Configuring Duo Security Connectors

This connector allows Stellar Cyber to collect data from external sources and add the records to the data lake.

Integrating Duo with Stellar Cyber provides advanced identity and access management capabilities, enabling organizations to manage user access and security policies across their network, and providing enhanced security controls and compliance features. By combining Duo's multi-factor authentication with Stellar Cyber's advanced security analytics and machine learning algorithms, organizations can effectively defend against cyber threats.

Note that the API for Duo Security is not supported for deployments configured to communicate through an HTTP proxy.

Adding a Duo Security Connector

To add a Duo Security connector:

  1. Configure Duo Security application protection
  2. Add the connector in Stellar Cyber
  3. Test the connector
  4. Verify ingestion

Configuring Duo Security Application Protection

To configure Duo Security application protection:

Use our example as a guideline, as you might be using a different software version.

  1. Log in to Duo.

  2. If you don't have the Admin API application available, contact Duo technical support and request access. When you get access, continue.

  3. Click Applications. The Application menu expands.

  4. Click Protect an Application. The Protect an Application page appears.

  5. Find Admin API. If you start typing in the search bar, the available applications narrow to match the text you type.

  6. Click Protect on the Admin API row. The Admin API page appears.

  7. Copy the Integration key, Secret key, and API hostname. You need all of these when configuring Stellar Cyber.

  8. Configure the Settings. At a minimum, select the following permissions: Grant read information, Grant read log, and Grant read resource.

  9. Click Save.

Adding the Connector in Stellar Cyber

To add a Duo 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 IdP from the Category drop-down.

  5. Choose Duo Security from the Type drop-down.

  6. For this connector, the supported Function is Collect, 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.

  10. (Optional) When the Function is Collect, you can create Log Filters. For information, see Managing Log Filters.

  11. Click Next. The Configuration tab appears.

    The asterisk (*) indicates a required field.

  12. Enter the Hostndupame. This is the Duo API hostname you copied earlier. (Do not include https in this field.)

  13. Enter the Integration Key you copied earlier.

  14. Enter the Security Key you copied earlier.

  15. Choose the Interval (min). This is how often the logs are collected.  

    Note that default setting is 5 minutes, which is the minimum recommended interval for this connector type.

  16. Choose the Content Type you would like to collect. The logs for Administrator, Authentication, and Telephony are supported.

  17. Click Next. The final confirmation tab appears.

  18. Click Submit.

    To pull data, a connector must be added to a Data Analyzer profile if it is running on the Data Processor.

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).

For connectors running on a sensor, Stellar Cyber recommends that you allow 30-60 seconds for new or modified configuration details to be propagated to the sensor before performing a test.

  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.
