Configuring BlackBerry Cylance Connectors

The BlackBerry Cylance 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 for lock down only, not event tracking.

The devices you want to lock down using this connector must be configured using BlackBerry's CylancePROTECT Console to have a policy that permits device control (or to be in a zone configured with a policy that has device control enabled).

In addition, you can use Cylance responders to configure Webhook actions that can be triggered manually or that can enhance Automated Threat Hunting (ATH) actions.

Cylance responders use Webhook templates that support actions. Each action is one responder, there are four actions, and hence there are four Cylance responders: Cylance Add to GlobalQuarantine, Cylance Add to GlobalSafe, Cylance Delete from GlobalQuarantine, and Cylance Delete from GlobalSafe.

This document describes how to configure a Cylance responder using the Universal Webhook Responder, how to add the respond function to a Cylance connector and how to manually trigger an action and perform ATH actions with a Cylance responder.

Third Party Native Alert Integration Details

For CylancePROTECT, three types of Cylance events are mapped to the XDR Kill Chain and Stellar Cyber's Alert index: Exploit Attempts, Script Control, and Threats. The other data (Audit Log, Device, Device Control, and Threat Classification) are ingested and mapped to the Syslog index (not Alerts index), and are not run through the ML/SA pipeline.

For CylanceOPTICS, Detection events are evaluated with Stellar Cyber time series analysis models to determine abnormality of the event before mapping.

 For details, see Integration of Third Party Native Alerts.

Required Credentials and Configurations

  • Service Endpoint URL, Tenant ID, App ID, and App Secret

Locating Records

Use the following to query for records:

  • msg_origin.source: cylance_protect or cylance_optics

  • msg_class: cylance_protect_alert or cylance_optics_event

To search the alerts in the Alerts index or to search the Original Records in the Syslog index, use the query: msg_origin.source:cylance_protect AND event.type:(ExploitAttempt OR ScriptControl OR Threat)

Adding a Blackberry Cylance Connector

To add a Blackberry Cylance connector:

  1. Set up Stellar Cyber in CylancePROTECT and obtain IDs
  2. Add the connector in Stellar Cyber
  3. Add the connector in (Webhook Responder)
  4. Test the connector
  5. Use the connector
  6. Use actions

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

Setting up the Stellar Cyber App Integration

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

  • App ID and App Secret

  • Tenant ID

  1. Log in to the CylancePROTECT Console as an administrator.

  2. Select Settings > Integrations.

  3. Click Add Application.

  4. Type an Application Name. This must be unique within your organization.

  5. Select the access privileges for a Console data type. Not selecting any checkboxes for a data type means the application does not have access to that data type.

  6. Click Save.

  7. The credentials to use for the application displays. Make note of both the Application ID and the Application Secret.

  8. Click OK to return to the Integrations tab.

  9. Note that your new application appears in the list. At this point, make note of the Tenant ID that is displayed on the Integrations tab.

    The syntax of the Tenant ID must be exactly as it appears here.

You are now ready to set up your Stellar Cyber Cylance connector.

  7. Enter a Name.

    Notes:
    • This field does not accept multibyte characters.
    • It is recommended that you follow a naming convention such as tenantname-connectortype.

  8. Choose a Tenant Name. This identifies which tenant is allowed to use the connector. In addition to specific tenants, this connector supports All Tenants, which means that a Cylance responder can be used across tenants.

  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 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 Hostname you noted above (the URL of your regional BlackBerry Cylance portal).

  12. Select the Protocol, either HTTP or HTTPS. If you select HTTPS, another field is available: Disable SSL Certificate Verification.

  13. (Optional) Click Disable SSL Certificate Verification if you want to disable SSL certificate verification. Only disable SSL certificates if you have a reason to, otherwise, it is not a good security practice.

  14. Enter the Tenant ID you noted above.

    The syntax of the Tenant ID must be exactly as it appeared in the Integration tab of the Cylance Console.

  15. Enter the App ID and App Secret you noted above.

  16. Click Next. The final confirmation tab, Done, appears.

  17. Click Submit.

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 authentication and connectivity).

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 | Connectors (under Integrations). The Connector Overview appears.

  2. Locate the connector by name 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.

If the test fails, the common HTTP status error codes are as follows:

HTTP Error Code HTTP Standard Error Name Explanation Recommendation
400 Bad Request This error occurs when there is an error in the connector configuration.

Did you configure the connector correctly?
401 Unauthorized

This error occurs when an authentication credential is invalid or when a user does not have sufficient privileges to access a specific API.

Did you enter your credentials correctly?

Are your credentials expired?

Are your credentials entitled or licensed for that specific resource?
403 Forbidden This error occurs when the permission or scope is not correct in a valid credential.

Did you enter your credentials correctly?

Do you have the required role or permissions for that credential?

404 Not Found This error occurs when a URL path does not resolve to an entity. Did you enter your API URL correctly?
429 Too Many Requests

This error occurs when the API server receives too much traffic or if a user’s license or entitlement quota is exceeded.

The server or user license/quota will eventually recover. The connector will periodically retry the query.

If this occurs unexpectedly or too often, work with your API provider to investigate the server limits, user licensing, or quotas.

For a full list of codes, refer to HTTP response status codes.

Using the Connector to Contain a Host

When an event has occurred on a host known to the BlackBerry Cylance connector, you can use this to isolate the associated host. From the Event list in Investigate | Threat Hunting, you can select the event of interest, then click More Info.  From there, you can select External Action | Endpoint | Contain Host. In the displayed Contain Host Action Configuration block, select the relevant connector and in the Target, specify the source or destination host to lock down.

For more information on working with the events and the actions on them, refer to Understanding Event Details.
