Collect ExtraHop DNS logs

This document explains how to ingest ExtraHop DNS logs to Google Security Operations using Bindplane. The parser extracts JSON-formatted logs from a raw message string, handling non-JSON data by dropping the event. Then, it maps specific fields from the extracted JSON to the corresponding fields in the Unified Data Model (UDM) schema, converting data types and handling different DNS response structures to ensure consistent representation.

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 ExtraHop DNS

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

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

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
   

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: "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_file_path: '/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 log_type: 'EXTRAHOP_DNS' raw_log_field: body ingestion_labels: service: pipelines: logs/source0__chronicle_w_labels-0: receivers: - udplog exporters: - chronicle/chronicle_w_labels

• 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 Services console or enter the following command:

  net stop BindPlaneAgent && net start BindPlaneAgent
  

Configure Syslog for ExtraHop Open Data Stream (DNS)

1. Sign in to the ExtraHop Administration using https://<extrahop-hostname-or-IP-address>/admin.

1. Go to System Configuration > Open Data Streams.
2. Click Add Target.
3. From the Target Type drop-down, select Syslog.
4. Provide the following configuration details:
   • Name: Enter a unique name to identify the target.
   • Host: Enter the Bindplane agent IP address.
   • Port: Enter the Bindplane agent port number.
   • Protocol: Select UDP, or TCP, depending on your Bindplane configuration.
   • (Optional) Select Local Time to send syslog information with timestamps in the local time zone.
   • Click Test.
5. Click Save.
