Importante

Las API de la versión /beta de Microsoft Graph están sujetas a cambios. No se admite el uso de estas API en aplicaciones de producción. Para determinar si una API está disponible en la versión 1.0, use el selector de Versión.

Obtenga una lista de reglas de detección personalizadas. Con las detecciones personalizadas, puede supervisar y responder de forma proactiva a diversos eventos y estados del sistema, incluida la actividad de infracción sospechosa y los recursos mal configurados en la red de su organización. Las reglas de detección personalizadas, que se escriben en el lenguaje de consulta Kusto (KQL), desencadenan automáticamente alertas y acciones de respuesta una vez que haya eventos que coincidan con sus consultas de KQL.

Esta API está disponible en las siguientes implementaciones nacionales de nube.
