Discussion (NIST Supplemental Guidance)

Hardware components provide the foundation for organizational systems and the platform for the execution of authorized software programs. Managing the inventory of hardware components and controlling which hardware components are permitted to be installed or connected to organizational systems is essential in order to provide adequate security.

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-7(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. hardware components authorized for system use are defined;
  2. frequency at which to review and update the list of authorized hardware components is defined;
  3. <CM-07(09)_ODP[01] hardware components> are identified;
  4. the use or connection of unauthorized hardware components is prohibited;
  5. the list of authorized hardware components is reviewed and updated <CM-07(09)_ODP[02] frequency>.

Examine

[SELECT FROM: Configuration management policy; network connection policy and procedures; configuration management plan; system security plan; system design documentation; system component inventory; system audit records; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Organizational process for approving execution of binary or machine-executable code; mechanisms supporting and/or implementing the prohibition of binary or machine-executable code].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for CM-7(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.
