Home



 

Overview

Customers using Defense.com can leverage this integration to send real time zero trust alerts using webhooks and maintain full payload parsing using json defined fields.   The Defense.com Alert Ingestion Connector capability within the platform allows inbound webhook json payload to be parsed within the SIEM.    


Support Statement

  1. NOTE:  This documentation is provided "as is" without support for 3rd party software.  The level of support for this integration guide is best effort without any SLA on response time.  No 3rd party product support can be provided by Superna directly.  3rd party components require support contracts

Limitations

  1. NOTE: This guide does not provide any configuration for routes, pipelines or destinations.  It is assumed customers will configure where the alert data should be routed and sent to destinations.

Configuration Steps on Eyeglass Virtual Machine

High Level steps

  1. Create python location to run the application on the Eyeglass vm
  2. Create python main application script
  3. Create linux systemd service and set to auto start
  4. Create Zero Trust configuration in Defender
  5. Update the main script to customize with Defense.com  python code
  6. Test the script is running as a service
  7. Create a test event in Defender to validate the alerts appear as indexed parsed events in Defense.com

Configuration Step by Step

  1. Login to the eyeglass VM as admin user
  2. Follow the steps below
Configure the Service start and python integration files
# Integration Deployment Instructions

Login 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 Python virtual environment for the integration
python3 -m venv venv-defense 
source venv-Defense.com/bin/activate

# Install required Python packages
pip install flask boto3 requests logging
deactivate

# Create integration script files
touch defense.py
touch defense.sh
chmod +x defense.py
chmod +x defense.sh

# Create the Defense.com.sh launch script
nano /opt/superna/cgi-bin/defense.sh
# Paste the following into the file:
#!/bin/bash
export PATH="/opt/.pyenv/bin:$PATH"
source /opt/superna/cgi-bin/venv-defense/bin/activate
exec python /opt/superna/cgi-bin/defense.py

# Make the script executable
chmod +x /opt/superna/cgi-bin/defense.sh

# Exit back to root
exit
whoami # confirm you are root

# Create the systemd service unit file
nano /etc/systemd/system/.service
# Paste the following 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/defense.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 defense 
Configure the python packages and customize the Defense.com integration python code


  1. Customize the application code by downloading the python code from this link to download (right click download as)
    1. Open the python template file in a text editor. NOTE: make sure to only replace the yellow values (endpoint url for http ingestion of your Defense.com instance, the api token)
    2. Locate this section in the file, replace yellow highlights.    Change the port if different from below. 
      1. # === Defense.com Configuration ===
        DEFENSE_SYSLOG_HOST = "x.x.x.x" # <-- change
        DEFENSE_SYSLOG_PORT = 5514 # UDP 5514

    3. Paste the updated script into the production file
      1. nano /opt/superna/cgi-bin/defense.py
      2. Open the file locally in Windows OS notepad and use control-A or select all the text.
      3. Paste the clipboard into the ssh terminal session with the open nano editor file
      4. save the file
        1. press control+x
        2. Answer yes to save and exit the nano editor 
  2. Start the service and verify it is running
    1. systemctl start defense
    2. systemctl status -l defense 
    3. Verify the service is started successfully and returns "active and running".
  3. If the service does not start do not proceed and double check the steps above are completed. 

Configure Defender Zero Trust Webhooks

  1. The next step creates an Zero Trust Webhook URL.    
    1. Configure Zero Trust endpoint in Integrations icon, Webhooks tab.
      1. Recommended Configuration: Only Critical and Major events and only the webhooks that set lockout or delayed lockout.   Customers can customize based on specific requirements. The goal is to send findings versus a list of alarms that do not pinpoint a security incident.
      2.    
      3. The endpoint url above will use localhost and will send Webhooks to the application service listening on port 5000. URL to use in the configuration
        1. http://localhost:5000/webhook
        2. Add the Content-Type header with value of application/json as shown above to complete the webhook configuration.
        3. Click save to commit the configuration.
        4. Click save on the main Webhook configuration page
  2. Test the configuration is working following the next section

How to test the Integration with Defense.com

  1. To test the integration follow these steps
    1. download this curl command template and open with a text editor
    2. Copy all the text
    3. ssh to the eyeglass vm as the admin user
    4. paste the entire cli command to the ssh prompt to send sample data to the running Zero Trust application.  This will send test data directly to the application to be processed and sent to Defense.com.
    5. The output of a successfully processed webhook test will return this text in the ssh terminal
      1. done sending event to abssiem and check for http 200 and success count in response
    6. How to review the process logs from the web application
      1. sudo -s 
      2. journalctl -f -u defense 
      3. This allows you to view the logs generated by the application.
      4. To log to a file and review with nano showing only the most recent 250 lines.
      5. journalctl -f -n 250 -u defense  > /tmp/ztwebhook.log
      6. nano /tmp/ztwebhook.log 
      7. In the log below the response code from the Defense.com api call should show sending status code
  2. Done
