如果您在驗證 GPO 和 WMI 消費者後仍未看到「攻擊指標」警示，可以檢閱 Tenable Identity Exposure 的內部記錄檔。

  • 檢查 CETI 記錄中是否有下列錯誤訊息：

[2022-02-22 22:23:27:570 UTC WARNING] Some domain controllers are not generating IOA events: 'CORP-DC'. {SourceContext="DirectoryEventToCetiAdObjectMessageMapper", DirectoryId=2, Dns="corp.bank.com", Host="10.10.20.10", Source=SYSVOL, Version="3.11.5"}

  • 如果您看到此訊息，請驗證 GPO 設定和 WMI 消費者是否在上述錯誤訊息中所列的網域控制器 (DC) 上執行。

  • 如果您看到與下列類似的錯誤：「Tenable Identity Exposure 需要稽核原則...」，請檢查您現有的 GPO，確保您沒有將所需的稽核原則設定為「無稽核」。

  • 如果您收到指出「RSOP...」的錯誤：

  • 檢查稽核原則並檢視 Sysvol 資料夾中的記錄檔，瞭解您在安裝期間是否遇到過任何問題。

Cygni 會記錄攻擊，並列出 Tenable Identity Exposure 為產生警示而呼叫的特定 .gz 檔案。
