Adding the Connector in Stellar Cyber

To add a CyberCNS 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 Vulnerability Scanner from the Category drop-down.

  5. Choose CyberCNS 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 Domain Name. For example, portaluseast2.mycybercns.com or portaluswest2.mycybercns.com.

    Do not include the http/https prefix.

  13. Enter the Tenant Name. This is the name of the CyberCNS tenant.

  14. Enter the Client ID you noted above in Obtaining CyberCNS Credentials.

  15. Enter the Client Secret you noted above in Obtaining CyberCNS Credentials.

  16. Choose the Interval (min). This is how often this connector retrieves data from CyberCNS. The default interval is 60 minutes.

  17. Choose the Content Type you would like to collect. The logs for Vulnerabilities are supported.

  18. Click Next. The final confirmation tab appears.

  19. 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.
