'''Nortel Secure Network Access''' (Nortel-SNA or NSNA) in [[Computer Networking| 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<ref>[http://www.lightreading.com/document.asp?doc_id=123813&page_number=1 NAC: More Is More]</ref> 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"<ref>[http://www.infoworld.com/article/04/04/29/HNdesantisint_1.html Eliminating threats on the network</ref>) 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 ([[Microsoft Systems Management Server|SMS]]), and/or an Active Portel.
The NSNA-4050 complies with the [[Trusted Computing Group]] (TCG) [[Trusted Network Connect]] (TNC) specifications<ref>[https://www.trustedcomputinggroup.org/groups/network/ Trusted Network Connect Work Group]</ref> 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.<ref>[http://www.nortel.com/solutions/securenet/collateral/esg_nac_whitepaper_8_aug_2007.pdf Addressing Enterprise Network Access Requirements]</ref>
