Recolha registos do Google Chrome

Compatível com:

Este documento descreve como pode recolher registos de eventos de segurança do navegador Chrome e do ChromeOS configurando um conetor de relatórios do Chrome Enterprise e como os campos de registo são mapeados para os campos do modelo de dados unificado (UDM) do Chrome.

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

Vista geral

Uma implementação típica consiste em eventos de segurança do navegador Chrome e do ChromeOS configurados para enviar registos para o Google SecOps. Cada implementação do cliente pode ser diferente e mais complexa. A implementação consiste nos seguintes componentes:

  • Chrome: os eventos de segurança do navegador Chrome e do ChromeOS que quer recolher.

  • Conetor de relatórios do Chrome Enterprise: o conetor de relatórios do Chrome Enterprise encaminha os registos do Chrome para o Google SecOps.

  • Google SecOps: retém e analisa os registos do Chrome.

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 CHROME_MANAGEMENT.

Antes de começar

  • Certifique-se de que tem uma conta de administrador do Google Workspace.

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

  • Certifique-se de que tem uma chave da API Chronicle Ingestion. Se não tiver uma, contacte o apoio técnico do Google SecOps ou o seu ponto de contacto do cliente do Google SecOps para pedir a chave da API de carregamento do Chronicle.

  • Para mais informações, consulte os eventos de registo do Chrome.

Configure o Chrome Browser Cloud Management

Seguem-se os passos de nível elevado para configurar o Chrome Browser Cloud Management:

Execute os seguintes passos para configurar o Chrome Browser Cloud Management.

  1. Na consola do administrador, clique em Menu > Dispositivos > Chrome > Navegadores geridos.

  2. Opcional: selecione a organização de nível superior ou a unidade organizacional onde quer gerar um token que inscreva navegadores diretamente nessa unidade organizacional específica. Para mais informações, consulte o artigo Adicione uma unidade organizacional.

  3. Clique em Inscrever-se. Se esta for a sua primeira inscrição no navegador, é-lhe pedido que aceite os Termos de Utilização do Chrome Browser Cloud Management (CBCM).

  4. Clique em Copiar símbolo de inscrição para a área de transferência.

  5. Para inscrever navegadores Chrome geridos na nuvem, clique em Concluído.

  6. Na consola do administrador, aceda a Menu > Dispositivos > Chrome > Definições > Utilizadores e navegadores. Selecione a sua unidade organizacional de nível superior para que todas as organizações secundárias herdem a política. Desloque a página para baixo até Relatórios do navegador.

  7. Defina Relatórios do navegador gerido como Ativar relatórios da nuvem do navegador gerido.

  8. Para ativar os relatórios do navegador Chrome, clique em Guardar.

  9. Na consola do administrador, aceda a Menu > Dispositivos > Chrome > Conetores.

  10. Opcional: se estiver a configurar as definições do Chrome Enterprise Connectors pela primeira vez, siga as instruções para ativar o Chrome Enterprise Connectors.

  11. Na parte superior, clique em + Configuração de novo fornecedor.

  12. No painel apresentado à direita, encontre a configuração do Google SecOps e clique em Configurar.

  13. Introduza o ID de configuração, a chave da API e o nome do anfitrião:

    • ID de configuração: o ID apresentado na página Definições do utilizador e do navegador e na página Conetores.

    • Chave da API: a chave da API a especificar quando chama a API de carregamento do Chronicle para identificar o cliente.

    • Nome do anfitrião: o ponto final da API de carregamento. Para os clientes dos EUA, este valor é sempre malachiteingestion-pa.googleapis.com; para outras regiões, consulte a documentação de pontos finais regionais.

  14. Clique em ADICIONAR CONFIGURAÇÃO para adicionar a nova configuração do fornecedor.
