Network Access Protection, a proposed platform for Microsoft Windows Server "Longhorn," the next version of the Windows Server operating system, provides policy enforcement components that help ensure that computers connecting to a network meet administrator-defined requirements for system health. Administrators can use a combination of policy validation and network isolation components to control network access.
Administrators can also choose to temporarily isolate computers that do not meet requirements to a more secure network segment, called a quarantine network. D
epending on the configuration chosen, the quarantine network might contain resources required to update the computers so that they then meet the requirements for full network access. Network Access Protection includes an application programming interface (API) set for developers and administrators to create complete solutions for network access, isolation, and policy compliance.
