Sensitive Actions Service の使用

このページでは、Google Cloud コンソールで Sensitive Actions Service の検出結果を確認する方法について説明します。また、Sensitive Actions Service の検出結果の例についても説明します。

Sensitive Actions Service は Security Command Center の組み込みサービスです。このサービスは、Google Cloud の組織、フォルダ、プロジェクトで悪意をもって行われた場合にビジネスに損害を与える可能性のあるアクションを検出します。詳細については、Sensitive Actions Service の概要をご覧ください。

Sensitive Actions Service の検出結果を確認する

Security Command Center のスタンダード ティアを有効にしていれば、Sensitive Actions Service は常に有効になっています。無効にすることはできません。Sensitive Actions Service の検出タイプの詳細については、検出結果をご覧ください。

Sensitive Actions Service は、機密性が高いとみなされるアクションを検出すると、検出結果とログエントリを作成します。検出結果は Google Cloud コンソールで確認できます。Cloud Logging でログエントリをクエリできます。Sensitive Actions Service をテストするには、機密性の高いアクションを実行して、Google Cloud コンソールの [検出結果] ページに検出結果が表示されることを確認します。詳細については、Sensitive Actions Service のテストをご覧ください。

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 Sensitive Actions Service の検出結果を確認するには、次の手順に従います。

  1. 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。

    [検出結果] に移動

  2. 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。

    プロジェクト セレクタ

  3. [クイック フィルタ] セクションの [ソースの表示名] サブセクションで、[Sensitive Actions Service] を選択します。

    Sensitive Actions Service の検出結果がテーブルに入力されます。

  4. 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:
    • 組織レベルでオーナーや編集者のロールを Gmail ユーザーに追加するなどのアクション。
    • アクション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。
  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、[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。
    2. ペインを閉じます。
    3. 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

Sensitive Actions Service は、検出した機密性の高いアクションごとにログエントリを Google Cloud Platform ログに書き込みます。Security Command Center を有効にしていない場合でも、これらのログエントリは書き込まれます。

Cloud Logging で機密性の高いアクションのログエントリを表示するには、次の操作を行います。

  1. Google Cloud コンソールの [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. ページ上部にあるプロジェクト セレクタで、Sensitive Actions Service のログエントリを確認するプロジェクトを選択します。組織レベルのログエントリを表示するには、組織を選択します。

  3. [クエリ] テキスト ボックスに、リソース定義「resource.type="sensitiveaction.googleapis.com/Location"」を入力します。

  4. [RUN QUERY] をクリックします。クエリ結果テーブルが更新され、クエリ期間内に書き込まれた一致するログエントリが表示されます。

  5. ログエントリの詳細を表示するには、テーブルの行をクリックして、[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 Sensitive Actions Service の検出結果の JSON 出力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。
