Recolha registos de eventos de abuso do Google Cloud

Compatível com:

Google secops SIEM

Este documento descreve como pode recolher registos de eventos de abuso do Google Cloud ativando o Google Cloud carregamento de telemetria para o Google SecOps e como os campos de registo dos registos de eventos de abuso do Google Cloud são mapeados para os campos do modelo de dados unificado (UDM) do Google SecOps.

Para mais informações, consulte o artigo Ingestão de dados no Google Security Operations.

A implementação contém os seguintes componentes:

Google Cloud: os Google Cloud serviços e produtos a partir dos quais recolhe registos.
Registos de eventos de abuso do Google Cloud: os registos de eventos de abuso do Google Cloud que estão ativados para carregamento para o Google SecOps.
Google SecOps: o Google SecOps retém e analisa os registos de eventos de abuso do Google Cloud.

Uma etiqueta de carregamento identifica o analisador que normaliza os dados de registo não processados para o formato UDM estruturado. As informações neste documento aplicam-se ao analisador com a etiqueta de carregamento GCP_ABUSE_EVENTS.

Antes de começar

Certifique-se de que todos os sistemas na arquitetura de implementação estão configurados no fuso horário UTC.

Configure Google Cloud para carregar registos de eventos de abuso do Google Cloud

Para carregar registos de eventos de abuso do Google Cloud para o Google SecOps, siga os passos descritos no artigo Carregue Google Cloud registos para o Google SecOps.

Uma implementação típica consiste em registos de eventos de abuso do Google Cloud ativados para carregamento no Google SecOps. Cada implementação do cliente pode diferir desta representação e pode ser mais complexa.

Se tiver problemas ao carregar registos de eventos de abuso do Google Cloud, contacte o apoio técnico do Google SecOps.

Formato de registo e exemplo de eventos de abuso do Google Cloud suportados

O analisador de eventos de abuso do Google Cloud suporta registos no formato JSON. Segue-se um exemplo:
