GSL LOGIC

KubernetesPod where labels contain [value='kube-apiserver'] and namespace = 'kube-system' should have spec.containers with [parsedArgs contain [key like 'audit-log-maxbackup' and value >= 10]]

REMEDIATION

Edit the API server pod specification file $apiserverconf
on the master node and set the --audit-log-maxbackup parameter to 10
or to an appropriate value.
--audit-log-maxbackup=10

Pods

Pods are the smallest deployable units of computing that can be created and managed in Kubernetes. A Pod is a group of one or more containers (such as Docker containers), with shared storage/network, and a specification for how to run the containers.
