Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly enforces authorization checks on the search index so that only users permitted to view the original documents can access indexed content.
AC-6 limits privileges so that fewer accounts can reach the index, reducing the chance that unauthorized actors obtain sensitive indexed data.
AC-16 associates sensitivity attributes with data, enabling the index to inherit and enforce the same access restrictions as the source documents.
AC-4 enforces information-flow rules that can stop sensitive data from being reachable through an improperly authorized index.

Information access restriction is the technical mechanism that prevents unauthorized index queries.
Managing access rights ensures only authorized users can reach indexed sensitive content.
Privileged access rights may be used to enforce index restrictions but are not the primary control.
Classification helps identify what must be protected but does not enforce index access limits.
Access control policies directly limit who can query or view the index.
Data leakage prevention can block unauthorized index exposure but is supplementary.
