Google Chrome のログを収集する

以下でサポートされています。

このドキュメントでは、Chrome Enterprise レポート コネクタを設定して Chrome ブラウザと ChromeOS のセキュリティ イベント ログを収集する方法と、ログフィールドが Chrome 統合データモデル（UDM）フィールドにマッピングされる方法について説明します。

詳細については、Google SecOps へのデータの取り込みをご覧ください。

概要

一般的なデプロイは、Google SecOps にログを送信するように構成された Chrome ブラウザと ChromeOS セキュリティ イベントで構成されています。お客様のデプロイはそれぞれ異なり、より複雑になる場合もあります。 このパイプラインは以下のコンポーネントで構成されます。

  • Chrome: 収集する Chrome ブラウザと ChromeOS のセキュリティ イベント。

  • Chrome Enterprise レポート コネクタ: Chrome Enterprise レポート コネクタは、Chrome ログを Google SecOps に転送します。

  • Google SecOps: Chrome ログを保持、分析します。

取り込みラベルによって、未加工のログデータを構造化 UDM 形式に正規化するパーサーが識別されます。このドキュメントの情報は、取り込みラベル CHROME_MANAGEMENT が付加されたパーサーに適用されます。

始める前に

  • Google Workspace 管理者アカウントがあることを確認します。

  • デプロイ アーキテクチャ内のすべてのシステムが、UTC タイムゾーンに構成されていることを確認します。

  • Chronicle Ingestion API キーがあることを確認します。キーがない場合は、Google SecOps サポートまたは Google SecOps のお客様の担当者に連絡して Chronicle Ingestion API キーをリクエストしてください。

  • 詳しくは、Chrome のログイベントをご覧ください。

Chrome ブラウザ クラウド管理を設定する

Chrome ブラウザ クラウド管理を設定する大まかな手順は次のとおりです。

次のステップを実行して、Chrome ブラウザ クラウド管理を設定します。

  1. 管理コンソールで、[メニュー] > [デバイス] > [Chrome] > [管理対象ブラウザ] をクリックします。

  2. 省略可: 最上位の組織を選択するか、トークンを生成する組織部門を選択して、ブラウザをその特定の組織部門に直接登録します。詳細については、組織部門の追加をご覧ください。

  3. [登録] をクリックします。 ブラウザを初めて登録する場合、Chrome ブラウザ クラウド管理（CBCM）の利用規約に同意するよう求められます。

  4. [登録トークンをクリップボードにコピー] をクリックします。

  5. クラウド管理型の Chrome ブラウザを登録するには、[完了] をクリックします。

  6. 管理コンソールで、[メニュー] > [デバイス] > [Chrome] > [設定] > [ユーザーとブラウザ] に移動します。すべての子組織にポリシーが継承されるよう、最上位の組織部門を選択します。[ブラウザに関するレポート] までスクロールします。

  7. [管理対象ブラウザに関するレポート] を [管理対象ブラウザのクラウド レポートを有効にする] に設定します。

  8. Chrome ブラウザのレポートを有効にするには、[保存] をクリックします。

  9. 管理コンソールで、[メニュー] > [デバイス] > [Chrome] > [コネクタ] に移動します。

  10. （省略可）Chrome Enterprise Connectors の設定を初めて行う場合は、画面の指示に沿って Chrome Enterprise Connectors を有効にします。

  11. 画面上部の [+ 新しいプロバイダの設定] をクリックします。

  12. 右側に表示されるパネルで、Google SecOps の設定を見つけて [設定] をクリックします。

  13. 構成 ID、API キー、ホスト名を入力します。

    • 構成 ID: [ユーザーとブラウザの設定] ページと [コネクタ] ページに表示される ID。

    • API キー: Chronicle ingestion API を呼び出してお客様を識別するときに指定する API キー。

    • ホスト名: 取り込み API エンドポイント。米国のお客様の場合、これは常に malachiteingestion-pa.googleapis.com になります。他のリージョンについては、リージョン エンドポイントのドキュメントをご覧ください。

  14. [構成を追加] をクリックして、新しいプロバイダ構成を追加します。
