Fix Recommendation

Edit any manifest files or kubelet config files that contain the feature-gates setting with DynamicAuditing set to "true". Set the flag to "false" or remove the "DynamicAuditing" setting completely. Restart the kubelet service if the kubelet config file if the kubelet config file is changed.

Check Contents

On the Master node, change to the manifests' directory at /etc/kubernetes/manifests and run the command:

grep -i feature-gates *

Review the feature-gates setting, if one is returned.

If the feature-gates setting is available and contains the DynamicAuditing flag set to "true", this is a finding.

Change to the directory /etc/sysconfig on the Master and each Worker Node and execute the command:

grep -i feature-gates kubelet

Review every feature-gates setting that is returned.

If any feature-gates setting is available and contains the "DynamicAuditing" flag set to "true", this is a finding.
