Requirements NIST SOURCE

Review changes to the system [frequency] or when [circumstances] to determine whether unauthorized changes have occurred.

Discussion (NIST Supplemental Guidance)

Indications that warrant a review of changes to the system and the specific circumstances justifying such reviews may be obtained from activities carried out by organizations during the configuration change process or continuous monitoring process.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for CM-3(7) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. the frequency at which changes are to be reviewed is defined;
  2. the circumstances under which changes are to be reviewed are defined;
  3. changes to the system are reviewed <CM-03(07)_ODP[01] frequency> or when <CM-03(07)_ODP[02] circumstances> to determine whether unauthorized changes have occurred.

Examine

[SELECT FROM: Configuration management policy; procedures addressing system configuration change control; configuration management plan; change control records; system architecture and configuration documentation; system configuration settings and associated documentation; system audit records; system component inventory; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with configuration change control responsibilities; organizational personnel with security responsibilities; system/network administrators; members of change control board or similar].

Test

[SELECT FROM: Organizational processes for configuration change control; mechanisms implementing audit records for changes].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CM-3(7). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
