Mitigating Controls (NIST 800-53 r5) AI

Ensuring access decisions are applied to every request structurally prevents the product from taking unexpected paths when privileges are lacking.

A reference monitor that is always invoked guarantees privilege checks occur, eliminating the root condition for improper insufficient-privilege handling.

Access enforcement directly stops code from proceeding on insufficient privileges by applying authorization checks before resource access.

PR.AA-05 mostly match
prevents

Defining, enforcing and reviewing access permissions with least privilege directly prevents code paths that mishandle insufficient privileges.

DE.CM-09 partial match
prevents

Runtime monitoring of software and data surfaces adverse events triggered by unhandled permission failures.

PR.PS-04 partial match
prevents

Generating logs of permission-related events enables detection and analysis of improper handling.

finds

Security testing can detect missing or incorrect privilege handling.

prevents

Defines access-control policy that should prevent insufficient-privilege situations.

degrades

Specifies how access rights are granted, reviewed and revoked, directly addressing privilege handling.

degrades

Requires explicit management of privileged access rights, reducing the chance of missing privilege checks.

prevents

Secure-SDLC practices include privilege checks during design and coding.

prevents

Secure-coding standards require proper permission checks before resource access.
