Free registration required

Executive Summary

The Nortel Layered Defense approach to network security is designed to ensure there are no single points of security failure in a network, thus allowing the network to adapt to new and changing threats. It is accomplished by using multiple approaches to security enforcement at multiple areas within a network. Based on open, standards-based solutions, this approach enables easy integration and simplified operations that reduce the overall network security total cost of ownership.
