Assessment Objective

Determine if:

• CA-09a. internal connections of [Assignment: system components] to the system are authorized;
• CA-09b.
  • CA-09b.[01] for each internal connection, the interface characteristics are documented;
  • CA-09b.[02] for each internal connection, the security requirements are documented;
  • CA-09b.[03] for each internal connection, the privacy requirements are documented;
  • CA-09b.[04] for each internal connection, the nature of the information communicated is documented;
• CA-09c. internal system connections are terminated after [Assignment: conditions];
• CA-09d. the continued need for each internal connection is reviewed [Assignment: frequency].

Assessment Methods

Examine

• Assessment, authorization, and monitoring policy
• access control policy
• procedures addressing system connections
• system and communications protection policy
• system design documentation
• system configuration settings and associated documentation
• list of components or classes of components authorized as internal system connections
• assessment report
• system audit records
• system security plan
• privacy plan
• other relevant documents or records

Interview

• Organizational personnel with responsibilities for developing, implementing, or authorizing internal system connections
• organizational personnel with information security and privacy responsibilities

Test

• Mechanisms supporting internal system connections
