Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations for logical access, directly stopping unauthorized actors from reaching sensitive system information.

AC-4 Information Flow Enforcement good match

Enforces information flow policies that block sensitive system data from crossing into unauthorized control spheres.

AC-6 Least Privilege good match

Limits privileges so that only the minimum necessary access is granted, reducing the chance of exposing system-level details.

SC-7 Boundary Protection partial match

Controls communications at external and key internal boundaries to keep sensitive system information inside authorized spheres.
