Verify Permissions on the OpenShift Controller Manager Kubeconfig File
An XCCDF Rule
Description
To properly set the permissions of /etc/kubernetes/static-pod-resources/kube-controller-manager-pod-*/configmaps/controller-manager-kubeconfig/kubeconfig, run the command:
$ sudo chmod 0600 /etc/kubernetes/static-pod-resources/kube-controller-manager-pod-*/configmaps/controller-manager-kubeconfig/kubeconfig
warning alert: Dependency Warning
This rule is only applicable for nodes that run the Kubernetes Controller Manager service.
The aforementioned service is only running on the nodes labeled
"master" by default.
Rationale
The Controller Manager's kubeconfig contains information about how the component will access the API server. You should restrict its file permissions to maintain the integrity of the file. The file should be writable by only the administrators on the system.
