```
For a component that uses this annotation, the Fiat Spring Security configuration will be applied. This does not mean that Fiat is required to be enabled, just that the whole service has Spring Security layers and filters for requests/responses.
With this annotation and Fiat disabled, the biggest difference is the ability to access the Spring Management Server endpoints (/env, /beans, /autoconfig, etc). Most of these endpoints are considered "sensitive", and therefore are disabled from an unauthenticated user requesting them over HTTP. In order to still access them, you must use HTTP Basic authentication. See http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-endpoints.html for more details.
With this annotation and Fiat enabled, @Controller invocations annotated with Fiat authorization checks will be performed and enforced. The above Management Server endpoint information still applies.
