|---|---|
| 1.2.1 | {{site.data.keyword.openshiftlong_notm}} utilizes RBAC for cluster protection, but allows anonymous discovery, which is considered reasonable per CIS Kubernetes Benchmark{: external}. |
| 1.2.3 | OpenShift employs other mitigating controls{: external} to restrict service external IPs. |
| 1.2.9 | {{site.data.keyword.openshiftlong_notm}} does not enable the EventRateLimit{: external} admission controller since it is a Kubernetes alpha feature. |
| 1.2.11 | {{site.data.keyword.openshiftlong_notm}} does not enable the AlwaysPullImages{: external} admission controller since it overrides a container's _imagePullPolicy_ and may impact performance. |
| 1.2.17 | {{site.data.keyword.openshiftlong_notm}} can optionally enable Kubernetes API server auditing. |
| 1.2.27 | {{site.data.keyword.openshiftlong_notm}} can optionally enable a Kubernetes Key Management Service (KMS) provider. |
