Fix Recommendation

Change the permissions of the --client-ca-file to "644" by executing the command:

chown 644 <kubelet --client--ca-file argument location>.

Check Contents

Change to the /etc/sysconfig/ directory on the Kubernetes Master Node. Run command:

more kubelet
--client-ca-file argument
Note certificate location

If the ca-file argument location file has permissions more permissive than "644", this is a finding.
