Requirements NIST SOURCE

Require that the integrity of the following user-installed software be verified prior to execution: [user-installed software].

Discussion (NIST Supplemental Guidance)

Organizations verify the integrity of user-installed software prior to execution to reduce the likelihood of executing malicious code or programs that contains errors from unauthorized modifications. Organizations consider the source of the software, ensuring the software and updates come from authorized sources and/or sites, and the practicality of approaches to verifying software integrity, including the availability of trustworthy checksums from software developers and vendors.

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-7(12) 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. user-installed software requiring integrity verification prior to execution is defined;
  2. the integrity of <SI-07(12)_ODP user-installed software> is verified prior to execution.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing software, firmware, and information integrity; system design documentation; system configuration settings and associated documentation; integrity verification records; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel responsible for software, firmware, and/or information integrity; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Software, firmware, and information integrity verification tools; mechanisms supporting and/or implementing verification of the integrity of user-installed software prior to execution].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-7(12). 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.
