HIPAA Compliance

Implement HIPAA Security Rule, Privacy Rule, and Breach Notification Rule requirements for systems that create, receive, maintain, or transmit electronic Protected Health Information (ePHI).

When to Use

• Building or operating systems that handle electronic Protected Health Information
• Configuring cloud infrastructure for HIPAA-eligible workloads
• Establishing Business Associate Agreements with vendors
• Implementing technical safeguards for PHI protection
• Preparing for HIPAA compliance audits or OCR investigations

Best Practices

• Conduct a thorough risk analysis annually and after significant system changes
• Use only HIPAA-eligible cloud services and sign BAAs before deploying PHI workloads
• Encrypt all PHI at rest and in transit with no exceptions
• Implement the minimum necessary standard: grant access only to the PHI needed for each role
• Maintain audit logs of all PHI access for a minimum of 6 years
• Train all workforce members on HIPAA policies at onboarding and annually
• Test contingency plans (backup restore, DR failover, emergency access) at least annually
• Track all Business Associate Agreements in a central registry with review dates
• Document every addressable specification decision (implement, alternative, or not applicable with rationale)
• Prepare breach notification templates and procedures before an incident occurs
