Ensure that the --audit-log-maxage argument is set to 30 or as appropriate (API Server)

Retain the logs for at least 30 days or as appropriate. Retaining logs for at least 30 days ensures that you can go back in time and investigate or correlate any events. Set your audit log retention period to 30 days or as per your business requirements.

GSL LOGIC

KubernetesPod where labels contain [value='kube-apiserver'] and namespace = 'kube-system' should have spec.containers with [parsedArgs contain [key like 'audit-log-maxage' and value >= 30]]

REMEDIATION

Edit the API server pod specification file $apiserverconf
on the master node and set the --audit-log-maxage parameter to 30 or
as an appropriate number of days: --audit-log-maxage=30
