Requirements NIST SOURCE

Check media containing diagnostic and test programs for malicious code before the media are used in the system.

Discussion (NIST Supplemental Guidance)

If, upon inspection of media containing maintenance, diagnostic, and test programs, organizations determine that the media contains malicious code, the incident is handled consistent with organizational incident handling policies and procedures.

Engineering Interpretation

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

No engineering interpretation has been authored for MA-3(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. media containing diagnostic and test programs are checked for malicious code before the media are used in the system.

Examine

[SELECT FROM: Maintenance policy; procedures addressing system maintenance tools; system maintenance tools and associated documentation; maintenance records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system maintenance responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational process for inspecting media for malicious code; mechanisms supporting and/or implementing the inspection of media used for maintenance].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for MA-3(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.
