Collect Imperva Data Risk Analytics (DRA) 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 Imperva Data Risk Analytics (DRA) logs to Google Security Operations using Bindplane. The parser extracts fields from the Data Risk Analytics syslog formatted logs. It uses grok and kv to parse the log message and then maps these values to the Unified Data Model (UDM). Imperva DRA helps uncover suspicious data activity and prioritize critical incidents among billions of audit events.

Before you begin

Make sure you have the following prerequisites:

• A Google SecOps instance
• Windows 2016 or later, or a Linux host with systemd
• If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
• Privileged access to the Imperva DRA management console

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
   

Additional installation resources

• For additional installation options, consult this installation guide.

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_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: 'IMPERVA_DRA'
       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 forwarding on Imperva DRA

1. Sign in to the Imperva DRA Management Console.
2. Go to Configuration > SIEM Integration.
3. In the Syslog Server section, provide the following configuration details:
   • Server IP: Enter the BindPlane Agent IP address.
   • Port: Enter the BindPlane Agent port number (default 514).
   • Protocol: Select UDP or TCP, depending on your BindPlane Agent configuration.
   • Facility: Select appropriate syslog facility (for example, LOCAL0).
4. Click Send Test Syslog Message to verify connectivity.
5. In the Events to be sent section, configure:
   • Event Classes: Select Breach Detection and/or Risk Reduction based on requirements.
   • Notification Types: Choose incident open/close/reopen actions and their severity levels.
   • Message Format: Select JSON for structured data format or Raw for basic syslog format.
6. Configure Severity Threshold to determine which severity levels should be forwarded.
7. Save the configuration.

Note: It is recommended not to send Issues notifications to SIEM systems due to their dynamic nature. Use only incident notifications for consistent SIEM integration.
