HIPAA Security Architecture for Cloud-Native EHRs
HIPAA compliance is not a checkbox. For cloud-native EHRs, it requires deliberate architecture decisions around encryption, access control, and audit logging.
Cloud changes the threat model
Traditional on-premise EHRs had a simple security perimeter. Cloud-native EHRs have no perimeter. Data flows through APIs, is stored in managed databases, and is accessed from anywhere.
The three pillars of HIPAA technical safeguards
Encryption (TLS 1.2+ in transit, AES-256 at rest), access control (RBAC with least privilege), and audit logging (immutable, queryable, retained).
