Discussion

The Kubernetes kubelet agent registers nodes with the API server and performs health checks to containers within pods. If this file can be modified, the information system would be unaware of pod or container degradation.

Check Content

Review the permissions of the Kubernetes config.yaml by using the command:

stat -c %a /var/lib/kubelet/config.yaml

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

Fix Text

Change the permissions of the config.yaml to "644" by executing the command:

chmod 644 /var/lib/kubelet/config.yaml
