MediumLevel 1Manual reviewopenshift

Description

Ensure that the kubeconfig file mounted into the Controller Manager has permissions of 600 or more restrictive. The benchmark marks this recommendation Manual.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

The kubeconfig file for kube-controller-manager is stored in the ConfigMap controller-manager-kubeconfig in the namespace openshift-kube-controller-manager. The kubeconfig file is referenced in the pod via hostpath and is stored in /etc/kubernetes/static-pod-resources/configmaps/controller-manager-kubeconfig/kubeconfig with permissions 600. Run the following command.

How it is fixed

Fix method: Guidance or infrastructure patch

There is no remediation for updating the permissions of the kubeconfig file. The file is owned by an OpenShift operator and any changes to the file will result in a degraded cluster state. Please do not attempt to remediate the permissions of this file.
