Notification personnalisée pour les règles de configuration

Il peut arriver que des règles de configuration critiques non conformes nécessitent une sensibilisation accrue directement auprès de votre équipe InfoSec et de votre équipe de direction. Pour de tels scénarios, AMS vous recommande de configurer une notification personnalisée basée sur un événement de non-conformité.

Exemples :
