2.2.5 Ensure that the proxy kubeconfig file permissions are set to 644 or more restrictive

Information

If 'kube-proxy' is running, ensure that the proxy kubeconfig file has permissions of '644' or more restrictive.

Rationale:

The 'kube-proxy' kubeconfig file controls various parameters of the 'kube-proxy' service in the worker node. 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 each worker node. For example,

chmod 644
