Minimize wildcard use in Roles and ClusterRoles

SrednjaNivo 1Ručni pregledopenshift

Opis

Kubernetes Roles and ClusterRoles provide access to resources based on sets of objects and actions that can be taken on those objects. It is possible to set either of these to be the wildcard "*" which matches all items. Use of wildcards is not optimal from a security perspective as it may allow for inadvertent access to be granted when new resources are added to the Kubernetes API either as CRDs or in later versions of the product. The benchmark marks this recommendation Manual.
