   Tiller, found in Helm v2, has known security challenges. It requires administrative privileges and acts as a shared resource accessible to any authenticated user. Tiller can lead to privilege escalation as restricted users can impact other users. It is recommend to use Helm v3+ which does not contain Tiller for these reasons. This policy validates that there is not an image containing the name `tiller`.
