Collect Preempt logs

Supported in:

Google secops SIEM

This document explains how to ingest Preempt logs to Google Security Operations using the Bindplane agent.

Preempt Security is an identity threat detection and response platform that generates security alerts for Active Directory threats, including anomalous authentication behavior, privilege escalation, and lateral movement. It exports logs in CEF (Common Event Format) format via syslog.

Note: Preempt Security was acquired by CrowdStrike in September 2020 and has been fully integrated into CrowdStrike Falcon Identity Protection. The standalone Preempt product is no longer available. If you have migrated to CrowdStrike Falcon Identity Protection, see the Collect CrowdStrike Falcon logs guide instead.

Before you begin

Make sure you have the following prerequisites:

• A Google SecOps instance
• Windows Server 2016 or later, or Linux host with systemd
• Network connectivity between the Bindplane agent and the Preempt server
• If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
• Privileged access to the Preempt management console with administrator permissions

Get Google SecOps ingestion authentication file

1. Sign in to the Google SecOps console.
2. Go to SIEM Settings > Collection Agents.
3. Download the Ingestion Authentication File.

4. Save the file securely on the system where Bindplane will be installed.

   Note: This JSON file contains credentials for authenticating the Bindplane agent to Google SecOps.

Get Google SecOps customer ID

1. Sign in to the Google SecOps console.
2. Go to SIEM Settings > Profile.

3. Copy and save the Customer ID from the Organization Details section.

   Note: The customer ID is required for configuring the Bindplane agent exporter.

Install the Bindplane agent

Install the Bindplane agent on your Windows or Linux operating system according to the following instructions.

Windows installation

1. Open Command Prompt or PowerShell as an administrator.

2. Run the following command:

   msiexec /i "https://github.com/observIQ/bindplane-agent/releases/latest/download/observiq-otel-collector.msi" /quiet
   

3. Wait for the installation to complete.

4. Verify the installation by running:

   sc query observiq-otel-collector
   

   The service should show as RUNNING.

Linux installation

1. Open a terminal with root or sudo privileges.

2. Run the following command:

   sudo sh -c "$(curl -fsSlL https://github.com/observiq/bindplane-agent/releases/latest/download/install_unix.sh)" install_unix.sh
   

3. Wait for the installation to complete.

4. Verify the installation by running:

   sudo systemctl status observiq-otel-collector
   

   The service should show as active (running).

Additional installation resources

For additional installation options and troubleshooting, see the Bindplane agent installation guide.

Configure the Bindplane agent to ingest syslog and send to Google SecOps

Locate the configuration file

• Linux:

  sudo nano /opt/observiq-otel-collector/config.yaml
  

• Windows:

  notepad "C:\Program Files\observIQ OpenTelemetry Collector\config.yaml"
  

Edit the configuration file

• Replace the entire contents of config.yaml with the following configuration:

  receivers:
      tcplog:
          listen_address: "0.0.0.0:514"
  
  exporters:
      chronicle/preempt:
          compression: gzip
          creds_file_path: '<CREDS_FILE_PATH>'
          customer_id: '<CUSTOMER_ID>'
          endpoint: <REGION_ENDPOINT>
          log_type: PREEMPT
          raw_log_field: body
          ingestion_labels:
              env: production
  
  service:
      pipelines:
          logs/preempt_to_chronicle:
              receivers:
                  - tcplog
              exporters:
                  - chronicle/preempt
  

Configuration parameters

Replace the following placeholders:

• Receiver configuration:

  • tcplog: Receives syslog over TCP. Use udplog if your Preempt deployment forwards over UDP.
  • 0.0.0.0:514: Listens on all interfaces on port 514. Change the port if needed (for example, 1514 for non-root Linux).

• Exporter configuration:

  • <CREDS_FILE_PATH>: Full path to ingestion authentication file:
    • Linux: /etc/bindplane-agent/ingestion-auth.json
    • Windows: C:\Program Files\observIQ OpenTelemetry Collector\ingestion-auth.json
  • <CUSTOMER_ID>: Customer ID from the Get Google SecOps customer ID step.
  • <REGION_ENDPOINT>: Regional endpoint URL:
    • US: malachiteingestion-pa.googleapis.com
    • Europe: europe-malachiteingestion-pa.googleapis.com
    • Asia: asia-southeast1-malachiteingestion-pa.googleapis.com
    • See Regional Endpoints for complete list.

Save the configuration file

• After editing, save the file:
  • Linux: Press Ctrl+O, then Enter, then Ctrl+X
  • Windows: Click File > Save

Restart the Bindplane agent to apply the changes

• To restart the Bindplane agent in Linux, run the following command:

  sudo systemctl restart observiq-otel-collector
  

  1. Verify the service is running:

     sudo systemctl status observiq-otel-collector
     

  2. Check logs for errors:

     sudo journalctl -u observiq-otel-collector -f
     

• To restart the Bindplane agent in Windows, choose one of the following options:

  • Command Prompt or PowerShell as administrator:

    net stop observiq-otel-collector && net start observiq-otel-collector
    

  • Services console:

    1. Press Win+R, type services.msc, and press Enter.
    2. Locate observIQ OpenTelemetry Collector.
    3. Right-click and select Restart.

    4. Verify the service is running:

       sc query observiq-otel-collector
       

    5. Check logs for errors:

       type "C:\Program Files\observIQ OpenTelemetry Collector\log\collector.log"
       

Configure Preempt syslog forwarding

Note: Preempt Security is a deprecated product. These instructions apply to legacy Preempt deployments only. If you have migrated to CrowdStrike Falcon Identity Protection, use the CrowdStrike integration guide instead.

1. Sign in to the Preempt management console.
2. Navigate to Settings > SIEM Integration.
3. Enable syslog forwarding.
4. Provide the following configuration details:
   • Protocol: Select TCP (must match the Bindplane agent receiver configuration).
   • Format: Select CEF.
   • Syslog server address: Enter the IP address of the Bindplane agent host (for example, 192.168.1.100).
   • Port: Enter 514 (must match the Bindplane agent receiver port).
5. Select the event types to forward:
   • Alerts
   • Policy violations
   • Anomalous authentication events
6. Click Save or Apply.
7. Verify that logs are being sent by checking the Bindplane agent logs.
