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(1) 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. mechanisms used to automate configuration change control are defined;
  2. approval authorities to be notified of and request approval for proposed changes to the system are defined;
  3. the time period after which to highlight changes that have not been approved or disapproved is defined;
  4. personnel to be notified when approved changes are complete is/are defined;
  5. <CM-03(01)_ODP[01] automated mechanisms> are used to document proposed changes to the system;
  6. <CM-03(01)_ODP[01] automated mechanisms> are used to notify <CM-03(01)_ODP[02] approval authorities> of proposed changes to the system and request change approval;
  7. <CM-03(01)_ODP[01] automated mechanisms> are used to highlight proposed changes to the system that have not been approved or disapproved within <CM-03(01)_ODP[03] time period>;
  8. <CM-03(01)_ODP[01] automated mechanisms> are used to prohibit changes to the system until designated approvals are received;
  9. <CM-03(01)_ODP[01] automated mechanisms> are used to document all changes to the system;
  10. <CM-03(01)_ODP[01] automated mechanisms> are used to notify <CM-03(01)_ODP[04] personnel> when approved changes to the system are completed.

Examine

[SELECT FROM: Configuration management policy; procedures addressing system configuration change control; configuration management plan; system design documentation; system architecture and configuration documentation; automated configuration control mechanisms; system configuration settings and associated documentation; change control records; system audit records; change approval requests; change approvals; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Organizational processes for configuration change control; automated mechanisms implementing configuration change control activities].

Overlays

Showing the OT/ICS overlay for the parent control CM-3 — see the CM-3(1) 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(1). 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.
