Event Threat Detection の使用

このページでは、Security Command Center のダッシュボードで 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 の検出例についても説明します。

Event Threat Detection は、組織の Cloud Logging と Google Workspace 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。詳細は、Event Threat Detection の概要をご覧ください。

次の動画は、Event Threat Detection の設定手順と、ダッシュボードの使用方法を示しています。Event Threat Detection の検出結果の表示と管理の詳細については、このページの検出結果の確認をご覧ください。

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 を有効にして、組織、フォルダ、プロジェクトでログを有効にすると、Event Threat Detection によって検出結果が生成されます。Event Threat Detection の検出結果のタイプの詳細については、ルールをご覧ください。

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。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 レベルで付与されます。検出結果、アセット、セキュリティ ソース、セキュリティ マークを、表示、編集、作成、更新する権限は、アクセス権が付与され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。

Security Command Center で Event Threat Detection の検出結果を確認するには、次の操作を行います。

  1. Google Cloud Console で Security Command Center の [検出] ページに移動します。

    [検出] に移動

  2. [表示] の横にある [ソースタイプ] をクリックします。

  3. [ソースタイプ] リストで、[Event Threat Detection] を選択します。

  4. 特定の検出の詳細を表示するには、[カテゴリ] 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] パネルが開き、次の情報が表示されます。

    • イベントの内容
    • 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:
    • 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(properties_principalEmail の横に表示)
  5. 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:

    1. [検出の詳細] ペインで、properties_principalEmail の横にあるメールアドレスをコピーします。
    2. [検出の詳細] ペインを閉じます。
    3. [検出] タブの [フィルタ] ボックスに「sourceProperties.properties_principalEmail:USER_EMAIL」と入力します。ここで、USER_EMAIL は以前にコピーしたメールアドレスです。

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

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。

  1. Cloud Console で [ログ エクスプローラ] に移動します。

    [ログ エクスプローラ] に移動

  2. 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。

  3. [Query builder] タブをクリックします。

  4. [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。
  5. [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。

  6. 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"
    

  7. [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。

  8. 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。

Chronicle で検出結果を調査する

Chronicle を使用すると、Malware: Bad DomainMalware: Bad IPPersistence: IAM Anomalous GrantBrute Force: SSHExfiltration: BigQuery Data Exfiltration の検出結果を調査できます。

Event Threat Detection は Chronicle とシームレスに統合されます。脅威を調査して、統合されたタイムラインで関連するアクションやイベントをピボット分析できます。Chronicle は、検出結果の質を高め、関心のある指標を特定し、調査を簡素化します。

たとえば、Event Threat Detection は、不審な IAM ロールの付与を行ったプリンシパルを特定した場合、Chronicle を使用して、ユーザーの最近のログイン アクティビティを表示し、ロールの付与後に他の不審な変更が行われたかどうかを確認できます。

サポートされている Event Threat Detection の検出結果を Chronicle に送信する手順は次のとおりです。

  1. Google Cloud Console で Security Command Center の [検出] ページに移動します。

    [検出] に移動

  2. [表示] の横にある [ソースタイプ] をクリックします。

  3. [ソースタイプ] リストで、[Event Threat Detection] を選択します。

    テーブルに、選択したソースタイプの検出結果が表示されます。

  4. テーブルの [カテゴリ] で、検出結果の Malware: Bad DomainMalware: Bad IPPersistence: IAM Anomalous GrantBrute Force: SSH、または Exfiltration: BigQuery Data Exfiltration をクリックします。

  5. [検出の詳細] ペインで、[Chronicle で調査] をクリックします。

  6. Chronicle のガイド付きユーザー インターフェースの手順に沿って操作します。

Chronicle の使用方法については、Chronicle のドキュメントをご覧ください。このドキュメントには、調査の実施に役立つガイドが含まれています。

検出結果の詳細を確認して、脅威を調査することもできます。詳細については、脅威の調査と対応をご覧ください。

検出フォーマットの例

このセクションでは、Security Command Center ダッシュボードからエクスポートを作成する場合や 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。

出力例には、すべての検出結果に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。
