HIPAA Technical Safeguards Requirements: Audit-Ready Implementation and Evidence Checklist

Use this guide to implement the HIPAA Technical Safeguards and assemble audit-ready evidence. Each section explains what to build for Electronic Protected Health Information (ePHI) and exactly what artifacts to prepare for auditors.

Access Control Mechanisms

Implement controls that limit ePHI access to authorized users and processes. Under 45 CFR 164.312(a), unique identification and emergency access are required; automatic logoff and encryption/decryption are addressable and must be implemented or formally justified.

Implementation essentials

• Unique User Identification: assign one ID per person; prohibit shared accounts and default credentials.
• Role- and attribute-based access: map least-privilege access to job functions; segregate duties for high-risk actions.
• Emergency access (“break-glass”): define who can override controls, how access is logged, and how post-event review occurs.
• Automatic Logoff: enforce inactivity timeouts for applications, databases, and workstations handling ePHI.
• Encryption Standards (addressable): apply encryption/decryption for data at rest (e.g., full-disk, database, storage-level) with documented key management.
• Privileged access management: vault admin credentials, require approvals for elevation, and record sessions.

Audit-ready evidence checklist

• Access control policy and procedures (Security Policy Documentation) referencing Unique User Identification and Automatic Logoff.
• Current access matrix by role and system; recent quarterly access review sign-offs.
• Samples of “break-glass” events with reviewer attestation and remediation notes.
• Screenshots or config exports showing timeout policies and session locks.
• Encryption architecture diagram; key lifecycle SOPs and KMS configuration excerpts.
• User provisioning/deprovisioning tickets proving timely onboarding and termination.

Audit Control Procedures

Establish mechanisms that record and examine system activity for systems that create, receive, maintain, or transmit ePHI. Audit controls are required under 45 CFR 164.312(b).

Implementation essentials

• Audit Trail Systems: centralize logs (EHRs, apps, databases, endpoints, firewalls, cloud services) in a SIEM.
• Time synchronization: use reliable time sources to preserve log sequence and correlation integrity.
• Coverage and content: record user IDs, timestamps, source IPs, event types, and object identifiers for ePHI access.
• Alerting and response: define rules for anomalous access and failed authentication spikes; document incident handling.
• Retention and protection: set retention consistent with business and legal needs; many align to six years for related documentation.

Audit-ready evidence checklist

• Logging and monitoring procedures describing sources, retention, and review cadence.
• SIEM dashboards and sample correlated incidents with investigation notes.
• Daily/weekly log review records, including exceptions and resolutions.
• Proof of immutable storage or write-once retention for critical audit trails.
• Change logs showing onboarding of new systems into centralized logging.

Integrity Verification Techniques

Protect ePHI from improper alteration or destruction and verify its authenticity. Integrity is required; mechanisms to authenticate ePHI are addressable under 45 CFR 164.312(c).

Implementation essentials

• Data Integrity Controls: use checksums, cryptographic hashes, and digital signatures for files and messages.
• Application controls: enforce field validation, referential integrity, and versioning of clinical records.
• Storage protections: enable WORM/immutable storage for critical logs and backups; monitor unauthorized changes.
• Backup and restoration: perform regular backups, test restores, and compare hash values pre/post restore.
• Malware and allow-list defenses: prevent tampering through endpoint protection and code integrity policies.

Audit-ready evidence checklist

• Integrity policy describing hashing, signatures, and data validation gates.
• Snapshots of checksum workflows and automated verification reports.
• Backup test results, including restore validation and hash comparisons.
• Database constraint reports and change-detection alerts with ticket links.

Person or Entity Authentication Methods

Verify that a person or entity seeking access is the one claimed. Person or entity authentication is required under 45 CFR 164.312(d).

Implementation essentials

• Authentication Protocols: implement SSO with SAML or OpenID Connect; use OAuth 2.0 for APIs; support Kerberos in enterprise environments.
• MFA everywhere: require multi-factor authentication for remote access, privileged actions, and ePHI systems.
• Unique User Identification: prohibit shared credentials; bind tokens or authenticators to individuals.
• Device and service identity: use certificates or keys for servers, services, and APIs; rotate and revoke promptly.
• Session controls: set re-authentication for sensitive actions and define lockout thresholds.

Audit-ready evidence checklist

• Authentication policy and MFA standard covering methods, enrollment, and exceptions.
• Identity provider configuration exports showing MFA enforcement and assurance levels.
• Sample authenticator life-cycle records (issuance, replacement, revocation).
• Privileged account inventory with proof of periodic review and ownership.

Transmission Security Measures

Safeguard ePHI in transit against unauthorized access and alteration. Transmission security is required; integrity controls and encryption are addressable under 45 CFR 164.312(e).

Implementation essentials

• Transmission Encryption: use current TLS (1.2 or higher) for web apps and APIs; enforce secure ciphers and certificate pinning where appropriate.
• Secure file transfer: prefer SFTP/FTPS or HTTPS-based exchange; disable insecure protocols and weak algorithms.
• Email protections: enforce TLS for mail transport; use secure portals or S/MIME/PGP when end-to-end encryption is needed.
• Network channels: protect remote access with VPN or Zero Trust network access; consider mutual TLS for service-to-service traffic.
• Integrity checks: apply MACs/signatures for payloads and enable HSTS and anti-downgrade settings on gateways.

Audit-ready evidence checklist

• Network and data flow diagrams labeling encrypted paths and trust boundaries.
• Gateway/load balancer configurations showing TLS policies and certificate details.
• Vulnerability scan results demonstrating no deprecated protocols or ciphers.
• Samples of secure email or file-transfer logs proving negotiated encryption.

Documentation of Policies and Procedures

Create and maintain Security Policy Documentation that describes how technical safeguards operate, are monitored, and are updated. Retain documentation for at least six years from creation or last effective date.

Implementation essentials

• Policy set: access control, authentication, logging, encryption, integrity, key management, and incident response.
• Procedures and standards: step-by-step SOPs for provisioning, break-glass, log review, backup/restore, and Transmission Encryption configurations.
• Governance: versioning, approvals, owner assignments, and review cycles with documented exceptions and risk acceptances.
• Training and awareness: record distribution and acknowledgments for workforce members with technical responsibilities.

Audit-ready evidence checklist

• Policy register with versions, owners, and next review dates.
• Procedure playbooks aligned to each safeguard and mapped to systems.
• Change-history showing when controls or configurations were updated and why.
• Exception and waiver logs with compensating controls and expiration dates.

Risk Assessment and Security Updates

Continuously identify, assess, and mitigate risks that could impact ePHI. Use a Risk Management Framework to guide prioritization, control selection, and verification of effectiveness.

Implementation essentials

• Risk analysis: inventory systems handling ePHI, evaluate threats and vulnerabilities, and rate inherent and residual risk.
• Risk treatment: select controls, define owners and due dates, and track through remediation to closure.
• Security updates: implement patching SLAs by severity, emergency updates, and configuration baselines with drift detection.
• Validation: conduct vulnerability scanning, penetration testing, and control assessments; remediate and re-test.
• Third-party oversight: assess vendors’ Transmission Encryption, Authentication Protocols, and Audit Trail Systems; capture evidence in due diligence files.

Audit-ready evidence checklist

• Current risk register with treatment plans and status for technical safeguards.
• Patching and vulnerability metrics, including SLA adherence and exceptions.
• Assessment reports (scans, tests) with remediation proof and retest outcomes.
• Vendor security reviews and contractual requirements tied to ePHI handling.

Conclusion

To be audit-ready, implement each safeguard with clear ownership, automate enforcement where possible, and preserve high-quality evidence. Align controls to your risk profile, document decisions, and prove—through artifacts—that ePHI is protected end to end.
