Check Text (C-242463r961863_chk)
Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Control Plane. Run the command:
grep -i audit-log-maxbackup *
If the setting "audit-log-maxbackup" is not set in the Kubernetes API Server manifest file or it is set less than "10", this is a finding.
Fix Text (F-45696r863929_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-maxbackup" to a minimum of "10".
