Elasticsearch Healthcare Security Configuration Guide: HIPAA‑Ready Best Practices

This guide translates HIPAA-ready security controls into concrete Elasticsearch settings you can apply today. You will enable core security, encrypt data in transit and at rest, implement Role-Based Access Control (RBAC), harden networks with IP allowlists, and operationalize audit logging, lifecycle management, and patching—building a defense-in-depth posture for PHI.

Enabling Security Features

Start by confirming the security stack is active. In modern releases, many features ship enabled, but you should explicitly set and verify them. The anchor switch is xpack.security.enabled; turn it on and secure communications across both HTTP and transport layers with TLS 1.2+.

Core configuration

# elasticsearch.yml
xpack.security.enabled: true
