EHR security patch weekend
CM-1 procedures require CAB approval, downtime communication to nursing, and baseline update after successful patching.
Configuration Management Policy and Procedures
High Risk
Moderate
Low Cost
CM-1 requires configuration management policy and procedures addressing purpose, scope, roles, management commitment, coordination, and compliance, plus procedures to implement the CM family. For healthcare, CM-1 governs how EHR environments, clinical workstations, medical device network configs, and cloud tenants are baselined and changed without introducing ePHI exposure or downtime.
Control Objective
Establish policy and procedures that control secure baselines, inventories, and changes for systems and components that protect or process ePHI.
Implementation Guidance
- Publish CM-1 policy covering servers, endpoints, network devices, EHR configs, and approved cloud settings.
- Define configuration control board / change advisory roles including clinical informatics when workflows break.
- Require secure baselines (CIS/vendor hardening) for ePHI-related platforms.
- Mandate documented changes with backout plans for production clinical systems.
- Prohibit unauthorized local admin and shadow configuration on nursing stations.
- Align CM-1 with CM-2 baselines, CM-3 changes, CM-6 settings, and CM-8 inventory.
- Review policy annually and after major platform migrations.
- Include emergency change procedures that still capture post-hoc documentation.
Real-World Use Cases
How this control shows up in healthcare and HIPAA-covered environments.
Clinic installs unapproved browser toolbar
Policy forbids local configuration drift; endpoint management reverts settings and tickets the manager — protecting against credential theft to ePHI apps.

Network change follows CM-1: ticket, dual review, and documentation of the ePHI data path.
Best Practices
- Written baselines for critical clinical systems.
- CAB with clinical representation.
- Emergency change path with after-action docs.
- Drift detection on hardened builds.
- Inventory linkage before changes.
- Cloud tenant config-as-code where feasible.
Common Gaps & Violations
- Production EHR parameter changes with no ticket.
- Baselines exist only for corporate IT, not clinical devices.
- Emergency changes never documented.
- No owner for cloud EHR security settings.
- Policy silent on medical device network changes.
Required Documentation
- Configuration management policy (CM-1)
- Change management procedures
- Baseline ownership matrix
- CAB charter / membership
- Policy review records
How to Test & Validate
- Verify CM-1 policy is approved and current.
- Sample production changes for ticketed approval.
- Confirm baselines exist for a critical ePHI system.
- Review an emergency change for post-documentation.
- Interview bedside IT support on unauthorized change rules.
Audit Considerations
Configuration discipline underpins integrity and availability of ePHI systems. Auditors correlate outages and vulnerabilities to weak change governance rooted in missing or stale CM-1.
HIPAA Mapping
How this NIST control supports HIPAA Security Rule expectations.
- 164.310(a)(2)(iii) Access Control & Validation — facility procedures often pair with config control for sensitive areas.
- 164.312(a) Access Control / 164.312(c) Integrity — configuration protects against improper alteration of ePHI.
- 164.308(a)(1) Risk Management — insecure configurations are identified and treated risks.
- 164.316 Policies and procedures — document CM policy and updates.
Compliance Tips
- Put “ePHI impact” as a required field on every change form.
- Sync CM-1 review with EHR upgrade calendar.
- Publish a short “no local admin on clinical endpoints” standard under CM-1.
Frequently Asked Questions
Does CM-1 apply to SaaS EHR settings?
Yes — tenant security and workflow configurations that affect ePHI access are in scope even when infrastructure is vendor-managed.
How does CM-1 relate to CM-9?
CM-1 is the overarching CM policy; CM-9 addresses configuration management plans for specific systems.
Who approves clinical workflow config changes?
Policy should require both technical change approval and clinical/informatics ownership for patient-care workflows.
