer’s identity and compliance with corporate governance policy. NAP allows third-party software vendors and system integrators to create complete solutions for validating and enforcing system health requirements for network access or communication.
This white paper describes the architecture of the NAP platform and the details of how NAP works for enforcement methods that are provided with Windows Server 2008, Windows Vista, and Windows XP Service Pack 3.
Note The NAP platform is not the same as Network Access Quarantine Control, which is a capability provided with Windows Server 2003 to provide additional protection for remote access (dial-up and VPN) connections. For more information, see Network Access Quarantine Control in Windows Server 2003.
