Requirements NIST SOURCE

Monitor the use of maintenance tools that execute with increased privilege.

Discussion (NIST Supplemental Guidance)

Maintenance tools that execute with increased system privilege can result in unauthorized access to organizational information and assets that would otherwise be inaccessible.

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 MA-3(5) 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. the use of maintenance tools that execute with increased privilege is monitored.

Examine

[SELECT FROM: Maintenance policy; procedures addressing system maintenance tools; system maintenance tools and associated documentation; list of personnel authorized to use maintenance tools; maintenance tool usage records; 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 processes for restricting the use of maintenance tools; organizational process for monitoring maintenance tools and maintenance tool usage; mechanisms monitoring the use of maintenance tools].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for MA-3(5). 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.
