Esse analisador usa padrões grok para extrair campos de mensagens syslog do Apple macOS e preenche o Modelo de dados unificado (UDM) com os valores extraídos, incluindo o carimbo de data/hora, o nome do host, o host intermediário, a linha de comando, o ID do processo e a descrição. O analisador categoriza o evento como STATUS_UPDATE se um nome de host estiver presente. Caso contrário, ele atribui a categoria GENERIC_EVENT ao evento. Por fim, o analisador enriquece o evento da UDM com informações do fornecedor e do produto.
Antes de começar
Verifique se você tem uma instância do Google Security Operations.
Confira se você tem acesso root ao host do Auditd.
Verifique se você instalou o rsyslog no host do Auditd.
Verifique se você tem um host Windows 2012 SP2 ou mais recente ou Linux com systemd.
Se você estiver executando por trás de um proxy, verifique se as portas do firewall estão abertas.

Instalar o agente do BindPlane
Para instalação no Windows, execute o seguinte script: msiexec /i "https://github.com/observIQ/bindplane-agent/releases/latest/download/observiq-otel-collector.msi" /quiet.
Para instalação no Linux, execute o seguinte script: sudo sh -c "$(curl -fsSlL https://github.com/observiq/bindplane-agent/releases/latest/download/install_unix.sh)" install_unix.sh.
Configurar o agente do Bindplane para ingerir Syslog e enviar ao Google SecOps
Acesse a máquina em que o agente do Bindplane está instalado.
Edite o arquivo config.yaml da seguinte forma:
receivers:
tcplog:
# Replace the below port <54525> and IP <0.0.0.0> with your specific values
listen_address: "0.0.0.0:54525"
exporters:
chronicle/chronicle_w_labels:
compression: gzip
# Adjust the creds location below according the placement of the credentials file you downloaded
creds: '{ json file for creds }'
# Replace <customer_id> below with your actual ID that you copied
customer_id: <customer_id>
endpoint: malachiteingestion-pa.googleapis.com
# You can apply ingestion labels below as preferred
ingestion_labels:
log_type: SYSLOG
namespace: auditd
raw_log_field: body
service:
pipelines:
logs/source0__chronicle_w_labels-0:
receivers:
- tcplog
exporters:
- chronicle/chronicle_w_labels
Reinicie o agente do Bindplane para aplicar as mudanças usando o seguinte comando:
sudo systemctl bindplane restart
Exportar Syslog do macOS
Instale o syslog-ng usando o Homebrew:
brewinstallsyslog-ng
Configure o syslog-ng:
Edite o arquivo syslog-ng.conf (geralmente localizado em /usr/local/etc/syslog-ng/syslog-ng.conf):
sudovi/usr/local/etc/syslog-ng/syslog-ng.conf
Adicione o seguinte bloco de configuração.
Dependendo da configuração do Bindplane, você pode mudar o método de entrega para tcp ou deixar como udp.
Substitua <BindPlaneAgent_IP> e <BindPlaneAgent_Port> pelo endereço IP e pela porta reais do seu agente do Bindplane:
Verifique o status de syslog-ng. Ele deve estar listado como iniciado:syslog-ng

A linha de comando do processo é extraída do campo data usando um padrão grok.
dados
read_only_udm.principal.process.pid
O ID do processo é extraído do campo data usando um padrão grok.
dados
read_only_udm.metadata.event_timestamp
O carimbo de data/hora do evento é extraído do campo data usando um padrão grok e convertido em um objeto de carimbo de data/hora. Fixado no código como "MacOS" no analisador. Fixado no código como "Apple" no analisador. Definido como "STATUS_UPDATE" se um nome do host for extraído dos registros. Caso contrário, defina como "GENERIC_EVENT".
log_type
read_only_udm.metadata.log_type
Mapeado diretamente do campo log_type do registro bruto.

Pre-GA features might have limited support, and changes to pre-GA features might not be compatible with other pre-GA versions. For more information, see the [Google SecOps Technical Support Service guidelines](https://chronicle.security/legal/technical-support-services-guidelines/) and the [Google SecOps Service Specific Terms](https://chronicle.security/legal/service-terms/).\n\nThis parser uses grok patterns to extract fields from Apple macOS syslog messages and populates the Unified Data Model (UDM) with the extracted values, including the timestamp, hostname, intermediary host, command line, process ID, and description. The parser categorizes the event as `STATUS_UPDATE` if a hostname is present; otherwise, it assigns the category `GENERIC_EVENT` to the event. Finally, the parser enriches the UDM event with vendor and product information.\n\nBefore you begin\n----------------\n\n- Ensure that you have a Google Security Operations instance.\n- Ensure that you have root access to the Auditd host.\n- Ensure that you installed rsyslog on the Auditd host.\n- Ensure that you have a Windows 2012 SP2 or later or Linux host with systemd.\n- If running behind a proxy, ensure firewall [ports](/chronicle/docs/ingestion/use-bindplane-agent#verify_the_firewall_configuration) are open.\n\nGet Google SecOps ingestion authentication file\n-----------------------------------------------\n\n1.
