1.4.1 Ensure that the API server pod specification file permissions are set to 644 or more restrictive

Information

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.

Solution

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

Impact:

None
