Cisco DESGN 2.1: Defining Network Security

Overview/Description
Network security is an essential network service that spans the entire network. The scope of a network security solution is determined by organizational requirements and potential threats that are evaluated for each network component.

The course then discusses network components as potential targets and explains how risk assessment is used in a security policy.
