CA — SECURITY ASSESSMENT AND AUTHORIZATION
CA-9: INTERNAL SYSTEM CONNECTIONS
NIST 800-53R4 Membership CA-9:
- a. Authorizes internal connections of [Assignment: organization-defined information system components or classes of components] to the information system; and/li>
- b. Documents, for each internal connection, the interface characteristics, security requirements, and the nature of the information communicated.
This control applies to connections between organizational information systems and (separate) constituent system components (i.e., intra-system connections) including, for example, system connections with mobile devices, notebook/desktop computers, printers, copiers, facsimile machines, scanners, sensors, and servers. Instead of authorizing each individual internal connection, organizations can authorize internal connections for a class of components with common characteristics and/or configurations, for example, all digital printers, scanners, and copiers with a specified processing, storage, and transmission capability or all smart phones with a specific baseline configuration.
RELATED CONTROLS: CA-9
CA-9 (1) INTERNAL SYSTEM CONNECTIONS | SECURITY COMPLIANCE CHECKS
The information system performs security compliance checks on constituent system components prior to the establishment of the internal connection.
Security compliance checks may include, for example, verification of the relevant baseline configuration.
