Discussion

The Kubernetes kubelet agent registers nodes with the API Server, mounts volume storage for pods, and performs health checks to containers within pods. If these files can be modified, the information system would be unaware of pod or container degradation. Many of the security settings within the document are implemented through this file.

Check Content

Review the permissions of the Kubernetes Kubelet conf by using the command:

stat -c %a  /etc/kubernetes/kubelet.conf

If any of the files are have permissions more permissive than "644", this is a finding.

Fix Text

Change the permissions of the Kubelet to "644" by executing the command:

chmod 644 /etc/kubernetes/kubelet.conf
