Configuring Trend Micro Cloud One Workload Security Connectors

This connector allows you to discover Trend Micro Cloud One Workload Security managed computer assets, and add them to the Stellar Cyber data lake for analysis and threat hunting.

This topic refers to configuring a Trend Micro Cloud One Workload Security connector. Also see: 

• Configuring Trend Micro Apex Central Connectors
• Configuring Trend Micro Vision One Connectors

Stellar Cyber connectors with the Collect function (collectors) may skip collecting some data when the ingestion volume is large, which potentially can lead to data loss. This can happen when the processing capacity of the collector is exceeded.

Adding a Trend Micro Cloud One Connector

To add a Trend Micro Cloud One Workload Security connector:

1. Obtain Authentication details for Stellar Cyber integration
2. Add the connector in Stellar Cyber
3. Test the connector
4. Use the connector

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

Obtaining Authentication Details for Stellar Cyber Integration

Before you add a Trend Micro Connector, you must obtain information that allows the Stellar Cyber connector to authenticate correctly.

1. Log in to the Trend Micro Cloud One console as the user who will be associated with the Stellar Cyber app (http://cloudone.trendmicro.com).

2. When the console has loaded, access the Workload Security screen: 

   

3. Navigate to Administration > User Management > API.

   

4. Click Add. In the displayed dialog, add the following:

   • Name: This is the name you will use to identify the app as being associated with Stellar Cyber

   • Role: Select Full Access.

   

5. Click Next.

6. The dialog updates to display the secret key for your new app. Make note of this for use when you configure your connector. You cannot retrieve this key after you close the dialog, so make note of it now. If you accidentally lose the information, you must create a new app.

   

7. Click Close.

   The API Keys screen appears and shows the newly added application in the table.

Adding the Connector in Stellar Cyber

After you have noted the authentication information from the Trend Micro app integration steps, you can add the Trend Micro Cloud One Workload Security 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 Trend Micro Cloud One Workload Security from the drop-down.

6. For this connector, the supported Function is Collect, which is enabled already.

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 for the tenants who will have access to this connector.

9. Choose the device on which to run the connector.

10. (Optional) When the Function is Collect, you can apply Log Filters. For information, see Managing Log Filters.

11. Click Next. The Configuration tab appears.

    

    The asterisk (*) indicates a required field.

12. Enter the API URL. This is the API URL associated with the API key. Trend Micro legacy format is https://cloudone.trendmicro.com/api , but migrated to a regional format as follows: https://workload.{region}.cloudone.trendmicro.com/api (example: https://workload.us-1.cloudone.trendmicro.com/api/).

    For release versions prior to v4.3.4, ensure the URL does not include a trailing "/" symbol.

13. Enter the API Key. This is the Secret Key associated with the application you created above in the Trend Micro Cloud One Workload Security console.

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

15. Choose the Content Type you would like to collect. The logs for Computers are supported.

    Stellar Cyber gets the computer object, normalizes some of the fields, creates an asset record, and populates Syslog. The fields in Syslog are trendmicro_cloudone.<fieldname>, which may include any of the fields for Computers as follows: https://cloudone.trendmicro.com/docs/workload-security/api-reference/tag/Computers

    In addition, the computers are sent to the Investigate | Asset Analytics page.

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.

Using the Connector to Investigate

When an event has occurred on a host known to the Trend Micro connector, you can use this connector to investigate further.

1. Click Investigate | Threat Hunting. The Interflow Search tab appears.
2. Change the Indices to Syslog. The table immediately updates to show ingested Interflow records.
