Requirements NIST SOURCE

Obtain software and data employed during system component and service refreshes from the following trusted sources: [trusted sources].

Discussion (NIST Supplemental Guidance)

Trusted sources include software and data from write-once, read-only media or from selected offline secure storage facilities.

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 SI-14(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. trusted sources to obtain software and data for system component and service refreshes are defined;
  2. the software and data employed during system component and service refreshes are obtained from <SI-14(01)_ODP trusted sources>.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing non-persistence for system components; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel responsible for obtaining component and service refreshes from trusted sources; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational processes for defining and obtaining component and service refreshes from trusted sources; automated mechanisms supporting and/or implementing component and service refreshes].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-14(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.
