Discussion

The Kubernetes API Server must set enough storage to retain logs for monitoring suspicious activity and system misconfiguration, and provide evidence for Cyber Security Investigations.

Check Content

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

If the setting "audit-log-maxage" is not set in the Kubernetes API Server manifest file or it is set less than "30", this is a finding.

Fix Text

Edit the Kubernetes API Server manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Control Plane. Set the value of "--audit-log-maxage" to a minimum of "30".
