Security Engineering: Securing Networks

This course explores network security by analyzing network device deployment, reviewing network infrastructure security controls, and implementing network security monitoring. By the end of this material, you should be able to assess network infrastructure and determine where to place network security controls in order to provide the best protection for an organization's network infrastructure. Familiarity with fundamental security principles and basic networking concepts is assumed.

This module analyzes the security controls that should be applied to the core categories of network devices — switches, routers, wireless access points, VPN concentrators — along with the logging practices and physical monitoring techniques (network taps) that support their secure deployment.

Depending on the sensitivity of the environment, a security engineer can choose the more forgiving protect/restrict modes, or immediately shut the port down as soon as an unknown device connects.
