 ### Set severity threshold
 Only evaluate policies with a severity equal to or higher than a threshold.
 ```
 ./rbac-police eval lib/ -s High

 ### Discover protections
 Improve accuracy by considering features gates and admission controllers that can protect against certain attacks. Note that [NodeRestriction](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#noderestriction) is identified by impersonating a node and *dry-run creating a pod*, which may be logged by some systems.

 Note that by default, `rbac-police` only looks into service accounts assigned to a pod. Use `-a` to include all service accounts.
