Collect Imperva FlexProtect logs

This document explains how to ingest Imperva FlexProtect logs to Google Security Operations using Bindplane. The parser first cleans up and pre-processes incoming logs, then attempts to extract Common Event Format (CEF) data. Depending on the presence of specific fields like "src" and "sip", it assigns a UDM event type and maps relevant CEF fields to the UDM schema, finally enriching the output with additional custom fields. Imperva FlexProtect provides flexible deployment of Imperva security solutions (SecureSphere, Cloud WAF, Bot Protection) across hybrid cloud environments.

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 FlexProtect management console or individual product consoles

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_FLEXPROTECT'
       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 FlexProtect

For SecureSphere Component (On-premises/Cloud)

1. Sign in to the Imperva SecureSphere Management Console.
2. Go to Configuration > Action Sets.
3. Click Add to create a new Action Set.

4. Click Add Action and provide the following configuration details:

   • Name: Enter a descriptive name (for example, Google SecOps Syslog).
   • Action Type: Select Syslog.
   • Host: Enter the Bindplane agent IP address.
   • Port: Enter the Bindplane agent port number (default 514).
   • Protocol: Select UDP or TCP.
   • Syslog Log Level: Select DEBUG.
   • Syslog Facility: Select LOCAL0.
   • Format: Select CEF (Common Event Format).

5. Save the action configuration and apply it to relevant security policies.

For Cloud WAF/Incapsula Component

1. Sign in to the Imperva Cloud Console.
2. Go to Logs > Log Setup.
3. Configure syslog destination:
   • Host: Enter the Bindplane agent IP address.
   • Port: Enter the Bindplane agent port number (default 514).
   • Protocol: Select UDP or TCP.
   • Format: Select CEF.
