NIST SP 800-53 Rev. 5 MA-6(3) — Automated Support For Predictive Maintenance

What this control requires

The control mandates transferring predictive Maintenance data to a Maintenance management system using organization-defined automated mechanisms. These systems maintain databases of equipment condition data to automate Maintenance planning, execution, and reporting, enhancing efficiency and system reliability. This control supports the Computerized Maintenance Management System capability within the Maintenance family.

In plain English

The control mandates transferring predictive Maintenance data to a Maintenance management system using organization-defined automated mechanisms. In practice, this means you can prove you policy management-level controls on a defined cadence.

Why it matters

SP 800-53 is the catalogue every U.S. federal authorisation (FedRAMP, FISMA, CMMC) and most regulated industries point at. A missing control surfaces as a Plan of Action & Milestones (POA&M) item that an Authorizing Official must approve before the Authority To Operate is granted or renewed.

What an auditor looks for

A 3PAO (FedRAMP) or Independent Assessor (NIST RMF) tests against NIST SP 800-53A assessment procedures. For each control they expect a documented implementation that addresses every assessment objective (Examine, Interview, Test) and an implementation summary in the System Security Plan.

Within Maintenance, the assessor will trace your implementation back to the catalogue reference (Control MA-6(3)) and look for objective evidence on the latest two assessment cycles.

How to implement

Policy Management

Docs. Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

Operational checklist

• Policy. Document the trigger, the owner and the cadence.
• Data. Document the trigger, the owner and the cadence.
• Maintenance. Document the trigger, the owner and the cadence.
• System. Document the trigger, the owner and the cadence.
• Control. Document the trigger, the owner and the cadence.
• Scope: management, organization, system, databases, maintenance, capability, predictive maintenance, systems.

Evidence to collect

• Policy Document. A signed and version-controlled policy / standard / procedure document.

Signed policy or standard documents the safeguard. Focus: Automated Support For Predictive Maintenance.

Common pitfalls

• Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.
