Remediation Method 1:
If configuring via the Kubelet config file, you first need to locate the file.
To do this, SSH to each node and execute the following command to find the kubelet
process:
ps -ef | grep kubelet
The output of the above command provides details of the active kubelet process, from
which we can see the location of the configuration file provided to the kubelet service
with the --config argument. The file can be viewed with a command such as more or
less, like so:
sudo less /home/kubernetes/kubelet-config.yaml
Disable Anonymous Authentication by setting the following parameter:
"authentication": { "anonymous": { "enabled": false } }
Remediation Method 2:
If using executable arguments, edit the kubelet service file on each worker node and
ensure the below parameters are part of the KUBELET_ARGS variable string.
For systems using systemd, such as the Amazon EKS Optimised Amazon Linux or
Bottlerocket AMIs, then this file can be found at
/etc/systemd/system/kubelet.service.d/10-kubelet-args.conf. Otherwise,
you may need to look up documentation for your chosen operating system to determine
which service manager is configured:
--anonymous-auth=false
For Both Remediation Steps:
Based on your system, restart the kubelet service and check the service status.
The following example is for operating systems using systemd, such as the Amazon
EKS Optimised Amazon Linux or Bottlerocket AMIs, and invokes the systemctl
command. If systemctl is not available then you will need to look up documentation for
your chosen operating system to determine which service manager is configured:

Next, set the Authorization Mode to Webhook by setting the following parameter:

Remediation Method 1:
If modifying the Kubelet config file, edit the kubelet-config.yaml file
/etc/kubernetes/kubelet/kubelet-config.yaml and set the below parameter to
true
"RotateCertificate":true
Additionally, ensure that the kubelet service file
/etc/systemd/system/kubelet.service.d/10-kubelet-args.conf does not set the --RotateCertificate
executable argument to false because this would override the Kubelet
config file.
Remediation Method 2:
If using executable arguments, edit the kubelet service file

worker node and add the below parameter at the end of the KUBELET_ARGS variable
string.

running kubelet.
