Ensure that the kubelet service file has permissions of 600 or more restrictive.
The kubelet service file controls various parameters that set the behavior of the kubelet 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.
None
Automated AAC auditing has been modified to allow CIS-CAT to input a variable for the <PATH>/<FILENAME> of the kubelet service config file.
Please set $kubelet_service_config=<PATH> based on the file location on your system for example:
export kubelet_service_config=/etc/systemd/system/kubelet.service.d/kubeadm.conf
To perform the audit manually: Run the below command (based on the file location on your system) on the each worker node. For example,
stat -c %a /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
Verify that the permissions are 600 or more restrictive.
Run the below command (based on the file location on your system) on the each worker node. For example,
chmod 600 /etc/systemd/system/kubelet.service.d/kubeadm.conf
By default, the kubelet service file has permissions of 640.
