File contents

4.1.2 Ensure that the kubelet service file ownership is set to root:root (Automated)

Profile Applicability

Level 1 - Worker Node

Description

Ensure that the kubelet service file ownership is set to root:root.

Rationale

The kubelet service file controls various parameters that set the behavior of the kubelet service in the worker node. You should set its file ownership to maintain the integrity of the file. The file should be owned by root:root.

Impact

None

Audit

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><filename> 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 %U:%G /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

Verify that the ownership is set to root:root.

Remediation

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

chown root:root /etc/systemd/system/kubelet.service.d/kubeadm.conf

Default Value

By default, kubelet service file ownership is set to root:root.
