Overview

Customers using Exabeam Fusion SIEM solution can now leverage a native integration that initiates native ingestion API alerts from Security Editions zero trust alerts.   Customers can augment the capabilities of Exabeam Fusion SIEM with threat intelligence and Cyber Storage capabilities of Superna Security Edition.

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

Solution Overview

Superna Defender Zero Trust API receives webhook alerts and parses the key data into a HTTPS API payload events that are sent to the SIEM collector endpoint url.  Exabeam Fusion SIEM (Security Information and Event Management) 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

1. Webhook to native HTTPS collector API alarm integration

Integration Architecture

Solution Configuration in Exabeam Fusion SIEM and Defender Zero Trust

Prerequisites

1. Installed Security Edition
2. Eyeglass OS appliance version 15.5
   1. cat /etc/os-release

2. Done

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 Exabeam Fusion SIEM 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 Exabeam Fusion SIEM

Configuration Step by Step

Configure the Service start and python integration files

1. Login to eyeglass vm using ssh as the admin user to create zero trust application
   1. sudo -s 
   2. mkdir -p /opt/superna/cgi-bin
   3. touch /opt/superna/cgi-bin/exabeam.py
   4. touch /opt/superna/cgi-bin/exabeam.sh 
   5. sca:users /opt/superna/cgi-bin/exabeam.*
   6. chmod +x  /opt/superna/cgi-bin/exabeam.py 
   7. chmod +x /opt/superna/cgi-bin/exabeam.sh 
2. Create systemd configuration
   1. nano  /etc/systemd/system/exabeam.service
   2. Copy the values below and Paste these contents into the file opened in nano editor in the step above
   3. Save the file 
      1. press control+x
      2. Answer yes to save and exit
3. Restart systemd
   1. systemctl daemon-reload
4. Set to enabled
   1. systemctl enable exabeam
5. Create exabeam.sh service script
   1. Copy the values below
   2. nano /opt/superna/cgi-bin/exabeam.sh
   3. paste the script values below into the nano editor
   4. Save the file
      1. press control+x
      2. Answer yes to save and exit the editor
6. Once the script is created below,  do not start the service at this step.
7. Done

Configure the python packages and customize the exabeam integration python code

1. Now install required python packages for the SCA users that will run the service.  NOTE this is the same user that runs the main eyeglass application code.
   3. su - sca  (you may need to install the packages as the root user)
   4. pip3 install flask boto3 requests logging
   5. exit 
   6. NOTE: you must type exit to ensure you are the root user for the remaining steps.  Type whoami to make sure you are the root user.
2. Customize the application code by downloading the python code from this link to download
   3. Open the python template file in a text editor. NOTE: make sure to only replace the values and do not delete any of the commas
   4. Locate this section in the file and replace the yellow sections to match your exabeam endpoint URL.   The endpoint url is unique and can be copied from the console into the variable below.
      3. exabeam_URL = ""
      4. exabeam_api_token = ""
3. nano /opt/superna/cgi-bin/exabeam.py
4. Open the file locally in Windows OS notepad and use control-A or select all the text in the python template
5. Paste the clipboard into the ssh terminal session with the open nano editor file
6. save the file
   3. press control+x
   4. Answer yes to save and exit the nano editor 
7. Start the service and verify it is running
   1. systemctl start exabeam
   2. systemctl status -l exabeam 
   3. Verify the service is started successfully and returns "active and running".
8. 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 Ransomware Defender Zero Trust 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 and the content-encoding with value gzip 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 Exabeam Fusion SIEM

1. To test the integration follow these steps
2. Prerequisites In Exabeam Fusion SIEMand Eyeglass:
   1. install the Exabeam Fusion SIEMagent on a test machine.  Record the ip address of this test machine.
   2. Get the ip address of the Eyeglass vm
   3. download this curl command template and open with a text editor and locate the ip address of eyeglass at the very end of text and replace the ip address with the IP address of your eyeglass vm.
   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 text 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 Exabeam Fusion SIEM Integration service that is running on the Eyeglass VM.
   7. The output of a successfully processed webhook test will return this text in the ssh terminal
      1. done sending event to exabeam and check for http 200 and success count in response
   8. How to review the process logs from the web application
      1. sudo -s 
      2. journalctl -f -u exabeam 
      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 exabeam  > /tmp/exabeam.log
      6. nano /tmp/exabeam.log
      7. In the log below the response code from the Exabeam Fusion SIEM api call should show http 200 status code and successCount 1 to indicate the Finding was successfully created.
      8.   You can also view exabeam.log for specific error messages.
   9.  
3. Done
