GSL LOGIC

KubernetesPod where labels contain [value='kube-apiserver'] and namespace = 'kube-system' should have spec.containers with [parsedArgs contain [key like 'authorization-mode' and value like '%RBAC%']]

REMEDIATION

Edit the API server pod specification file $apiserverbin on the master node and set the --authorization-mode parameter to a value that includes RBAC, for example: --authorization-mode=Node,RBAC
