Adding a Barracuda Email Connector

To add a new Barracuda email connector:

  1. Verify the Barracuda configuration
  2. Enable API Access / Obtain Credentials
  3. Add the connector in Stellar Cyber
  4. Test the connector

Verifying the Barracuda Configuration

This connector is intended to support deployments with Barracuda already integrated. The following are needed before you proceed:

  1. You must already have a Barracuda Cloud Control / Email Protection account set up. (https://ess.barracudanetworks.com/)

  2. Your email service must already be integrated with Barracuda Email Security as a gateway. (Steps are provided on the Barracuda documentation website.)

  3. Configure SYSLOG parsing for port 5559 on the Barracuda email server and on your Stellar Cyber sensor.

Enabling API Access

  1. Use the Barracuda token service to register an application for communication between Stellar Cyber and the Barracuda Email Gateway Defense system. Log in to: https://login.bts.barracudanetworks.com/register. (Steps are also provided on Barracuda's documentation site.)

  2. Click Add Application.

  3. Ensure you select the option to permit read/write, which allows you to submit response actions from Stellar Cyber.

  4. After you save the application, make note of the Client ID and Client Secret. If you forget these, you can retrieve the ID but not the secret, you would need to use the token web page to reset the secret.

Adding the Connector in Stellar Cyber

To add a Barracuda Email Security connector in Stellar Cyber:

  1. Log in to Stellar Cyber.

  2. Click System | Integration | Connectors. The Connector Overview appears.

  3. Click Create. The General tab of the Add Connector screen appears. The information on this tab cannot be changed after you add the connector.

    The asterisk (*) indicates a required field.

  4. Choose Email from the Category drop-down.

  5. Choose Barracuda Email Security from the Type drop-down.

  6. For this connector, the supported Function is Respond, which is enabled already.

  7. Enter a Name.

    This field does not accept multibyte characters.

  8. Choose a Tenant Name. The Interflow records created by this connector include this tenant name.

  9. Choose the device on which to run the connector.

    • Certain connectors can be run on either a Sensor or a Data Processor. The available devices are displayed in the Run On menu. If you want to associate your collector with a sensor, you must have configured that sensor prior to configuring the connector or you will not be able to select it during initial configuration. If you select Data Processor, you will need to associate the connector with a Data Analyzer profile as a separate step. That step is not required for a sensor, which is configured with only one possible profile.

    • If the device you're connecting to is on premises, we recommend you run on the local sensor. If you're connecting to a cloud service, we recommend you run on the DP.

  10. Click Next. The Configuration tab appears.

    The asterisk (*) indicates a required field.

  11. Enter the Client ID and Client Secret noted in the previous section.

  12. Click Next. The final confirmation tab appears.

  13. Click Submit.

The new connector is immediately active.

Testing the Connector

When you add (or edit) a connector, we recommend that you run a test to validate the connectivity parameters you entered. (The test validates only the authentication / connectivity; it does not validate data flow).

  1. Click System | Integrations | Connectors. The Connector Overview appears.

  2. Locate the connector that you added, or modified, or that you want to test.

  3. Click Test at the right side of that row. The test runs immediately.

    Note that you may run only one test at a time.

Stellar Cyber conducts a basic connectivity test for the connector and reports a success or failure result. A successful test indicates that you entered all of the connector information correctly.

To aid troubleshooting your connector, the dialog remains open until you explicitly close it by using the X button. If the test fails, you can select the  button from the same row to review and correct issues.

The connector status is updated every five (5) minutes. A successful test clears the connector status, but if issues persist, the status reverts to failed after a minute.

Repeat the test as needed.
