Kubernetes Pod Created in Kube Namespace
Set up the kubernetes integration.
Goal
Detect when a user is creating a pod in one of the Kubernetes default namespaces.
Strategy
This rule monitors when a create (@http.method:create) action occurs for a pod (@objectRef.resource:pods) within either of the kube-system or kube-public namespaces.
The only users creating pods in the kube-system namespace should be cluster administrators. Furthermore, it is best practice to not run any cluster critical infrastructure in the kube-system namespace.
The kube-public namespace is intended for Kubernetes objects which should be readable by unauthenticated users. Thus, a pod should likely not be created in the kube-public namespace.
Triage and response
Determine if the user should be creating this new pod in one of the default namespaces.
