Goal

Detect when an unauthenticated request user is permitted in Kubernetes.

Strategy

This rule monitors when any action is permitted (@http.status_code:[100 TO 299]) for an unauthenticated user (@user.username:\"system:anonymous\"). The /livez and /readyz endpoints are commonly accessed unauthenticated and are excluded in the query filter.

Triage and response

Inspect all of the HTTP paths accessed and determine if any of the path should be permitted by unauthenticated users.
Determine what IP addresses accessed Kubernetes endpoints which may contain sensitive data.

Changelog
