Opis

Kubernetes provides the option to use client certificates for user authentication. However as there is no way to revoke these certificates when a user leaves an organization or loses their credential, they are not suitable for this purpose. It is not possible to fully disable client certificate use within a cluster as it is used for component to component authentication. The benchmark marks this recommendation Manual.

Configure an identity provider for the OpenShift cluster following the OpenShift documentation. Once an identity provider has been defined, you can use RBAC to define and apply permissions. After you define an identity provider and create a new cluster-admin user you can reduce the attack surface by removing the default kubeadmin user.
