Spring Boot Actuator: What to Expose, What to Hide, and What to Check Before Adding Endpoints

The Spring Boot Actuator configuration in many tutorials enables all endpoints by default, but this can expose sensitive information. It's essential to have a clear policy for what to expose, restrict, and for whom. Review the official documentation and consider factors like endpoint relevance, port separation, and access control before adding endpoints. Explicitly configure what to expose and secure endpoints as needed.
