Raccogliere i dati DHCP di Microsoft Windows
Questo documento:
- Descrive l'architettura di implementazione e i passaggi di installazione, oltre a qualsiasi configurazione richiesta che generi log supportati dal parser Google Security Operations per gli eventi DHCP di Microsoft Windows. Per una panoramica dell'importazione dati in Google Security Operations, consulta Importazione dei dati in Google Security Operations.
- Include informazioni su come l'analizzatore sintattico mappa i campi nel log originale ai campi del modello di dati unificato di Google Security Operations.
Le informazioni in questo documento si applicano al parser con l'etichetta di importazione WINDOWS_DHCP. L'etichetta di importazione identifica l'analizzatore sintattico che normalizza i dati dei log non elaborati in formato UDM strutturato.
Prima di iniziare
Esamina l'architettura di deployment consigliata
Questo diagramma mostra i componenti di base consigliati in un'architettura di deployment per raccogliere e inviare eventi DHCP di Microsoft Windows a Google Security Operations. Confronta queste informazioni con il tuo ambiente per assicurarti che questi componenti siano installati. Ogni implementazione del cliente sarà diversa da questa rappresentazione e potrebbe essere più complessa. Sono richiesti i seguenti requisiti:
- Server Microsoft Windows con il ruolo di server DHCP.
- Tutti i sistemi configurati con il fuso orario UTC.
- NXLog è installato su server Microsoft Windows in cluster per raccogliere e inoltrare i log per i canali di notifiche di operazioni, amministrazione e filtro.
Il forwarder di Google Security Operations è installato sul server Microsoft Windows o Linux centrale.
Esamina le versioni e i dispositivi supportati
Il parser di Google Security Operations supporta i log generati dalle seguenti versioni e protocolli di Microsoft Windows Server. Microsoft Windows Server viene rilasciato nelle seguenti versioni: Foundation, Essentials, Standard e Datacenter. Lo schema degli eventi dei log generati da ogni versione non è diverso.
Versione del server | Protocollo supportato |
---|---|
Microsoft Windows Server 2019 | DHCPv4 |
Microsoft Windows Server 2016 | DHCPv4 |
Microsoft Windows Server 2012 | DHCPv4 |
Il parser di Google Security Operations supporta i log raccolti da NXLog Enterprise Edition o Community Edition.
Esamina i tipi di log supportati
Il parser di Google Security Operations supporta i seguenti tipi di log generati dai server DHCP di Microsoft Windows. Per ulteriori informazioni su questi tipi di log, consulta la documentazione di Microsoft Windows DHCP Server. Supporta i log generati con testo in lingua inglese e non è supportato con i log generati in lingue diverse dall'inglese.
Tipo | Formato dei dati | Descrizione |
---|---|---|
Audit logging | CSV | Sono incluse le attività di avvio e arresto e di locazione. |
Eventi operativi | Formato evento Microsoft Windows | Fornisce il logging della configurazione DHCP. |
Eventi amministratore | Formato evento Microsoft Windows | Fornisce la registrazione degli eventi amministrativi del server DHCP. |
Filtrare gli eventi di notifica | Formato evento Microsoft Windows | Fornisce il logging degli eventi di filtro basato sul livello di collegamento del server DHCP. |
Configurare l'agente BindPlane
Raccogli i log DHCP di Windows utilizzando l'agente BindPlane.
Dopo l'installazione, il servizio BindPlane Agent viene visualizzato come servizio observerIQ
nell'elenco dei servizi Windows.
Installa e configura i server DHCP Windows. Per ulteriori informazioni sull'installazione dei server DHCP di Windows, consulta la Panoramica del protocollo DHCP (Dynamic Host Configuration Protocol).
Installa l'agente BindPlane nel collector in esecuzione su un server Windows. Per ulteriori informazioni sull'installazione di BindPlane Agent, consulta le istruzioni di installazione di BindPlane Agent.
Crea un file di configurazione per l'agente BindPlane con i seguenti contenuti.

Configurare il server DHCP Microsoft Windows
- Installa e configura i server DHCP Microsoft Windows. Per informazioni, consulta la documentazione di Microsoft Windows.
- Configura i sistemi con il fuso orario UTC.
- Installa NXLog su ogni server DHCP Microsoft Windows. Segui la documentazione di NXLog, incluse le informazioni sulla configurazione di NXLog per DHCP di Microsoft Windows.
Crea un file di configurazione per ogni istanza NXLog. Utilizza i moduli im_file e im_msvistalog.
Per informazioni sull'utilizzo del modulo di input im_file, consulta Configurazione con la console di gestione DHCP.
Per informazioni sull'utilizzo del modulo im_msvistalog, consulta Log eventi per Microsoft Windows 2008/Vista e versioni successive (im_msvistalog).
Ecco un esempio di configurazione di NXLog. Segui queste indicazioni sulla raccolta dei log da Microsoft Windows a 64 bit utilizzando un agente NXLog a 32 bit.
Sostituisci i valori

e<port>
con le informazioni sul server Microsoft Windows centrale di destinazione. Per ulteriori informazioni, consulta la documentazione di NXLog sul modulo om_tcp.Modifica il percorso del file di log nella sezione <Input audit_logs_csv> della proprietà File alla posizione del file contenente i log di controllo DHCP. Consulta la documentazione di NXLog relativa al modulo di input im_file.
