Les API sous la version /beta dans Microsoft Graph sont susceptibles d’être modifiées. L’utilisation de ces API dans des applications de production n’est pas prise en charge. Pour déterminer si une API est disponible dans v1.0, utilisez le sélecteur Version .

Obtenez la liste des règles de détection personnalisées. Avec les détections personnalisées, vous pouvez surveiller de manière proactive différents événements et états système et y répondre, notamment les activités de violation présumée et les ressources mal configurées dans leur réseau d’organisation. Les règles de détection personnalisées, écrites en langage de requête Kusto (KQL), déclenchent automatiquement des alertes et des actions de réponse dès que des événements correspondent à leurs requêtes KQL.

Cette API est disponible dans les déploiements de cloud national suivants.
