Collect Arbor Edge Defense logs

Supported in:

This document explains how to collect the Netscout (Arbor Edge Defense) logs to Google Security Operations using a Bindplane agent. The parser first extracts fields from raw syslog messages using a grok pattern matching specific vendor-defined formats. Then, it maps the extracted fields and their values to corresponding attributes within the Google SecOps UDM schema, enabling standardized representation and analysis of security events.

Before you begin

  • Ensure that you have a Google SecOps instance.
  • Ensure that you are using Windows 2016 or later, or a Linux host with systemd.
  • If running behind a proxy, ensure firewall ports are open.
  • Ensure that you have privileged access to Netscout.

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 ID from the Organization Details section.

Install the Bindplane agent

Windows installation

  1. Open the 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

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

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

  1. Access the configuration file:

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

  2. Edit the config.yaml file as follows:

    receivers:
    udplog:
        # Replace the port and IP address as required
        listen_address: "0.0.0.0:514"

exporters:
    chronicle/chronicle_w_labels:
        compression: gzip
        # Adjust the path to the credentials file you downloaded in Step 1
        creds: '/path/to/ingestion-authentication-file.json'
        # Replace with your actual customer ID from Step 2
        customer_id: <customer_id>
        endpoint: malachiteingestion-pa.googleapis.com
        # Add optional ingestion labels for better organization
        ingestion_labels:
            log_type: ARBOR_EDGE_DEFENSE
            raw_log_field: body

service:
    pipelines:
        logs/source0__chronicle_w_labels-0:
            receivers:
                - udplog
            exporters:
                - chronicle/chronicle_w_labels

  3. Replace the port and IP address as required in your infrastructure.

  4. Replace <customer_id> with the actual customer ID.

  5. 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 Services console or enter the following command:

    net stop BindPlaneAgent && net start BindPlaneAgent

Configure Syslog export on Netscout (Arbor Edge Defense)

  1. Sign in to the Netscout web UI.
  2. Select Administration > Notification > Groups.
  3. In the Notification group window, click Add notification group.
  4. Provide the following configuration details:
    • Destination: enter Bindplane agent IP address.
    • Port: enter the Bindplane agent port number.
    • Facility: select facility Local0.
    • Severity: select Informational.
  5. Click Save.
  6. Go to Administration > Configuration Management > Commit, or select Config Commit.
