 = Disabling the automatic creation of RBAC resources
 
+[role="_abstract"]
 The default installation of the {pipelines-title} Operator creates multiple Role Based Access Control (RBAC) resources for all namespaces in the cluster, except the namespaces matching the `^(openshift|kube)-*` regular expression pattern. Among these RBAC resources, the `pipelines-scc-rolebinding` SCC role binding resource is a potential security issue, because the associated `pipelines-scc` Security Context Constraint has `RunAsAny` privilege. 
 
-To disable the automatic creation of cluster-wide RBAC resources after the {pipelines-title} Operator is installed, cluster administrators can set the `createRbacResource` parameter to `false` in the cluster level `TektonConfig` custom resource.
