事前準備
查看建議的部署架構
這張圖表顯示部署架構中建議使用的核心元件,可收集 Microsoft Windows Sysmon 資料並傳送至 Google Security Operations。請將這項資訊與您的環境進行比對,確認已安裝這些元件。每個客戶的部署作業都會有所不同,而且可能更複雜。以下為必填項目:
- 部署架構中的系統會使用世界標準時間時區。
- Sysmon 會安裝在伺服器、端點和網域控制站上。
- 收集器 Microsoft Windows 伺服器會接收來自伺服器、端點和網域控制器的記錄。
部署架構中的 Microsoft Windows 系統使用:
- 使用來源啟動的訂閱項目,收集多部裝置上的事件。
- 用於遠端系統管理的 WinRM 服務。
在收集器 Windows 伺服器上安裝 NXLog,將記錄轉送至 Google Security Operations 轉送器。
Google 安全作業轉寄站已安裝在中央 Microsoft Windows 伺服器或 Linux 伺服器上。
