Configuring Imperva Incapsula Connectors

This connector allows Stellar Cyber to ingest logs from Imperva Incapsula and add the records to the data lake. It integrates the log files (including security logs and access logs) that are downloaded from the Imperva log repository to the Stellar Cyber Data Processor.

The availability of this feature depends on your subscription. For subscription plans, contact an Imperva sales representative.

Adding a Imperva Incapsula Connector

To add a Imperva Incapsula connector:

  1. Obtain credentials
  2. Add the connector in Stellar Cyber
  3. Test the connector
  4. Verify ingestion

Obtaining Imperva Incapsula Credentials

Before you configure the connector in Stellar Cyber, you must obtain the following Imperva Incapsula credentials:

  • Log Server URL. This is the URL of the Imperva log repository in the Imperva cloud. It is displayed in the Imperva Cloud Security Console Log Setup page.

  • API ID and API Key. See the following procedure.

Log in to your my.imperva.com account as an account administrator (or a user with permissions to manage API keys). The permissions are: Manage users and permissions and Manage API keys.

Follow guidance on Imperva documentation to create an API ID and key.

  1. In the Cloud Security Console, open the Account Users page. For details, see Account Users.

  2. Select a user row to open Settings.

  3. Click Add API Key to generate the API ID and Key.

  4. From the popup window, copy the generated API ID and key, which will be used to add the connector in Stellar Cyber.

    Store the API ID and key in a safe location. They cannot be retrieved later although they can be regenerated.

Adding the Connector in Stellar Cyber

To add a Imperva Incapsula 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 Web Security from the Category drop-down.

  5. Choose Imperva Incapsula 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 Log Server URL.

  13. Enter the API ID you obtained earlier.

  14. Enter the API Key you obtained earlier.

  15. Choose the Interval (min). This is how often Stellar Cyber checks the Imperva log server for new files to download.

  16. Click Next. The final confirmation tab appears.

  17. 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.
