Secure Network Access SolutionNortel's Secure Network Access (SNA) is an award-winning Network Access Control (NAC) solution that controls and automates network access by enabling only trusted and privileged access based on a user's identity, context and the health of their device. It provides all the critical elements required to deliver a complete end-to-end NAC solution including: unified access policy, user authentication and device health assessment, authorization, continuous threat analysis and quarantine and remediation. Nortel SNA's flexible deployment options, Single-Sign-On installable client or clientless operation, suit both managed and unmanaged (e.g, guests, contractors) users. Secure Network Access supports Nortel and third-party Ethernet switches/WLAN Controllers, Windows, Mac and Linux Operating Systems, IP Phones, printers and other non-interactive devices. With enterprise-class performance, scalability and reliability, the Nortel Secure Network Access Switch can support up to 6,000 concurrent users and over 23,000 per four-unit cluster. In addition, Nortel SNA supports multiple enforcement mode options including 802.1X, SNMP, Nortel SSCP and DHCP and provides rich integration with Microsoft NAP. 
Why do I need it?
Since it ensures that only trusted users utilizing compliant devices can access network resources, Nortel SNA prevents the spread of viruses and worms, protects against data leakage and provides full network visibility. In addition, it automatically provisions role-based access, delivers quarantine and remediation and allows for centralized management throughout the entire enterprise. Key solution features include: Unified Access PolicyCentralized access policy and management for all users (e.g., employees, guests, remote workers) and devices (e.g., Windows, Mac and Linux PCs, printers and IP phones) across all network types including LAN, WLAN and VPN. Flexible support for Nortel and non-Nortel network infrastructures. Authentication and Device Health AssessmentUser/device authentication prior to authorizing access to network and services. Flexible device enforcement through 802.1X, SNMP, Nortel SSCP or DHCP. Optional or mandatory device health assessment to ensure endpoint compliance to policy. Flexible clientless and installable single sign-on client options. AuthorizationEnforces access control to specific network resources, services or applications based on user and device context (e.g., user identity, job function, device health and location). Ongoing Threat AnalysisContinuous host and network based threat analysis provided by the Nortel Health Agent based on Tunnel Guard technology and through integration with IDS/IPS and SIEM products. With continuous analysis of user and device health, security violations result in network termination or remediation. Quarantine and RemediationAutomated host quarantine and remediation based on authentication and/or security health assessment violation. User enforcement occurs at the network edge on the switch port or remote access device to ensure maximum security. Integration with Microsoft NAPRich integration with Microsoft Network Access Protection (NAP) on both the client and server levels to provide a robust security assessment utilizing the Nortel and Windows Health Agents, without requiring an upgrade to Windows Server 2008. 
How do I do it?
Nortel's Secure Network Access solution dramatically simplifies access complexity by centrally managing and enforcing access policy for all enterprise users across all network types. Nortel SNA protects customers' investments by supporting open industry standards (e.g., 802.1X, Trusted Network Connect), Microsoft Network Access Protection (NAP) and by supporting both Nortel and non-Nortel network environments. Nortel's SNA provides another critical element to the overall Nortel Layered Defense approach that fully compliments our secure switching, firewall, VPN and IDS/IPS solutions to offer an unprecedented level of security to our customers. 
What do I need?
The Nortel Secure Network Access solution consists of the following components: Policy Decision PointThe Nortel Secure Network Access Switch (SNAS) 4050 and 4070 provide the solution intelligence. Acting as a NAC appliance, they use authentication and health assessment information to make a policy decision and communicate with enforcement points to enforce the policy and control access to network resources. Policy Enforcement PointNortel and third-party Ethernet switches and WLAN controllers enforce network policies made by the Secure Network Access Switch. Health AgentThe Nortel Health Agent, based on Nortel Tunnel Guard technology, authenticates users and performs device health assessments by integrating with hundreds of security applications from over 70 leading vendors including Symantec, McAfee, Trend Micro, CA, ESET, Sunbelt, and SOPHOS EndpointsNortel SNA supports any device attempting network access including Windows, Linux and Mac PCs, IP phones, printers, gaming consoles and PDAs. In addition, with the Nortel Health Agent, the Secure Network Access solution provides remote access endpoint security through the Nortel VPN Gateway and VPN Router portfolios.
