Cisco Security

CST 269

Course Description

Prerequisite: CST 161, 164, and 260. Introduces core security concepts and skills needed for the installation, troubleshooting, and monitoring of network devices to maintain the integrity, confidentiality, and availability of data and services. Stresses Command Line Interface (CLI) for securing Cisco equipment. Provides an in-depth, theoretical understanding of Cisco security in a logical sequence driven by technology. (15-30)

Outcomes and Objectives

  • Describe Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN).

Describe methods for implementing data confidentiality and integrity.

Objectives:

  • Describe how different types of encryption, hashes, and digital signatures work together to provide confidentiality, integrity, and non-repudiation.
  • Describe the mechanisms to ensure data integrity.
  • Describe the mechanisms used to ensure data confidentiality.

Implement secure virtual private networks.

Objectives:

  • Describe the purpose and operation of VPN types.
  • Describe the component and operations of IPSec VPNs.
  • Configure and verify a site-to-site IPSec VPN with pre-shared key authentication using SDM and CLI.
  • Configure and verify a remote access VPN.
  • Configure and verify SSL VPNs.

Given the security needs of an enterprise, create and implement a comprehensive security policy.

Objectives:

  • Describe the secure network lifecycle.
  • Describe the components of a self-defending network and business continuity plans.
  • Establish a comprehensive security policy to meet the security needs of a given enterprise.
