Rulename	XbowMediumFindings
Description	Creates an incident for each Medium severity finding reported by XBOW that is currently in an open state. These findings represent moderate security risks that should be addressed in a timely manner. Each alert is deduplicated per finding so re-ingestion of the same finding does not produce duplicate incidents.
