    Collect Barracuda WAF logs

    Supported in:

    This document explains how to ingest Barracuda Web Application Firewall (WAF) logs to Google Security Operations using the Bindplane agent.

    Barracuda WAF generates logs for web traffic (TR) and web firewall events (WF) in JSON and syslog formats. The parser normalizes fields and maps them to the Unified Data Model (UDM), handling IP address resolution, directionality mapping, and severity normalization.

    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 Barracuda WAF
    • If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
    • Privileged access to the Barracuda WAF

    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 the Bindplane agent will be installed.

    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 IDfrom the Organization Detailssection.

    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 Promptor PowerShellas 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).

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

    Locate the configuration file

    • Linux:

       sudo  
nano  
/etc/bindplane-agent/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

    Configuration parameters

    Replace the following placeholders:

    • Receiver configuration:

      • listen_address : IP address and port to listen on:
        • 0.0.0.0 to listen on all interfaces (recommended)
        • Port 514 is the standard syslog port (requires root on Linux; use 1514 for non-root)

    • 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 copied from the Google SecOps console
      • endpoint : Regional endpoint URL:
        • US: malachiteingestion-pa.googleapis.com
        • Europe: europe-malachiteingestion-pa.googleapis.com
        • Asia: asia-southeast1-malachiteingestion-pa.googleapis.com
