A layered defense uses multiple approaches to security enforcement at multiple areas within a network. This approach removes single points of security failure in order to secure enterprise information assets. A common example to security enforcement would consist of the following:

  • Endpoint security to ensure valid identity and security policy compliance of the connected device

  • Secure communications to ensure that information is protected from unauthorized discovery over the network

  • Perimeter security to keep the "bad stuff" out by securing the boundaries between zones of different levels of trust

  • Core network security to keep an eye on any malicious software and traffic anomalies by enforcing network policy and enabling survivability
