Windows - Admin task as user

Alert when admin task is initiated by regular user. Windows event id 4732 is verified towards static admin list. If the user does not belong to admin list AND the event is seen than we generate alert. Static Admin list is a logstash disctionary file that needs to be created manually. During Logstash lookup a field user.role:admin is added to an event. 4732: A member was added to a security-enabled local group
