Fix Recommendation

Change the permissions of kubeadm.conf to "644" by executing the command:

chmod 644 <kubeadm.conf path>

Check Contents

Review the kubeadm.conf file :

Get the path for kubeadm.conf by running:
systemctl status kubelet

Note the configuration file installed by the kubeadm is written to
(Default Location: /etc/systemd/system/kubelet.service.d/10-kubeadm.conf)
stat -c %a <kubeadm.conf path>

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