Ensure that the API server pod specification file has permissions of 644 or more restrictive

Rationale:

The API server pod specification file controls various parameters that set the behavior of 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.

Audit: Run the below command (based on the file location on your system) on the master node. For example,

stat -c %a /etc/kubernetes/manifests/kube-apiserver.yaml

Verify that the permissions are 644 or more restrictive. Remediation: Run the below command (based on the file location on your system) on the master node.For example,

chmod 644 /etc/kubernetes/manifests/kube-apiserver.yaml
