Third Party Native Alert Integration Details

Devices

This content is not applicable for alerts.

Events

Yes. Records with MITRE | ATT&CK values are de-duplicated, enriched with Stellar Cyber fields, and mapped to the Stellar Cyber xdr_event record. If the incoming Tactic or Technique are blank, the following values are assigned in Stellar Cyber:
tactic_name= XDR Malware
technique_name = XDR Miscellaneous Malware

Suspicious events

No.

 For details, see Integration of Third Party Native Alerts.

Required Credentials

  • Hostname and API Token

  • To Collect, the API token must be created with at least READ_ONLY permission

  • For Response, READ_AND_REMEDIATION permissions are required

Locating Records

Use the following to query for records:

  • msg_origin.vendor: deep_instinct

  • msg_origin.category: asset, endpoint

  • msg_origin.source: deep_instinct

  • msg_class: deep_instinct_asset, deep_instinct_maliciousevent, deep_instinct_suspiciousevent

               Let us know if you find the above overview useful.

Adding a Deep Instinct Connector

To add a Deep Instinct connector:

  1. Obtain a Deep Instinct API token
  2. Add the connector in Stellar Cyber
  3. Test the connector
  4. Verify ingestion

Obtaining a Deep Instinct API Token

As part of this procedure, you specify the credentials of an account on the Deep Instinct server that will be used to retrieve data.

  1. Log into your Deep Instinct Dashboard as an administrative user. Make note of the fully qualified domain name portion of the URL you used to log in (e.g., just mycompany.customer.deepinstinct.com). You will need this when you configure the Stellar Cyber connector.

  2. From the Dashboard navigation pane, select Integration & Notification.

  3. In the pane that loads, click the link for API Connectors, shown above.

  4. Click the button to Create an API Connector.

  5. In the Add API Connector dialog, create a name, select the Tenants you want to be able to use this API connector with Stellar Cyber and specify the Permissions. The minimum permission required is READ_ONLY. For Respond actions , you must include READ_AND_REMEDIATION permissions.

  6. Click OK to save the settings and create the API Key. The API Connectors pane displays.

  7. Click the API key you created to display it, then copy the key.  Save that key for use when you configure the Stellar Cyber connector.

Adding the Connector in Stellar Cyber

To add the Deep Instinct 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 Endpoint Security from the Category drop-down.

  5. Choose Deep Instinct from the Type drop-down.

  6. Choose whether you want to only Collect or also Respond.

  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 Hostname. This is the FQDN portion of the URL you used for your Deep Instinct dashboard login, above (for example, mycompany.customer.deepinstinct.com).

  13. Do not include https in the field.

  14. In the API Token field, enter the API key you created above.

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

  16. Choose the Content Type. The logs for Devices, Events, and Suspicious Events are supported. Events are mapped to Stellar Cyber Alerts.

  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.

Verifying Ingestion

To verify ingestion:

  1. Click Investigate | Threat Hunting. The Interflow Search tab appears.

  2. Set the Indices to match the type of content you collected:

    • For Devices, change the Indices to Syslog or Assets. Note that hosts discovered through this connector show Deep Instinct as a data source.

    • For Events, change the Indices to Syslog or Alerts.

    • For Suspicious Events, change the Indices to Syslog.
