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.

Assessment Methods

Examine

• Security planning policy
• procedures addressing information security architecture development
• procedures addressing information security architecture reviews and updates
• enterprise architecture documentation
• information security architecture documentation
• system security plan
• security CONOPS for the system
• records of information security architecture reviews and updates
• other relevant documents or records

Interview

• Personnel with security planning and plan implementation responsibilities
• personnel with information security responsibilities
• personnel with information security architecture development responsibilities

Test

• Mechanisms supporting and/or implementing the development, review, and update of the information security architecture
• processes for developing, reviewing, and updating the information security architecture
