description = """
This rule detects attempts to create resources in Kubernetes clusters that are forbidden by the authorization policy. It
specifically looks for creation requests that are denied with a "forbid" decision, indicating that the user or service
account does not have the necessary permissions to perform the action. This activity is commonly associated with
adversaries attempting to create resources in a Kubernetes environment without proper authorization, which can lead to
unauthorized access, manipulation of cluster resources, lateral movement and/or privilege escalation.
