Automated Plan of Action Tracking
High Risk
Complex
High Cost
CA-5(2) (Automated Plan of Action Tracking) enhances base CA-5 within the NIST Assessment, Authorization, and Monitoring family. Base CA-5 sets the foundational expectation; this enhancement adds specificity: This enhancement strengthens CA-5 with requirements for automated plan of action tracking in environments that create, receive, maintain, or transmit ePHI. Covered entities and business associates apply it to security assessments, authorizations, continuous monitoring, and POA&M tracking for systems that handle ePHI.
Control Objective
Implement Automated Plan of Action Tracking so organization-defined assessment, authorization, and monitoring safeguards operate consistently on systems and networks that handle ePHI, with measurable evidence for HIPAA and NIST assessments.
Implementation Guidance
- Map CA-5(2) to systems in scope (EHR, imaging, lab, pharmacy, billing, identity, backups, and BA connections).\n2. Translate “Automated Plan of Action Tracking” into technical settings, procedures, or architecture patterns owned by named roles.\n3. Prefer enforceable controls (config, automation, mediation) over awareness-only measures where feasible.\n4. Integrate with change, incident, and downtime processes so clinical operations are not surprised.\n5. Log and retain evidence of operation (tickets, configs, test results) aligned to audit needs.\n6. Include vendors/BAs in contracts and connection standards when they touch the control surface.\n7. Test after major EHR, network, or cloud changes — upgrades often reset protections.\n8. Review exceptions at least quarterly; expire “temporary” holes that expose ePHI paths.
Real-World Use Cases
How this control shows up in healthcare and HIPAA-covered environments.
Best Practices
- Name an owner for CA-5(2) in the SSP control matrix.\n- Favor system enforcement on ePHI paths over informal email approval.\n- Measure coverage: percent of in-scope clinical systems where the enhancement operates.\n- Review exceptions quarterly with security and clinical informatics.\n- Feed relevant events to SIEM with a named use case.\n- Keep a one-page evidence pack (config + sample log + last test) ready for assessors.
Common Gaps & Violations
- Policy cites CA-5(2) but production EHR/network paths show no enforcement of automated plan of action tracking.\n- Permanent exceptions with no expiry for vendors or “special” clinics.\n- Control implemented only on corporate IT — clinical devices and interfaces omitted.\n- No logs or test records; reliance on tribal knowledge.\n- Major upgrade silently disabled the enhancement.
Required Documentation
- Procedure/standard for Automated Plan of Action Tracking (CA-5(2))\n- Architecture or configuration baselines showing enforcement points\n- Exception register with owners and expiry\n- Sample logs, alerts, or test results\n- Training or runbook references for clinical/IT operators
How to Test & Validate
- Attempt a prohibited or out-of-policy action related to automated plan of action tracking; confirm block, alert, or required workflow.\n2. Complete an authorized clinical/IT path; confirm success and logging.\n3. Sample open exceptions for approval and expiry.\n4. Verify at least one EHR-adjacent and one BA/vendor path are in scope.\n5. Confirm evidence retained for the last 90 days (or per policy).
Audit Considerations
Assessors look for operating evidence of Automated Plan of Action Tracking on systems touching ePHI — configs, logs, restore/DR artifacts, or failed-test results — not only a policy paragraph referencing CA-5(2).
HIPAA Mapping
How this NIST control supports HIPAA Security Rule expectations.
- 164.308(a)(8) Evaluation — periodic technical and nontechnical evaluation of security measures for ePHI.\n- 164.308(a)(1)(ii)(A) Risk Analysis — assessments inform how ePHI is at risk.\n- 164.308(a)(1)(ii)(B) Risk Management — authorize and monitor controls that reduce ePHI risk.\n- 164.316(b)(1) Documentation — retain assessment and authorization evidence as required.
Compliance Tips
- List CA-5(2) explicitly in the system security plan with system inventory references.\n- Prioritize emergency department, inpatient EHR, and remote access paths first.\n- Bundle evidence with related HIPAA evaluation, integrity, or workforce-security narratives where they overlap.
