Cisco Network Admission Control Last modified: Monday, November 13, 2006
Abbreviated as NAC, Cisco's Network Admission Control is a set of technologies and solutions that use the network infrastructure to enforce security policy compliance on all devices seeking to access network computing resources in order to limit damage from emerging security threats. NAC is designed to allow network access only to compliant and trusted endpoint devices (PCs, servers and PDAs, for example) and can restrict the access of noncompliant devices. NAC assesses all endpoints across all access methods, including LAN, wireless connectivity, remote access and WAN. [Source: Cisco Systems] In October 2006, Cisco and Microsoft formally announced interoperability between the Cisco Network Admission Control (NAC) and Microsoft Network Access Protection (NAP) solutions. Interoperability will be supported with the release of NAP in the future version of Windows Server which is scheduled to be available in the second half of 2007. The interoperability architecture allows customers to deploy both NAC and NAP incrementally or concurrently. See also Microsoft Network Access Protection (NAP). Also see Webopedia's "Did You Know... All About Network Access Controls".
Cisco Network Admission Control and Microsoft Network Access Protection Interoperability Architecture (PDF) Cisco Systems and Microsoft Corp. have developed an interoperability architecture that allows customers to deploy both the Network Admission Control (NAC) platform available from Cisco and the Network Access Protection (NAP) platform being developed by Microsoft.

EnterpriseNetworkingPlanet: NAC: Buzzword Compliance Can Mean Blind Alleys From a security perspective, there are many things wrong with this concept. The primary concern is that of trusting an endpoint to report its own health. But the reasons that so-called network admission control (NAC) has not caught-on is it requires a massive investment in infrastructure to counter a problem that has already been addressed by patch and configuration management. Immunize Networks with Policy Enforcement NAC Appliance technology, based on the Cisco Clean Access product line, provides rapid deployment with self-contained endpoint assessment, policy management, and remediation services. Introduction to Network Access Protection Network Access Protection (NAP) is a new platform to perform computer health policy validation, ensure ongoing compliance with health policies, and optionally restrict the access of computers that do not comply with system health requirements. Network Access Protection provides an infrastructure and an API set for extending Network Access Protection functionality.
