Classified Information Requiring Special Protection
PS-6(2) (Classified Information Requiring Special Protection) enhances base PS-6 within the NIST Personnel Security family. Base PS-6 sets the foundational expectation; this enhancement adds specificity: Verify that access to classified information requiring special protection is granted only to individuals who: Have a valid access authorization that is demonstrated by assigned official government duties; Satisfy associated personnel security criteria; and Have read, understood, . Covered entities and business associates apply it to screening, onboarding, transfers, terminations, and sanctions for workforce and contractors who can reach ePHI.
Control Objective
Implement Classified Information Requiring Special Protection so organization-defined personnel security safeguards operate consistently on systems and networks that handle ePHI, with measurable evidence for HIPAA and NIST assessments.
Implementation Guidance
- Map PS-6(2) to systems in scope (EHR, imaging, lab, pharmacy, billing, identity, backups, and BA connections).\n2. Translate “Classified Information Requiring Special Protection” 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 PS-6(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 PS-6(2) but production EHR/network paths show no enforcement of classified information requiring special protection.\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 Classified Information Requiring Special Protection (PS-6(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 classified information requiring special protection; 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 Classified Information Requiring Special Protection on systems touching ePHI — configs, logs, restore/DR artifacts, or failed-test results — not only a policy paragraph referencing PS-6(2).
HIPAA Mapping
How this NIST control supports HIPAA Security Rule expectations.
- 164.308(a)(3) Workforce Security — authorize, supervise, clear, and terminate workforce access to ePHI.\n- 164.308(a)(3)(ii)(B) Workforce Clearance Procedure — determine access appropriateness.\n- 164.308(a)(3)(ii)(C) Termination Procedures — end access when employment ends.\n- 164.308(a)(1)(ii)(C) Sanction Policy — apply appropriate sanctions for violations.
Compliance Tips
- List PS-6(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.
