How to: Dynamic Admission Control
To prevent invalid Prometheus alerting and recording rules from causing failures in a deployed Prometheus instance,
an [admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/)
is provided to validate `PrometheusRule` resources upon initial creation or update.

For more information on this feature, see the [user guide](https://prometheus-operator.dev/docs/platform/webhook/).
