- AC-24: Access Control Decisions
[Assignment: Establish procedures, Implement mechanisms] to ensure [Assignment: organization-defined access control decisions] are applied to each access request prior to access enforcement.
Access control decisions (also known as authorization decisions) occur when authorization information is applied to specific accesses. In contrast, access enforcement occurs when systems enforce access control decisions. While it is common to have access control decisions and access enforcement implemented by the same entity, it is not required, and it is not always an optimal implementation choice. For some architectures and distributed systems, different entities may make access control decisions and enforce access.
AC-24(1): Transmit Access Authorization Information
Transmit [Assignment: organization-defined access authorization information] using [Assignment: organization-defined controls] to [Assignment: organization-defined systems] that enforce access control decisions.
AC-24(2): No User or Process Identity
Enforce access control decisions based on [Assignment: organization-defined security or privacy attributes] that do not include the identity of the user or process acting on behalf of the user.
