Raccogliere i dati DNS di Microsoft Windows

Supportato in:

Google SecOps SIEM

Questo documento:

• Descrive l'architettura di deployment e i passaggi di installazione, oltre a qualsiasi configurazione richiesta che produca log supportati dal parser di Google Security Operations per gli eventi DNS 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.

In base all'architettura di deployment, configura l'agente BindPlane o l'agente NXLog per importare i log DNS di Windows in Google Security Operations. Ti consigliamo di utilizzare BindPlane Agent per inoltrare i log DNS di Windows a Google Security Operations.

Le informazioni in questo documento si applicano al parser con l'etichetta di importazione WINDOWS_DNS. L'etichetta di importazione identifica l'analizzatore sintattico che normalizza i dati dei log non elaborati in formato UDM strutturato.

Prima di iniziare

Prima di configurare BindPlane Agent o l'agente NXLog, completa le seguenti attività:

• Attiva la registrazione diagnostica DNS sul server DNS di Windows.
• Configura tutti i sistemi con il fuso orario UTC.
• Esaminare i dispositivi e le versioni supportati
• Esaminare i tipi di log supportati

Esamina i dispositivi e le versioni supportati

Il parser di Google Security Operations supporta i log delle seguenti versioni di Microsoft Windows Server. Microsoft Windows Server viene rilasciato con le seguenti versioni: Foundation, Essentials, Standard e Datacenter. Lo schema di eventi dei log gerado da ogni versione non è diverso.

• Microsoft Windows Server 2019
• Microsoft Windows Server 2016

• Microsoft Windows Server 2012 R2

  Il parser di Google Security Operations supporta i log raccolti da NXLog Enterprise Edition.

Esamina i tipi di log supportati

Il parser di Google Security Operations supporta i seguenti tipi di log generati dai server DNS di Microsoft Windows. Per ulteriori informazioni su questi tipi di log, consulta la documentazione su logging e diagnostica DNS. L'analizzatore supporta i log generati con testo in lingua inglese e non è supportato con i log generati in lingue diverse dall'inglese.

• Log di controllo: per una descrizione di questo tipo di log, vedi Eventi di controllo.
• Log di Analytics: per una descrizione di questo tipo di log, consulta Eventi di Analytics.
• Configura i server DNS Microsoft Windows. Per ulteriori informazioni, consulta Installare e attivare i log di diagnostica DNS.

Configurare l'agente BindPlane

Ti consigliamo di utilizzare BindPlane Agent per inoltrare i log DNS di Windows a Google SecOps.

1. Installa l'agente BindPlane su ogni server DNS Windows. Per ulteriori informazioni sull'installazione di BindPlane Agent, consulta le istruzioni di installazione di BindPlane Agent.

2. Crea un file di configurazione per l'agente BindPlane con i seguenti contenuti.

   receivers:
     windowseventlog/dns_log:
     channel: Microsoft-Windows-DNSServer/Audit
     raw: true
   processors:
     batch:
   
   exporters:
     chronicle/dns_log:
       endpoint: https://malachiteingestion-pa.googleapis.com
       creds: '{
       "type": "service_account",
       "project_id": "malachite-projectname",
       "private_key_id": `PRIVATE_KEY_ID`,
       "private_key": `PRIVATE_KEY`,
       "client_email":"`SERVICE_ACCOUNT_NAME`@malachite-`PROJECT_ID`.`SERVICE_ACCOUNT_DOMAIN`",
       "client_id": `CLIENT_ID`,

       "universe_domain": "googleapis.com"
       }'
     log_type: 'WINDOWS_DNS'
     override_log_type: false
     raw_log_field: body
     customer_id: `CUSTOMER_ID`
   
   service:
     pipelines:

         receivers:
           - windowseventlog/dns_log
         processors: [batch]
         exporters: [chronicle/dns_log]
   

3. Sostituisci PRIVATE_KEY_ID, PRIVATE_KEY SERVICSERVICE_ACCOUNT_NAME,PROJECT_ID, CLIENT_ID, SERVICE_ACCOUNT_DOMAIN e CUSTOMER_ID con i rispettivi valori del file JSON dell'account di servizio che puoi scaricare dalla Google Cloud Platform. Per ulteriori informazioni sulle chiavi degli account di servizio, consulta la documentazione su come creare ed eliminare le chiavi degli account di servizio.

4. Per avviare il servizio dell'agente observerIQ, seleziona Servizi > Estensioni > il servizio observerIQ > Avvia.

Configura NXLog e il forwarder di Google Security Operations

Il seguente diagramma mostra un'architettura in cui sono installati agenti NXLog per raccogliere e inviare eventi DNS di Microsoft Windows a Google SecOps. Confronta queste informazioni con il tuo ambiente per assicurarti che questi componenti siano installati. Il tuo deployment potrebbe essere diverso da questa rappresentazione.

Se utilizzi l'agente NXLog anziché BindPlane Agent, completa i seguenti prerequisiti: - Installa NXLog sui server Microsoft Windows cluster per raccogliere e inoltrare i log al server Microsoft Windows o Linux centrale. - Installa il forwarder Google SecOps sul server Microsoft Windows o Linux centrale.

1. Installa NXLog su ogni server DNS Microsoft Windows. Segui la documentazione di NXLog.

2. Crea un file di configurazione per ogni istanza NXLog. Utilizza il modulo di input im_etw per estrarre i log di analisi DNS e il modulo di input im_msvistalog per gli audit log.

   • Per ulteriori informazioni sul modulo di input im_etw, consulta Event Tracing for Microsoft Windows (im_etw), incluse informazioni su configurazione di NXLog per il DNS di Microsoft Windows.
   • Per ulteriori informazioni sul modulo di input im_msvistalog, consulta Log eventi per Microsoft Windows 2008/Vista e versioni successive (im_msvistalog).

   Ecco un esempio di configurazione di NXLog. Sostituisci i valori <hostname> e <port> con le informazioni sul server centralizzato Microsoft Windows o Linux. Per convertire e analizzare facoltativamente i log in JSON anziché in XML, modifica la riga Exec to_xml(); in Exec to_json();. Per ulteriori informazioni, consulta la documentazione di NXLog relativa al modulo om_tcp.

3. Installa il forwarder di Google Security Operations sul server Microsoft Windows o Linux centrale. Per informazioni sull'installazione e sulla configurazione del forwarder, consulta Installazione e configurazione del forwarder su Linux o Installazione e configurazione del forwarder su Microsoft Windows.

4. Configura il forwarder di Google Security Operations per inviare i log a Google Security Operations. Ecco un esempio di configurazione del forwarder.

     - syslog:
         common:
           enabled: true
           data_type: WINDOWS_DNS

Deprecato:

I seguenti campi labels per i nomi UDM sono deprecati: about.labels, intermediary.labels, observer.labels, principal.labels, src.labels, security_result.about.labels e target.labels. Per i parser esistenti, oltre a questi campi UDM, i campi dei log vengono mappati anche ai campi UDM additional.fields chiave/valore. Per i nuovi analizzatori, vengono utilizzate le impostazioni chiave/valore nei campi UDM additional.fields anziché i campi UDM labels ritirati. Ti consigliamo di aggiornare le regole esistenti per utilizzare le impostazioni chiave/valore nei campi UDM additional.fields anziché nei campi UDM labels ritirati.

Log di debug legacy

Deprecato:

I seguenti campi labels per i nomi UDM sono deprecati: about.labels, intermediary.labels, observer.labels, principal.labels, src.labels, security_result.about.labels e target.labels. Per i parser esistenti, oltre a questi campi UDM, i campi dei log vengono mappati anche ai campi UDM additional.fields chiave/valore. Per i nuovi analizzatori, vengono utilizzate le impostazioni chiave/valore nei campi UDM additional.fields anziché i campi UDM labels ritirati. Ti consigliamo di aggiornare le regole esistenti per utilizzare le impostazioni chiave/valore nei campi UDM additional.fields anziché nei campi UDM labels ritirati.

Riferimento alla mappatura dei campi: ID evento al tipo di evento UDM

Questa sezione descrive in che modo il parser mappa gli ID evento agli event_types UDM. In generale, gli eventi vengono mappati a metadata.event_type di NETWORK_DNS, tranne per gli ID evento nella sezione seguente.

Nota: i valori % (ad es. %1, %2, %3, %{EventID}) sono segnaposto variabili.
