    Collect Palo Alto Prisma SD-WAN logs

    Supported in:

    This document explains how to ingest Palo Alto Prisma SD-WAN (formerly Cloudgenix SD-WAN) logs to Google Security Operations using Bindplane. The parser extracts fields from the syslog and flow logs, mapping them to the Unified Data Model (UDM). It handles both structured and unstructured syslog messages, performing key-value parsing and Grok matching to extract relevant information like source/destination IPs, hostnames, event types, and security details, and populates UDM fields accordingly. The parser also processes flow logs, extracting network information and mapping it to the UDM's network, principal, target, intermediary, and security result schemas.

    Before you begin

    Make sure you have the following prerequisites:

    • Google SecOps instance
    • Windows 2016 or later or a Linux host with systemd
    • If running behind a proxy, ensure firewall ports are open
    • Privileged access to the Palo Alto Prisma SD-WAN (formerly Cloudgenix SD-WAN)

    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. Save the file securely on the system where Bindplane 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 the 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"

    Additional installation resources

    For additional installation options, consult the installation guide .

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

    1. Access the configuration file:
      • Locate the config.yaml file. Typically, it's in the /etc/bindplane-agent/ directory on Linux or in the installation directory on Windows.
      • Open the file using a text editor (for example, nano , vi , or Notepad).

    2. Edit the config.yaml file as follows:

        ``` 
 yaml 
 receivers 
 : 
  
 udplog 
 : 
  
 # Replace the port and IP address as required 
  
 listen_address 
 :

 # Adjust the path to the credentials file you downloaded in Step 1

 # Replace with your actual customer ID from Step 2

 ```
      • Replace the port and IP address as required in your infrastructure.
      • Replace <customer_id> with the actual customer ID.
      • Update /path/to/ingestion-authentication-file.json to the path where the authentication file was saved in the Get Google SecOps ingestion authentication file section.

    Restart the Bindplane agent to apply the changes

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

       sudo  
systemctl  
restart  
bindplane-agent

    • To restart the Bindplane agent in Windows, you can either use the Servicesconsole or enter the following command:

       net stop BindPlaneAgent && net start BindPlaneAgent

    Configure Prisma SD-WAN Syslog Profile

    1. Sign in to the Prisma SD-WAN.
    2. Go to Manage > Resources > Configuration Profiles.
    3. Select Syslog.
    4. Click Create Syslog Profile.
    5. Provide the following configuration details:
      • Name: Enter a name for this profile.
      • Select the Enable Flow Loggingcheckbox.
      • Severity: Select the Severity Level from a severity level of Critical, Major, or Minor.
      • Protocol: Select the protocol type as UDP, or TCP, depending on your Bindplane agent configuration.
      • Select the Server IPradio button.
