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.

Technical Implementation:
- •Describe the specific technical mechanisms or controls used to enforce AC-24 requirements.
- •What automated tools, systems, or technologies are deployed to implement AC-24?
- •How is AC-24 integrated into your system architecture and overall security posture?
- •What configuration settings, parameters, or technical specifications enforce AC-24 requirements?
