Nortel Secure Network Access

Nortel Secure Network Access (Nortel-SNA or NSNA) in computer network is a Network Access Control system designed by Nortel to guarantee endpoint security policy compliance and remediation (also known as comply to connect [ [http://www.lightreading.com/document.asp?doc_id=123813&page_number=1 NAC: More Is More] ] or, "comply to my policies and then you can connect. And if you can't comply, come into this safe zone where I'll remediate, I'll get you back to a trusted state" [ [http://www.infoworld.com/article/04/04/29/HNdesantisint_1.html Eliminating threats on the network] ] ) at the network endpoint. The overall objective is to make policy based decisions about who gets access to a network segment and what they can do once they are admitted. The health checking policy provides additional security protection by limiting or restricting access to endpoints identified to be “unhealthy” based upon a enterprise policy definition.

The Nortel Secure Network Access Switch (SNAS) 4050 is a device that centrally controls access policies and admission controls for integration with wired, wireless and mobile users and devices. The SNAS-4050 switch is the policy integration point between Nortel and/or 3rd party switches/routers/VPN systems and the Policy authentication (AD server/certificate server/802.1x), remediation (SMS), and/or an Active Portel.

The NSNA-4050 complies with the Trusted Computing Group (TCG) Trusted Network Connect (TNC) specifications [ [https://www.trustedcomputinggroup.org/groups/network/ Trusted Network Connect Work Group] ] so a customers will not be locked into a proprietary architecture. The Trusted Network Connect (TNC) specification is not part of a single antivirus software, personal firewall, or security application. The TNC specification as well as the NSNAS-4050 supports third party and legacy Nortel switches to provide the best return on investment protection and is closely integrated with Microsoft's Network Access Protection (NAP) technologies in the Vista desktops and Windows Servers.
