Answer» Use the correct auth mode with API server authorization-mode=Node,RBAC Ensure all traffic is protected by TLS Use API authentication (smaller cluster may use CERTIFICATES but LARGER multi-tenants may want an AD or some OIDC authentication). Make kubeless protect its API via authorization-mode=Webhook. Make sure the kube-dashboard uses a restrictive RBAC role policy Monitor RBAC failures Remove default ServiceAccount permissions Filter egress to Cloud API metadata APIs Filter out all traffic coming into kube-system namespace EXCEPT DNS. A default deny policy on all inbound on all NAMESPACES is good practice. You explicitly allow PER deployment.Use a podsecurity policy to have container restrictions and protect the Node Keep kube at the latest version.
