Recoger registros de proxy web de Zscaler

Disponible en:

En este documento se describe cómo puede exportar registros de Zscaler Webproxy configurando un feed de Google Security Operations y cómo se asignan los campos de registro a los campos del modelo de datos unificado (UDM) de Google SecOps.

Para obtener más información, consulta el artículo Descripción general de la ingesta de datos en Google SecOps.

Una implementación típica consta de Zscaler Webproxy y el feed de webhook de Google SecOps configurado para enviar registros a Google SecOps. Cada implementación de cliente puede ser diferente y más compleja.

La implementación contiene los siguientes componentes:

  • Proxy web de Zscaler: la plataforma desde la que recoges los registros.

  • Feed de Google SecOps: el feed de Google SecOps que obtiene registros de Zscaler Webproxy y escribe registros en Google SecOps.

  • Google SecOps: conserva y analiza los registros.

Una etiqueta de ingestión identifica el analizador que normaliza los datos de registro sin procesar en formato UDM estructurado. La información de este documento se aplica al analizador con la etiqueta de ingestión ZSCALER_WEBPROXY.

Antes de empezar

Asegúrate de que cumples los siguientes requisitos previos:

  • Acceso a la consola de Zscaler Internet Access. Para obtener más información, consulta la ayuda de ZIA sobre acceso seguro a Internet y SaaS.
  • Zscaler Webproxy 2024 o posterior
  • Todos los sistemas de la arquitectura de implementación están configurados con la zona horaria UTC.
  • La clave de API necesaria para completar la configuración de la fuente en Google Security Operations. Para obtener más información, consulta Configurar claves de API.

Configurar feeds

Hay dos puntos de entrada diferentes para configurar feeds en la plataforma Google SecOps:

  • Configuración de SIEM > Feeds
  • Centro de contenido > Paquetes de contenido

Configurar feeds desde Configuración de SIEM > Feeds

Para configurar varios feeds de distintos tipos de registro en esta familia de productos, consulte Configurar feeds por producto.

Para configurar un solo feed, sigue estos pasos:

  1. Ve a Configuración de SIEM > Feeds.
  2. Haz clic en Añadir feed.
  3. En la página siguiente, haga clic en Configurar un solo feed.
  4. En el campo Nombre del feed, introduce un nombre para el feed; por ejemplo, Registros de proxy web de Zscaler.
  5. Selecciona Webhook como Tipo de fuente.
  6. Seleccione Zscaler como Tipo de registro.
  7. Haz clic en Siguiente.
  8. Opcional: Introduce los valores de los siguientes parámetros de entrada:
    1. Delimitador de división: delimitador que se usa para separar las líneas de registro. Déjelo en blanco si no se usa ningún delimitador.
    2. Espacio de nombres de recursos: el espacio de nombres de recursos.
    3. Etiquetas de ingestión: etiqueta que se aplicará a los eventos de este feed.
  9. Haz clic en Siguiente.
  10. Revise la nueva configuración de la feed y haga clic en Enviar.
  11. Haga clic en Generar clave secreta para generar una clave secreta que autentique este feed.

Configurar feeds desde el Centro de contenido

Especifique los valores de los siguientes campos:

  • Delimitador de división: el delimitador que se usa para separar las líneas de registro, como \n.

Opciones avanzadas

  • Nombre del feed: valor rellenado automáticamente que identifica el feed.
  • Tipo de fuente: método usado para recoger registros en Google SecOps.
  • Espacio de nombres de recursos: el espacio de nombres de recursos.
  • Etiquetas de ingestión: la etiqueta aplicada a los eventos de este feed.
  • Haz clic en Siguiente.
  • Revise la configuración del feed en la pantalla Finalizar y, a continuación, haga clic en Enviar.
  • Haz clic en Generar clave secreta para generar una clave secreta que autentique este feed.

Configurar Zscaler Webproxy

  1. En la consola de Zscaler Internet Access, haga clic en Administración > Servicio de streaming de Nanolog > Feeds de NSS en la nube y, a continuación, en Añadir feed de NSS en la nube.
  2. Aparecerá la ventana Añadir feed de NSS de Cloud. En la ventana Add Cloud NSS Feed (Añadir feed de NSS de Cloud), introduce los detalles.
  3. Escribe un nombre para el feed en el campo Nombre del feed.
  4. Selecciona NSS para web en Tipo de NSS.
  5. Seleccione el estado en la lista Estado para activar o desactivar el feed de NSS.
  6. En el menú desplegable Tasa de SIEM, deja el valor Ilimitado. Para suprimir el flujo de salida debido a licencias u otras restricciones, cambia el valor.
  7. Seleccione Otro en la lista Tipo de SIEM.
  8. Selecciona Inhabilitado en la lista Autenticación de OAuth 2.0.
  9. Introduce un límite de tamaño para la carga útil de una solicitud HTTP individual según la práctica recomendada del SIEM en Tamaño máximo del lote. Por ejemplo, 512 KB.
  10. Introduce la URL HTTPS del endpoint de la API de Chronicle en el campo URL de la API con el siguiente formato:

      https://<CHRONICLE_REGION>-chronicle.googleapis.com/v1alpha/projects/<GOOGLE_PROJECT_NUMBER>/locations/<LOCATION>/instances/<CUSTOMER_ID>/feeds/<FEED_ID>:importPushLogs
    
    • CHRONICLE_REGION: región en la que se aloja tu instancia de Chronicle. Por ejemplo, "US".
    • GOOGLE_PROJECT_NUMBER: número de proyecto de BYOP. Obtén este valor de C4.
    • LOCATION: región de Chronicle. Por ejemplo, "US".
    • CUSTOMER_ID: ID de cliente de Chronicle. Obtenido de C4.
    • FEED_ID: ID de feed que se muestra en la interfaz de usuario del feed cuando se crea un webhook
    • URL de API de ejemplo:
    https://us-chronicle.googleapis.com/v1alpha/projects/12345678910/locations/US/instances/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/feeds/yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy:importPushLogs
    
  11. Haga clic en Añadir encabezado HTTP y, a continuación, añada encabezados HTTP con el siguiente formato:

    • Header 1: Clave1: X-goog-api-key y Valor1: clave de API generada en las credenciales de API de Google Cloud BYOP.
    • Header 2: Clave2: X-Webhook-Access-Key y Valor2: clave secreta de la API generada en "CLAVE SECRETA" del webhook.
  12. Seleccione Registros web en la lista Tipos de registro.

  13. Seleccione JSON en la lista Tipo de salida del feed.

  14. Asigna el valor , \ " a Carácter de escape del feed.

  15. Para añadir un campo al Formato de salida del feed,seleccione Personalizado en la lista Tipo de salida del feed.

  16. Copia y pega el Formato de salida del feed y añade campos nuevos. Asegúrate de que los nombres de las claves coincidan con los nombres de los campos.

  17. A continuación, se muestra el formato de salida de la feed predeterminado:

      \{ "sourcetype" : "zscalernss-web", "event" : \{"datetime":"%d{yy}-%02d{mth}-%02d{dd} %02d{hh}:%02d{mm}:%02d{ss}","reason":"%s{reason}","event_id":"%d{recordid}","protocol":"%s{proto}","action":"%s{action}","transactionsize":"%d{totalsize}","responsesize":"%d{respsize}","requestsize":"%d{reqsize}","urlcategory":"%s{urlcat}","serverip":"%s{sip}","requestmethod":"%s{reqmethod}","refererURL":"%s{ereferer}","useragent":"%s{eua}","product":"NSS","location":"%s{elocation}","ClientIP":"%s{cip}","status":"%s{respcode}","user":"%s{elogin}","url":"%s{eurl}","vendor":"Zscaler","hostname":"%s{ehost}","clientpublicIP":"%s{cintip}","threatcategory":"%s{malwarecat}","threatname":"%s{threatname}","filetype":"%s{filetype}","appname":"%s{appname}","pagerisk":"%d{riskscore}","threatseverity":"%s{threatseverity}","department":"%s{edepartment}","urlsupercategory":"%s{urlsupercat}","appclass":"%s{appclass}","dlpengine":"%s{dlpeng}","urlclass":"%s{urlclass}","threatclass":"%s{malwareclass}","dlpdictionaries":"%s{dlpdict}","fileclass":"%s{fileclass}","bwthrottle":"%s{bwthrottle}","contenttype":"%s{contenttype}","unscannabletype":"%s{unscannabletype}","deviceowner":"%s{deviceowner}","devicehostname":"%s{devicehostname}","keyprotectiontype":"%s{keyprotectiontype}"\}\}
