Requirements NIST SOURCE

Maintain the currency, completeness, accuracy, and availability of the inventory of system components using [organization-defined automated mechanisms].

Discussion (NIST Supplemental Guidance)

Organizations maintain system inventories to the extent feasible. For example, virtual machines can be difficult to monitor because such machines are not visible to the network when not in use. In such cases, organizations maintain as up-to-date, complete, and accurate an inventory as is deemed reasonable. Automated maintenance can be achieved by the implementation of CM-2(2) for organizations that combine system component inventory and baseline configuration activities.

Engineering Interpretation

No engineering interpretation has been authored for CM-8(2) 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. automated mechanisms used to maintain the currency of the system component inventory are defined;
  2. automated mechanisms used to maintain the completeness of the system component inventory are defined;
  3. automated mechanisms used to maintain the accuracy of the system component inventory are defined;
  4. automated mechanisms used to maintain the availability of the system component inventory are defined;
  5. <CM-08(02)_ODP[01] automated mechanisms> are used to maintain the currency of the system component inventory;
  6. <CM-08(02)_ODP[02] automated mechanisms> are used to maintain the completeness of the system component inventory;
  7. <CM-08(02)_ODP[03] automated mechanisms> are used to maintain the accuracy of the system component inventory;
  8. <CM-08(02)_ODP[04] automated mechanisms> are used to maintain the availability of the system component inventory.

Examine

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.

LOW

  • Base control: Included (matches standard baseline)

MODERATE

  • Base control: Included (matches standard baseline)
  • Included: (1) (3)

HIGH

  • Base control: Included (matches standard baseline)
  • Included: (1) (2) (3) (4)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CM-8(2). 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.
