如何建立 EventBridge 事件規則以通知有人使用我的 AWS 根使用者帳戶?

我想在有人使用我的 AWS 根使用者帳戶時收到通知。

解決方法

啟動 AWS CloudFormation 堆疊以建立 Amazon Simple Notification Service (Amazon SNS) 主題。然後,建立 Amazon EventBridge 事件規則,以從 AWS 管理主控台監控 userIdentity 根登入。

重要:在開始之前,請務必將 AWS CloudTrail 管理讀取和寫入事件設定為全部唯寫。這可讓 EventBridge 事件發起登入事件通知。如需詳細資訊,請參閱讀取和寫入事件

  2. 在美國東部 (維吉尼亞北部) 區域開啟 CloudFormation 主控台,然後選擇建立堆疊

    注意: 您必須在美國東部 (維吉尼亞北部) 區域中建立 CloudFormation 堆疊。

  3. 選擇建立堆疊,然後選擇使用新資源 (標準)

  4. 選擇上傳範本檔案下一步選擇檔案

  5. 選擇您在步驟 1 中儲存的範本,然後選擇下一步

  6. 堆疊名稱中,輸入對您有意義的名稱,例如 Root-AWS-Console-Sign-In-CloudTrail

  7. EmailAddress 中,輸入您的電郵地址,然後選擇下一步
    注意: AWS 會將確認電子郵件傳送到此電子郵件地址。

  8. 選項中選擇下一步,然後選擇建立

  9. 檢查您的電子郵件收件匣是否有 AWS 確認電子郵件,然後選擇確認訂閱確認 SNS 訂閱請求。您將收到**訂閱已確認!**訊息。

  10. 若要測試通知,請登出 AWS 管理主控台。然後,使用您的 AWS 根使用者帳戶登入 AWS 管理主控台

  11. 檢查您的電子郵件收件匣是否有 AWS 通知訊息。記下包含登入事件詳細資訊的 CloudTrail 記錄 userIdentitysourceIPAddressMFAUsed

如果您不想收到通知,請刪除您在步驟 2 中建立的 CloudFormation 堆疊
