Requirements NIST SOURCE

Employ the following controls to ensure an adequate supply of [critical system components]: [controls].

Discussion (NIST Supplemental Guidance)

Adversaries can attempt to impede organizational operations by disrupting the supply of critical system components or corrupting supplier operations. Organizations may track systems and component mean time to failure to mitigate the loss of temporary or permanent system function. Controls to ensure that adequate supplies of critical system components include the use of multiple suppliers throughout the supply chain for the identified critical components, stockpiling spare components to ensure operation during mission-critical times, and the identification of functionally identical or similar components that may be used, if necessary.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for SR-5(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. controls to ensure an adequate supply of critical system components are defined;
  2. critical system components of which an adequate supply is required are defined;
  3. <SR-05(01)_ODP[01] controls> are employed to ensure an adequate supply of <SR-05(01)_ODP[02] critical system components>.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SR-5(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.
