Overview
This chapter includes the following topics:
The Nortel SNA solution
Nortel Secure Network Access (Nortel SNA) solution is a protective framework to
completely secure the network from endpoint vulnerability. The Nortel SNA
solution addresses endpoint security and enforces policy compliance. Nortel SNA
delivers endpoint security by enabling only trusted, role-based access privileges
premised on the security level of the device, user identity, and session context.
Nortel SNA enforces policy compliance, such as for Sarbanes-Oxley and COBIT,
ensuring that the required anti-virus applications or software patches are installed
before users are granted network access.
