Securing Actuator Endpoints

Protect sensitive operational endpoints.

Why Actuator Needs Securing

Actuator endpoints can reveal environment variables, beans, mappings, and even heap dumps. Left open, they leak sensitive information and may allow dangerous operations like shutdown. They must be protected in production.

Minimize the Attack Surface First

Security starts with exposure. Expose only the endpoints operators truly need over HTTP, and exclude sensitive ones like env, beans, and heapdump.
