R1
Rule is partially adhered to:
- The @EnableZuulProxy annotation is present,
- No Authorization Server present
- No Resource Server present
It is a single entry-point, nonetheless it is not authenticating/authorizing any incoming requests.
Artifacts:
- ZuulApplication.java: Line: 8
R2
Rule is violated: No authorization or authentication present due to no authorization
R3
Rule is violated: See rule 2.
R4
Rule is violated: See rule 2.
R5
Rule is violated: See rule 2.
R6

R13
Rule is adhered to: Hystrix Circuit Breaker enabled through @EnableZuulProxy annotation.
Artifacts:
- ZuulApplication.java: Line: 9
R14
Rule is adhered to: The gateway server uses load balancing via Ribbon to access dependent services through @EnableZuulProxy annotation.
Artifacts:
- ZuulApplication.java: Line: 9
R15
This rule is not applicable: Not a service mesh deployment.
R16
Rule is adhered to:
- Registry Service (Eureka Server) with @EnableEurekaServer present.
- Started in Docker Container through Compose, thus deployable on dedicated server
Artifacts:
R17
Rule is violated: No HTTP basic password listed in any YML-Configuration of format username:password@here-location-of-eureka-server at “eureka.client.serviceUrl.defaultZone”.
Artifacts:
