Collect Juniper Junos logs

Supported in:

Google secops SIEM

Note: This feature is covered by Pre-GA Offerings Terms of the Google Security Operations Service Specific Terms. 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 and the Google SecOps Service Specific Terms.

This document explains how to ingest Juniper Junos logs to Google Security Operations using Bindplane.

Juniper Junos OS is the operating system that powers Juniper Networks routers, switches, and security devices. It provides a unified platform for network infrastructure management, routing, switching, and security functions with comprehensive logging of system events, security events, and network traffic. The parser extracts fields from Juniper Junos syslog and key-value formatted logs. It uses grok and/or kv to parse the log message and then maps these values to the Unified Data Model (UDM). It also sets default metadata values for the event source and type.

Before you begin

Make sure you have the following prerequisites:

• A Google SecOps instance
• Windows Server 2016 or later, or Linux host with systemd
• If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
• Privileged access to the Juniper device running Junos OS

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.

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 Bindplane agent installation guide.

Configure Bindplane agent to ingest syslog and send to Google SecOps

Locate the configuration file

      udplog:
          listen_address: "0.0.0.0:514"
  
  exporters:
      chronicle/chronicle_w_labels:
          compression: gzip
          creds_file_path: '/path/to/ingestion-authentication-file.json'
          customer_id: 'YOUR_CUSTOMER_ID'
          endpoint: malachiteingestion-pa.googleapis.com
          log_type: 'JUNIPER_JUNOS'
          raw_log_field: body
          ingestion_labels:
  
  service:
      pipelines:
          logs/source0__chronicle_w_labels-0:
              receivers:
                  - udplog
              exporters:
                  - chronicle/chronicle_w_labels
  

Configuration parameters

• Replace the following placeholders:

    • 0.0.0.0: IP address to listen on (0.0.0.0 to listen on all interfaces)
    • 514: Port number to listen on (standard syslog port)

  • 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
    • YOUR_CUSTOMER_ID: Customer ID from the Get customer ID section
    • 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
    • log_type: Log type exactly as it appears in Chronicle (JUNIPER_JUNOS)

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 Syslog forwarding on Juniper Junos

1. Connect to the Juniper device via SSH or console.

2. Enter configuration mode:

   configure
   

3. Configure the syslog host with the following commands:

   set system syslog host BINDPLANE_IP port 514
   set system syslog host BINDPLANE_IP facility-override local7
   set system syslog host BINDPLANE_IP log-prefix JUNOS
   

   • Replace BINDPLANE_IP with the IP address of the Bindplane agent host.

4. Configure additional log sources (optional but recommended):

   set system syslog host BINDPLANE_IP authorization info
   set system syslog host BINDPLANE_IP daemon info
   set system syslog host BINDPLANE_IP kernel info
