インシデントをリストする
名前空間: microsoft.graph.security
重要
Microsoft Graph の /beta バージョンの API は変更される可能性があります。 実稼働アプリケーションでこれらの API を使用することは、サポートされていません。 v1.0 で API を使用できるかどうかを確認するには、Version セレクターを使用します。
Organizationでの攻撃を追跡するために Microsoft 365 Defender によって作成されたインシデント オブジェクトの一覧を取得します。
攻撃は通常、デバイス、ユーザー、メールボックスなど、さまざまな種類のエンティティに対して発生し、複数の アラート オブジェクトが発生します。 Microsoft 365 Defender は、同じ攻撃手法または同じ攻撃者とアラートをインシデントに関連付 けます。
この操作を使用すると、インシデントをフィルター処理して並べ替えて、情報に基づいたサイバー セキュリティ対応を作成できます。 環境保持ポリシーで指定した時間範囲内で、ネットワーク上でフラグが設定されたインシデントのコレクションを公開します。 最新のインシデントが一覧の上部に表示されます。
この API は、次の国内クラウド展開で使用できます。
| グローバル サービス | 米国政府機関 L4 | 米国政府機関 L5 (DOD) | 21Vianet が運営する中国 |
