Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Control Plane. Run the command:
grep -i audit-log-path *

If the setting audit-log-path is not set in the Kubernetes API Server manifest file or it is not set to a valid path, this is a finding.

Fix Text (F-45698r863935_fix)

Edit the Kubernetes API Server manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Control Plane. Set the value of "--audit-log-path" to valid location.
