Configuring Google Workspace Connectors

This connector allows Stellar Cyber to collect data from external sources and add the records to the data lake.

Integrating Google Workspace with Stellar Cyber provides real-time visibility into security events and alerts across cloud and on-premise environments, enabling organizations to effectively monitor and respond to security incidents. Stellar Cyber's advanced security analytics and machine learning algorithms provide real-time threat detection and response capabilities, while also providing advanced identity and access management capabilities to manage user access and security policies.

You must have one connector for every Google Workspace account to be monitored.

This connector is improved to use less memory. Under certain scenarios if there is an error reaching the third-party API, some duplicate messages may be sent.

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.

• For Application reports, include this scope: https://www.googleapis.com/auth/admin.reports.audit.readonly

  (The application types are listed in the Stellar Cyber connector configuration dialog.)

7. Click Authorize.

You now have an authorized Client ID with OAuth scopes.

Adding the Connector in Stellar Cyber

With the Google service account set up and the API key ready, you can add a Google Workspace connector in Stellar Cyber:

1. Log in to Stellar Cyber.

2. Click System | Connectors (under Integrations). 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 SaaS from the Category drop-down.

5. Choose Google Workspace (Gsuite) 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.

   • 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 you select Data Processor, you will need to associate the connector with a Data Analyzer profile as a separate step. That step is not required for a sensor, which is configured with only one possible profile.

   • 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. (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 Admin Email for the account administrator (not the email created by Google for the service account).

13. For API Scopes, enter the OAuth scopes you added in Adding the Client ID with OAuth Scopes. Stellar Cyber provides the following scopes by default: 

    • For Alert reports, include this scope: https://www.googleapis.com/auth/apps.alerts

      The alert scope is required if you would like Stellar Cyber to integrate the Gmail Phishing alert to the XDR Kill Chain.

    • For Application reports, include this scope: https://www.googleapis.com/auth/admin.reports.audit.readonly

    Separate additional scopes with commas.

14. Upload the Service Account Key File, which is the API file you downloaded in Creating an API Key.

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

16. Enter the Query Delay (min).

17. Choose the App you want to collect by selecting them from the drop-down menu.

    Content Type (App Name)	Report type	Required Scope
    Admin	Admin Console activities of all of your account's administrator activity	https://www.googleapis.com/auth/admin.reports.audit.readonly
    Alert	Google Alert Center reports		https://www.googleapis.com/auth/apps.alerts
    Calendar	Google Calendar application's activity audit reports
    Chat	Chat activity audit reports
    Drive	Google Drive application's activity reports
    Gplus	Google+ / Currents application activity reports
    Groups	Google Groups audit reports
    Login	Login audit events
    Mobile	Device audit events
    Rules	Reports for rule related events
    SAML	SAML audit reports
    Token	OATH Token Audit events

18. Click Next. The final confirmation tab appears.

    

19. Click Submit.

    To pull data, a connector must be added to a Data Analyzer profile if it is running on the Data Processor.

20. If you are adding rather than editing a connector with the Collect function enabled and you specified for it to run on a Data Processor, a dialog box now prompts you to add the connector to the default Data Analyzer profile. Click Cancel to leave it out of the default profile or click OK to add it to the default profile.

    • This prompt only occurs during the initial create connector process when Collect is enabled.

    • Certain connectors can be run on either a Sensor or a Data Processor, and some are best run on one versus the other. In any case, when the connector is run on a Data Processor, that connector must be included in a Data Analyzer profile. If you leave it out of the default profile, you must add it to another profile. You need the Administrator Root scope to add the connector to the Data Analyzer profile. If you do not have privileges to configure Data Analyzer profiles, a dialog displays recommending you ask your administrator to add it for you.

    • The first time you add a Collect connector to a profile, it pulls data immediately and then not again until the scheduled interval has elapsed. If the connector configuration dialog did not offer an option to set a specific interval, it is run every five minutes. Exceptions to this default interval are the Proofpoint on Demand (pulls data every 1 hour) and Azure Event Hub (continuously pulls data) connectors. The intervals for each connector are listed in the Connector Types & Functions topic.

    The Connector Overview appears.

The new connector is immediately active. It does not collect any historical logs.

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).

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.

An error displays If you use an email address that doesn't have privileges to add the connector, or if you created the service account but it is not yet authorized.

Verifying Ingestion

To verify ingestion:

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

2. Change the Indices to Linux Events or AWS Events. The table immediately updates to show ingested Interflow records.
