[tppalani]

Hi Team,

Just want to let you know about my general query, I have EKS cluster which is running single node group with two nodes, i have used below yaml file and applied file into my cluster. When i'm seeing kube bench pod logs specifically RBAC most of the items are coming us Warning message, and remediation notes not much useful to fix recommendation method or I don't have enough knowledge to fix the issues according kube-bench logs.

Adding One points from kube-bench logs. According to this warning message, Not sure how to check secrets whether having minimal access to view k8s resources with verbs list , get, watch, create so on...

can you help me how to check secrets and how to identify whether secrets are defined as per the aqua security guidelines.
