Ce document décrit un type de résultat de détection de menace dans Security Command Center. Ces résultats sont générés par les détecteurs de menaces lorsqu'ils détectent une menace potentielle dans vos ressources cloud. Pour obtenir la liste complète des résultats de détection de menace disponibles, consultez cet index.
Event Threat Detection examine les journaux d'audit pour détecter la suppression d'hôtes exécutant des applications protégées par le service Backup and DR. Une fois un hôte supprimé, les applications qui y sont associées ne peuvent pas être sauvegardées.
Le plan de réponse suivant peut être adapté à ce résultat, mais il peut également avoir un impact sur vos opérations.
Veillez à bien évaluer les informations que vous collectez dans votre enquête pour déterminer quelle est la meilleure réponse à apporter aux problèmes soulevés par les résultats.
Voici un exemple de fichier JSON de résultat.
