# The kubelet service file should have permissions of 644 or stricter
Classification:complianceFramework:cis-kubernetesControl:4.1.1 
## Description{% #description %}

Ensure that the kubelet service file has permissions of 644 or more restrictive.

## Rationale{% #rationale %}

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.

## Audit{% #audit %}

Run the following 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 644 or more restrictive.

## Remediation{% #remediation %}

Run the below command (based on the file location on your system) on the each worker node.

For example, `chmod 644 /etc/systemd/system/kubelet.service.d/10-kubeadm.conf`

## Impact{% #impact %}

None

## Default value{% #default-value %}

By default, the kubelet service file has permissions of 640.
