Overview

Customers using QRadar SIEM can leverage a native integration that initiates native ingestion API alerts from Security Edition Zero Trust alerts. Customers can augment the capabilities of QRadar SIEM with threat intelligence and Cyber Storage capabilities of Superna Security Edition.

Solution Overview

Superna Defender Zero Trust API receives webhook alerts and parses the key data into a syslog UDP or TCP event that is sent to QRadar. QRadar SIEM is a modular architecture that provides real-time visibility of your IT infrastructure, which you can use for threat detection and prioritization.

Advanced Zero Trust Capabilities

• Webhook to native syslog alarm integration

What Is QRadar SIEM?

Integration Architecture

Solution Configuration in QRadar SIEM and Defender Zero Trust

Prerequisites

• Installed Security Edition
• Eyeglass OS appliance version 15.5 — verify with cat /etc/os-release
• License key for the Zero Trust API
• QRadar SIEM

Configuration in QRadar SIEM

1. Log in to the QRadar UI and ensure the default Syslog DSM is installed.

Configuration Steps on Eyeglass Virtual Machine

High-Level Steps

1. Create the Python location to run the application on the Eyeglass VM.
2. Create the Python main application script.
3. Create the Linux systemd service and set it to auto-start.
4. Create the Zero Trust configuration in Defender.
5. Update the main script to customize it with the QRadar SIEM Python code.
6. Test the script is running as a service.
7. Create a test event in Defender to validate alerts appear as indexed parsed events in QRadar SIEM.

Configure the Service Start and Python Integration Files

Log in to the Eyeglass VM via SSH as the admin user:

ssh admin@<your-vm-ip>

Become root:

sudo -s

mkdir -p /opt/superna/cgi-bin

chown -R sca:users /opt/superna/cgi-bin

chmod -R u+rwX,g+rwX /opt/superna/cgi-bin

Switch to the SCA user:

sudo -u sca -s

cd /opt/superna/cgi-bin

Create a Python virtual environment for the integration:

python3 -m venv venv-qradar

source venv-qradar/bin/activate

Install required Python packages:

pip install flask boto3 requests logging

deactivate

Create integration script files:

touch qradar.py

touch qradar.sh

chmod +x qradar.py

chmod +x qradar.sh

Create the qradar.sh launch script:

nano /opt/superna/cgi-bin/qradar.sh

Paste the following content into the file:

#!/bin/bash

export PATH="/opt/.pyenv/bin:$PATH"

source /opt/superna/cgi-bin/venv-qradar/bin/activate

exec python /opt/superna/cgi-bin/qradar.py

Make the script executable:

chmod +x /opt/superna/cgi-bin/qradar.sh

Exit back to root:

exit

whoami # confirm you are root

Create the systemd service unit file:

nano /etc/systemd/system/qradar.service

Paste the following content into the file:

[Unit]
Description=Webhook listener for Zero Trust API translations and integrations
After=network.target

[Service]
Type=simple
User=sca
Group=users
WorkingDirectory=/opt/superna/cgi-bin
ExecStart=/bin/bash /opt/superna/cgi-bin/qradar.sh
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

Reload systemd to register the new service:

systemctl daemon-reload

Enable the service to start on boot (do not start it yet):

systemctl enable qradar

Configure Python Packages and Customize the Integration Code

1. Download the Python template code from the link to download (right-click, save as).

2. Open the Python template file in a text editor. Only replace the placeholder values — do not delete any commas.

3. Locate the following section and replace the placeholder values with your QRadar endpoint IP address, port, and TCP flag:

   SYSLOG_SERVER = 'x.x.x.x'  # Replace with your syslog server address
   SYSLOG_PORT = 514            # Replace with your syslog server port
   FACILITY = 13                # Facility code for security audit log
   SEVERITY = 2                 # Severity level for critical messages
   USE_TCP = True               # Set to True for TCP, False for UDP

4. Open the production file on the Eyeglass VM:

   nano /opt/superna/cgi-bin/qradar.py

5. Open the template file locally in Notepad, select all (Ctrl+A), and copy.

6. Paste the clipboard into the SSH terminal session with the open nano editor.

7. Save the file:

   • Press Ctrl+X
   • Answer Yes to save and exit

8. Start the service and verify it is running:

   systemctl start qradar
   
   systemctl status -l qradar

   Verify the service returns "active and running". If the service does not start, do not proceed — double-check the steps above.

Configure Defender Zero Trust Webhooks

1. Configure the Zero Trust endpoint in the Ransomware Defender Zero Trust tab.

   Recommended Configuration

   Send only Critical and Major events, and only webhooks that set lockout or delayed lockout. The goal is to send findings rather than a list of alarms that do not pinpoint a security incident. Customers can customize based on specific requirements.

2. The endpoint URL uses localhost and sends webhooks to the application service listening on port 5000:

   http://localhost:5000/webhook

3. Add the Content-Type header with value application/json to complete the webhook configuration.

4. Click Save to commit the configuration.

5. Click Save on the main Webhook configuration page.

How to Test the Integration with QRadar SIEM

1. Install the QRadar SIEM agent on a test machine and record its IP address.
2. Get the IP address of the Eyeglass VM.
3. Download the curl command template and open it with a text editor:
   • Locate the IP address of Eyeglass at the very end of the text and replace it with the IP address of your Eyeglass VM.
   • Search for clientIPs":["172.31.1.45"] and replace only the IP address with the IP of the test machine running the QRadar SIEM agent. This simulates a Zero Trust alert on that host.
4. Copy all the text in the text editor.
5. SSH to the Eyeglass VM as the admin user.
6. Paste the entire CLI command to the SSH prompt to send sample data to the running Zero Trust application.

A successfully processed webhook test returns the following text in the SSH terminal:

done sending event to qradar and check for http 200 and success count in response

To review the process logs from the web application:

sudo -s

journalctl -f -u qradar

To log to a file and review with nano, showing only the most recent 250 lines:

journalctl -f -n 250 -u qradar > /tmp/ztwebhook.log

nano /tmp/qradar.log

The response code from the QRadar SIEM API call should show HTTP 200 status code and successCount 1 to indicate the event was successfully created.

Log in to QRadar SIEM and verify that a new incident is raised.

QRadar SIEM SecOps Administrators Integration Experience

Once the integration is complete, Superna Zero Trust events appear as indexed, parsed events in QRadar SIEM.
