Requirements NIST SOURCE

Perform preventive maintenance on [system components] at [time intervals].

Discussion (NIST Supplemental Guidance)

Preventive maintenance includes proactive care and the servicing of system components to maintain organizational equipment and facilities in satisfactory operating condition. Such maintenance provides for the systematic inspection, tests, measurements, adjustments, parts replacement, detection, and correction of incipient failures either before they occur or before they develop into major defects. The primary goal of preventive maintenance is to avoid or mitigate the consequences of equipment failures. Preventive maintenance is designed to preserve and restore equipment reliability by replacing worn components before they fail. Methods of determining what preventive (or other) failure management policies to apply include original equipment manufacturer recommendations; statistical failure records; expert opinion; maintenance that has already been conducted on similar equipment; requirements of codes, laws, or regulations within a jurisdiction; or measured values and performance indications.

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-6(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. system components on which preventive maintenance is to be performed are defined;
  2. time intervals within which preventive maintenance is to be performed on system components are defined;
  3. preventive maintenance is performed on <MA-06(01)_ODP[01] system components> at <MA-06(01)_ODP[02] time intervals>.

Examine

[SELECT FROM: Maintenance policy; procedures addressing system maintenance; service provider contracts; service-level agreements; maintenance records; list of system components requiring preventive maintenance; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Organizational processes for preventive maintenance; mechanisms supporting and/or implementing preventive maintenance].

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

LOW

Not applicable at this tier.

MODERATE

  • Base control: Included (matches standard baseline)

HIGH

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for MA-6(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.
