Network Access Protection is a platform for Microsoft Windows Server Longhorn (now in beta testing) and Windows Vista that provides policy enforcement components to help ensure that computers connecting to a network meet administrator-defined requirements for system health. Internet Protocol security (IPsec) is a set of Internet Engineering Task Force (IETF) standards that provides cryptographic protection for IP-based traffic. This document provides an overview of the Network Access Protection platform and IPsec, and how IPsec Enforcement in the Network Access Protection platform works to provide system health policy enforcement for IPsec-protected communication.
