Microsoft Windows Sysmon-Daten erfassen

In diesem Dokument wird Folgendes beschrieben:

  • beschreibt die Bereitstellungsarchitektur und Installationsschritte sowie alle erforderlichen Konfigurationen, die Logs generieren, die vom Chronicle Parser für Microsoft Windows Sysmon-Ereignisse unterstützt werden. Eine Übersicht über die Datenaufnahme in Chronicle finden Sie unter Datenaufnahme in Chronicle.
  • enthält Informationen dazu, wie der Parser Felder im ursprünglichen Log den Chronicle Unified Data Model-Feldern zuordnet.

Die Informationen in diesem Dokument gelten für den Parser mit dem Aufnahmelabel WINDOWS_SYSMON. Das Aufnahmelabel gibt an, welcher Parser Log-Rohdaten in das strukturierte UDM-Format normalisiert.

Hinweise

Dieses Diagramm zeigt die empfohlenen Kernkomponenten in einer Bereitstellungsarchitektur zum Erfassen und Senden von Microsoft Windows Sysmon-Daten an Chronicle. Vergleichen Sie diese Informationen mit Ihrer Umgebung, damit die Komponenten installiert sind. Jede Kundenbereitstellung unterscheidet sich von dieser Darstellung und kann komplexer sein. Folgendes ist erforderlich:

  • Systeme in der Bereitstellungsarchitektur werden mit der UTC-Zeitzone konfiguriert.
  • Sysmon wird auf Servern, Endpunkten und Domaincontrollern installiert.
  • Der Microsoft Windows-Collector-Server empfängt Protokolle von Servern, Endpunkten und Domaincontrollern.
  • Microsoft Windows-Systeme in der Bereitstellungsarchitektur verwenden Folgendes:

    • Von der Quelle initiierte Abos, um Ereignisse auf mehreren Geräten zu erfassen.
    • WinRM-Dienst für die Remote-Systemverwaltung
  • NXLog wird auf dem Collector-Fensterserver installiert, um Logs an den Chronicle-Forwarder weiterzuleiten.

  • Der Chronicle-Forwarder wird auf einem zentralen Microsoft Windows- oder Linux-Server installiert.

    Bereitstellungsarchitektur

Unterstützte Geräte und Versionen ansehen

Der Chronicle-Parser unterstützt Logs, die von den folgenden Microsoft Windows-Serverversionen generiert wurden. Microsoft Windows Server wird in den folgenden Versionen veröffentlicht: Foundation, Essentials, Standard und Datacenter. Das Ereignisschema von Logs, die von den einzelnen Versionen generiert werden, unterscheidet sich nicht.

  • Microsoft Windows Server 2019
  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2012

Der Chronicle-Parser unterstützt Logs, die generiert werden von:

  • Clientsysteme mit Microsoft Windows 7 und höher
  • Sysmon Version 13.24.

Der Chronicle-Parser unterstützt Logs, die von der NXLog Community oder Enterprise Edition erfasst wurden.

Unterstützte Logtypen prüfen

Der Chronicle-Parser unterstützt die folgenden Logtypen, die von Microsoft Windows Sysmon generiert werden. Weitere Informationen zu diesen Logtypen finden Sie in der Microsoft Windows Sysmon-Dokumentation. Es unterstützt Logs, die mit englischsprachigem Text generiert wurden. Logs, die in einer anderen Sprache als Englisch generiert wurden, werden nicht unterstützt.

Protokolltyp Beschreibung
Sysmon-Protokolle Der Sysmon-Kanal enthält 27 Ereignis-IDs. (Ereignis-ID: 1 bis 26 und 255).
Eine Beschreibung dieses Logtyps finden Sie in der Dokumentation zu Microsoft Windows Sysmon-Ereignissen.

Microsoft Windows-Server, -Endpunkte und -Domaincontroller konfigurieren

  1. Server, Endpunkte und Domaincontroller installieren und konfigurieren Weitere Informationen finden Sie in der Dokumentation zur Microsoft Windows Sysmon-Konfiguration.
  2. Richten Sie einen Collector Microsoft Windows Server ein, um die erfassten Logs aus mehreren Systemen zu parsen.
  3. Zentralen Microsoft Windows- oder Linux-Server einrichten
  4. Konfigurieren Sie alle Systeme mit der UTC-Zeitzone.
  5. Konfigurieren Sie die Geräte so, dass Protokolle an den Collector Microsoft Windows-Server weitergeleitet werden.

NXLog- und Chronicle-Forwarder konfigurieren

  1. Installieren Sie NXLog auf dem Collector Microsoft Windows-Server. Folgen Sie der NXLog-Dokumentation, einschließlich Informationen zum Konfigurieren von NXLog zum Erfassen von Logs von Sysmon.
  2. Erstellen Sie eine Konfigurationsdatei für NXLog. Verwenden Sie das Eingabemodul im_msvistalog. Hier ist ein Beispiel für eine NXLog-Konfiguration. Ersetzen Sie die Werte <hostname> und <port> durch Informationen zum zentralen Microsoft Windows- oder Linux-Zielserver. Weitere Informationen finden Sie in der NXLog-Dokumentation zum Modul om_tcp.

    define ROOT     C:\Program Files (x86)\nxlog
    define SYSMON_OUTPUT_DESTINATION_ADDRESS <hostname>

        Exec        $EventTime = integer($EventTime) / 1000;
        Exec        $EventReceivedTime = integer($EventReceivedTime) / 1000;
        Exec        to_json();
    </Output>
    
    <Route r2>
        Path    windows_sysmon_eventlog => out_chronicle_sysmon

  3. Installieren Sie den Chronicle-Forwarder auf dem zentralen Microsoft Windows- oder Linux-Server. Informationen zum Installieren und Konfigurieren des Forwarders unter Linuxfinden Sie unter Linux installieren und konfigurieren oder unter Installation und Konfiguration des Forwarders unter Microsoft Windows.

  4. Konfigurieren Sie den Chronicle-Forwarder so, dass Logs an Chronicle gesendet werden. Hier ist ein Beispiel für eine Forwarder-Konfiguration.

      - syslog:
          common:
            enabled: true
            data_type: WINDOWS_SYSMON
            Data_hint:
