Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforces approved authorizations for logical access to configuration resources so external parties cannot alter them.

CM-5 Access Restrictions for Change good match

Enforces documented access restrictions on all changes to system configuration, directly blocking unauthorized external control of settings.

AC-6 Least Privilege good match

Limits privileges to the minimum needed, reducing the set of users who can externally modify configuration.

PR.PS-01 mostly match
prevents

Hardened configuration baselines and change controls directly limit external manipulation of settings.

ID.RA-07 partial match
prevents

Formal change and exception management catches externally driven configuration alterations.

PR.AA-05 partial match
prevents

Least-privilege access policies reduce unauthorized external modification of configuration values.

A.8.9 Configuration management full match
degrades

Configuration management directly prevents external tampering with system settings.

A.5.18 Access rights mostly match
prevents

Access rights assignment determines who may change system settings.

A.8.2 Privileged access rights mostly match
prevents

Privileged access rights reduce the number of users who can alter configuration.

A.8.3 Information access restriction mostly match
prevents

Information access restriction limits who can view or modify configuration data.

A.8.32 Change management mostly match
prevents

Change management enforces controlled, authorized modifications to settings.

A.5.15 Access control partial match
prevents

Access control policies underpin the technical restrictions on configuration changes.
