Spring Boot Actuator is a double-edged sword: its endpoints provide invaluable insights into your application’s health, metrics, and environment but can also expose critical vulnerabilities if misconfigured. A single unprotected /env or /heapdump endpoint can leak secrets, crash your app, or even grant attackers full control.

Let’s harden your Actuator setup with role-based access, network policies, and encryption—while keeping your ops team productive.

Why Actuator Security Matters

• Sensitive Data Exposure: /env reveals configuration properties (including passwords).
• Service Disruption: /shutdown can terminate your app.
• Exploitable Metrics: /heapdump may expose memory-based attacks.

Let’s fix this.

Step 1: Role-Based Access Control (RBAC)

Assign Roles to Actuator Endpoints

Use Spring Security to restrict access to specific roles (e.g., ACTUATOR, ADMIN).
