CM-9 Configuration Management

Configuration Management Plan

Medium Risk Moderate Low Cost

CM-9 requires developing, documenting, and implementing configuration management plans for the system that address roles, responsibilities, configuration items, baselines, change processes, and tools — and that protect CM plans from unauthorized disclosure. For healthcare, each major ePHI system (EHR, imaging, identity) needs a practical CM plan so patches, parameter changes, and releases do not silently break security or clinical workflows.

Control Objective

Maintain system-specific configuration management plans that make baselines, change control, and ownership explicit for platforms that process or protect ePHI.

Implementation Guidance

  1. Identify systems requiring CM plans (tier-1 ePHI and supporting infrastructure).
  2. Document CM roles: configuration manager, CAB liaison, clinical informatics approvers.
  3. List configuration items (OS, apps, security settings, interface configs, cloud tenant settings).
  4. Define baseline identification, change categories, and approval paths including emergency changes.
  5. Specify tools (ITSM, IaC, EHR migration workbench) and evidence locations.
  6. Protect plans — they reveal hardening and topology details.
  7. Review plans with major releases and at least annually.
  8. Align each CM-9 plan to enterprise CM-1 policy.

Real-World Use Cases

How this control shows up in healthcare and HIPAA-covered environments.

EHR upgrade from N to N+1

CM-9 plan defines which configuration items are frozen, who approves security parameter changes, and how baselines are re-established post-upgrade.

Identity provider cutover

Plan documents conditional access baselines and change ownership so MFA policies are not altered ad hoc during migration.

Imaging archive cloud move

CM plan covers storage lifecycle settings and interface endpoints as configuration items under change control.

Best Practices

  • One living CM plan per major system/enclave.
  • Explicit clinical approval for workflow-impacting configs.
  • Emergency change appendix.
  • Tooling and evidence paths named.
  • Restricted plan distribution.
  • Sync with PL-2 and CA monitoring.

Common Gaps & Violations

  • Enterprise CM policy exists but no system CM plans.
  • Plans list roles only — no configuration items.
  • Cloud tenant settings omitted as CIs.
  • Plans outdated after platform replacement.
  • Unrestricted wiki posts of hardening details.

Required Documentation

  • CM plans for major ePHI systems
  • Configuration item inventories referenced by plans
  • Change process mapping inside plans
  • Review/approval records
  • Access controls on plan repositories

How to Test & Validate

  1. Select a tier-1 ePHI system; obtain its CM-9 plan.
  2. Verify configuration items and baselines are identified.
  3. Confirm roles match actual CAB participants.
  4. Trace a recent change to the plan’s process.
  5. Check plan repository permissions.

Audit Considerations

Assessors distinguish generic CM policy from system-level planning. Missing CM-9 plans leave EHR change evidence without a governing system narrative.

HIPAA Mapping

How this NIST control supports HIPAA Security Rule expectations.

  • 164.308(a)(1) Risk Management — configuration-driven risks need planned control.
  • 164.312(c) Integrity — planned CM protects against improper alteration of systems holding ePHI.
  • 164.308(a)(8) Evaluation — evaluations need known configuration processes.
  • 164.316 Policies and procedures — CM plans document how procedures apply to a system.

Compliance Tips

  • Start CM-9 with EHR, IdP, and HIE gateway — highest impact first.
  • Reuse a template so plans stay consistent for auditors.
  • Trigger CM plan updates from the same release train as PL-2.

Frequently Asked Questions

Is a CAB charter enough for CM-9?

No. CM-9 needs system-specific plans covering CIs, baselines, and tools — not only enterprise change meetings.

Do SaaS EHRs need CM-9?

Yes for the configuration items you control (roles, audit settings, integrations, tenant security).

How does CM-9 relate to CM-3?

CM-9 plans the CM program for a system; CM-3 executes configuration change control day to day.
