Requirements NIST SOURCE

Prevent or restrict changes to the configuration of the system under the following circumstances: [circumstances].

Discussion (NIST Supplemental Guidance)

System configuration changes can adversely affect critical system security and privacy functionality. Change restrictions can be enforced through automated mechanisms.

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(8) 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 circumstances under which changes are to be prevented or restricted are defined;
  2. changes to the configuration of the system are prevented or restricted under <CM-03(08)_ODP circumstances>.

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 component inventory; system audit records; system security plan; other relevant documents or records].

Overlays

Showing the OT/ICS overlay for the parent control CM-3 — see the CM-3(8) entries within each baseline below.

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

LOW

Not applicable at this tier.

MODERATE

  • Base control: Included (matches standard baseline)
  • Included: (2) (4)

HIGH

  • Base control: Included (matches standard baseline)
  • Included: (1) (2) (4) (6)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CM-3(8). 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.
