Adherence to Documented IT Security Policies, Standards, Procedures, and Guidelines

Compliance in the WAN Domain depends on implementing the best controls you can and on ensuring your WAN service provider’s controls are compliant as well. As with other domains, you should explore alternative controls for each security goal. You must ensure the correct controls are in place to balance each of the three C-I-A security properties.

As you analyze controls in the WAN Domain to meet compliance requirements, ensure each control satisfies your security policy. If a control does not support any part of your security policy, you should question its value to your organization. Different legislation, regulations, and vendor standards have different requirements. Implementing multiple types of controls decreases the likelihood that an attack will be successful and makes your WAN Domain more secure.
