このページでは、Google Cloud コンソールで Event Threat Detection の検出結果を確認する方法について説明します。また、Event Threat Detection の検出結果の例についても説明します。
Event Threat Detection は、組織またはプロジェクトの Cloud Logging ロギング ストリームをモニタリングし、脅威をほぼリアルタイムで検出する Security Command Center プレミアム ティアの組み込みサービスです。組織レベルで Security Command Center のプレミアム ティアを有効にすると、Event Threat Detection は組織の Google Workspace ロギング ストリームもモニタリングします。詳しくは、Event Threat Detection の概要をご覧ください。
検出結果の確認
Event Threat Detection の検出結果を表示するには、Security Command Center の [サービス] 設定でこのサービスを有効にする必要があります。Event Threat Detection を有効にした後は、Event Threat Detection が特定のログをスキャンして検出結果を生成します。Event Threat Detection がスキャンできるログの一部は、デフォルトでオフになっているため、オンにする必要がある場合があります。
Event Threat Detection が使用する組み込み検出ルールと、Event Threat Detection がスキャンするログの詳細については、次のトピックをご覧ください。
Event Threat Detection の検出結果は Security Command Center で確認できます。ログを書き込むように継続的なエクスポートを構成した場合は、Cloud Logging で検出結果を表示することもできます。Cloud Logging への継続的なエクスポートは、組織レベルで Security Command Center プレミアム ティアを有効にした場合にのみ利用できます。検出結果を生成して構成を検証するには、意図的に検出機能をトリガーし、Event Threat Detection をテストします。
Event Threat Detection の有効化は数秒で実行されます。検出のレイテンシは、ログが書き込まれてから Security Command Center で検出結果が表示されるまで通常 15 分以内です。レイテンシの詳細については、Security Command Center のレイテンシの概要をご覧ください。
Security Command Center で検出結果を確認する
Security Command Center の IAM ロールは、組織レベル、フォルダレベル、またはプロジェクト レベルで付与できます。検出結果、アセット、セキュリティ ソースを表示、編集、作成、更新する権限は、アクセス権が付与されているレベルによって異なります。Security Command Center のロールの詳細については、アクセス制御をご覧ください。
Google Cloud コンソールで検出結果を確認するには、次の操作を行います。
Google Cloud コンソールで、Security Command Center の [検出結果] ページに移動します。
必要に応じて、Google Cloud プロジェクトまたは組織を選択します。
[クイック フィルタ] セクションの [ソースの表示名] で、次のいずれかまたは両方を選択します。
- Event Threat Detection: 組み込みの Event Threat Detection 検出機能によって生成された検出結果をフィルタします。
- Event Threat Detection のカスタム モジュール: Event Threat Detection 用のカスタム モジュールによって生成された検出結果をフィルタします。
このテーブルには、Event Threat Detection の検出結果が表示されます。
特定の検出の詳細を表示するには、[
Category] の下にある検出結果の名前をクリックします。[検出の詳細] ペインが開き、次の情報が表示されます。- 問題の AI 生成のサマリープレビュー
- イベントの発生時間
- 検出結果データのソース
- 検出結果の重大度（例: 高）
- Gmail ユーザーへの Identity and Access Management（IAM）ロールの追加などの操作
- 操作を行ったユーザーが [プリンシパルのメール] の横に表示されます。
同じユーザーの操作によって発生した検出結果をすべて表示するには:
- [検出の詳細] ペインで、[プリンシパルのメール] の横にあるメールアドレスをコピーします。
- ペインを閉じます。
クエリビルダーに、次のクエリを入力します。
access.principal_email="USER_EMAIL"USER_EMAIL は、以前にコピーしたメールアドレスに置き換えます。
Security Command Center には、指定したユーザーが行った操作に関連するすべての検出結果が表示されます。
Cloud Logging での検出結果の表示
ログを書き込むように継続的エクスポートを構成すると、Cloud Logging で Event Threat Detection の検出結果を表示できます。この機能は、組織レベルで Security Command Center のプレミアム ティアを有効にした場合にのみ使用できます。
Cloud Logging で Event Threat Detection の検出結果を表示する手順は次のとおりです。
Google Cloud コンソールの [ログ エクスプローラ] に移動します。
ページの上部にあるプロジェクト セレクタで、Event Threat Detection ログを保存するプロジェクトを選択します。
[Query builder] タブをクリックします。
[リソース] プルダウン リストで、[Threat Detector] を選択します。
- すべての検出機能の検出結果を表示するには、[all detector_name] を選択します。
- 特定の検出機能の検出結果を表示するには、その名前を選択します。
[追加] をクリックします。クエリビルダーのテキスト ボックスにクエリが表示されます。
また、テキスト ボックスに次のクエリを入力します。
resource.type="threat_detector"
[クエリを実行] をクリックします。[クエリ結果] テーブルが選択したログで更新されます。
ログを表示するには、テーブル行をクリックし、[ネストされたフィールドを開く] をクリックします。
高度なログクエリを作成して、任意の数のログから一連のログエントリを指定できます。
検出結果のフォーマット例
このセクションでは、Google Cloud コンソールからエクスポートを作成したり、Security Command Center API で list メソッドを実行する場合に表示される Event Threat Detection の検出結果の JSON 出力形式について説明します。
この出力例には、検出結果で最も一般的なフィールドが含まれます。ただし、すべてのフィールドがすべての検出結果に表示されるとは限りません。実際に表示される出力は、リソースの構成と検出結果の種類と状態によって異なります。
検出結果の例を表示するには、次のノードを 1 つ以上開きます。

次のステップ
- Event Threat Detection の仕組みの詳細について確認する。
- 脅威に対する対応計画を策定して開発する方法を学習する。
