Assessment Objective

Determine if:

• a security architecture for the system that describes the requirements and approach to be taken for protecting the confidentiality, integrity, and availability of CUI is developed.
• a security architecture for the system that describes how the security architecture is integrated into and supports the enterprise architecture is developed.
• a security architecture for the system that describes any assumptions about and dependencies on external systems and services is developed.
• the security architecture is reviewed and updated [Assignment: frequency] to reflect changes in the enterprise architecture.
• planned security architecture changes are reflected in system security plans, concept of operations, criticality analyses, organizational procedures, procurements, and acquisitions.
