Discussion (NIST Supplemental Guidance)

System components that are not assigned to a system may be unmanaged, lack the required protection, and become an organizational vulnerability.

Implementation Guidance

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-8(9) 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. personnel or roles from which to receive an acknowledgement is/are defined;
  2. system components are assigned to a system;
  3. an acknowledgement of the component assignment is received from <CM-08(09)_ODP personnel or roles>.

Examine

[SELECT FROM: Configuration management policy; procedures addressing system component inventory; configuration management plan; system security plan; system design documentation; system component inventory; change control records; acknowledgements of system component assignments; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with component inventory management responsibilities; system owner; organizational personnel with information security responsibilities; system/network administrators].

Test

[SELECT FROM: Organizational processes for assigning components to systems; organizational processes for acknowledging assignment of components to systems; mechanisms implementing assignment of components to the system; mechanisms implementing acknowledgment of assignment of components to the system].

Overlays

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.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CM-8(9). 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.
