Configuring Cynet Connectors

The Cynet connector allows you to lock down a device that is associated with an event reported by another connector. In Stellar Cyber, this connector is used to contain (isolate) or shut down the host, using Stellar Cyber actions.

If you use a Cynet connector to perform a Contain Host or Shutdown Host action on a host that is already disabled, shutdown, or otherwise not reachable, Cynet returns a status that the request was successful which is reported in the Stellar Cyber UI. If you are not certain whether an action was successful, you may verify it in the Cynet dashboard.

Adding a Cynet Connector

To add a Cynet connector in Stellar Cyber:

Obtain Cynet credentials
Add the connector in Stellar Cyber
Test the connector

Obtaining Cynet Credentials

To configure your Cynet connector in Stellar Cyber, you will need the following information from your Cynet deployment:

URL for the Cynet API access (https://pov.api.cynet.com/)
Username
Password
Client ID for the tenant (site) you want to manage (for MSSP configurations, you can find the client id in Global Settings > Client Site Manager > Sites Status)

Adding the Connector in Stellar Cyber

With the configuration information handy, you can add the Cynet connector in Stellar Cyber:

Log in to Stellar Cyber.
Click System | Integration | Connectors. The Connector Overview appears.
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.
Choose Endpoint Security from the Category drop-down.
Choose Cynet from the Type drop-down.
For this connector, the supported Function is Respond, which is enabled already.
Enter a Name.

This field does not accept multibyte characters.
Choose a Tenant Name. The Interflow records created by this connector include this tenant name.
Choose the device on which to run the connector.
Click Next. The Configuration tab appears.

The asterisk (*) indicates a required field.
Enter the Host URL. This is the URL noted above for API access.

For release versions prior to v4.3.4, ensure the URL does not include a trailing "/" symbol.
Enter the Username you copied earlier.
Enter the Password you copied earlier.
Enter the Client ID you copied earlier.
Click Next. The final confirmation tab appears.
Click Submit.

The new connector is immediately active. You can now contain hosts from the event display, and view or edit those actions on the Endpoint Actions page.

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.

Click System | Integrations | Connectors. The Connector Overview appears.
Locate the connector that you added, or modified, or that you want to test.
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.
