Configuring Microsoft Entra ID (formerly Azure Active Directory) Connectors

This connector allows Stellar Cyber to collect data from external sources and add the records to the data lake and, optionally, to issue response actions.

Microsoft Entra ID (formerly Azure Active Directory) integration with Stellar Cyber provides advanced identity and access management capabilities, enabling organizations to manage user access and security policies across their network, and providing enhanced security controls and compliance features.

The user information from Microsoft Entra ID (formerly Azure AD) enriches event Interflow records and provides user profile details for User Behavior Analytics.  You can also disable (and re-enable) users for applicable events, and confirm a compromised user and dismiss the risk of a user.

If you have more than one Microsoft Entra ID, you must create one connector for each of them.

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.

Connector Overview: Microsoft Entra ID

Adding the Microsoft Entra ID Connector

To add the Microsoft Entra ID connector:

1. Register an application
2. Configure the application
3. Add the connector in Stellar Cyber
4. Test the connector
5. Verify ingestion

Registering an Application

Follow the instructions below to register an application and configure Microsoft Entra ID portal. During the process, make note of the following values for use when you create the connector later:

• Application (client) ID

• Directory (tenant) ID

• Secret Key (password)

1. With an administrative account, log in to the portal you use for Microsoft Entra ID administration of the Microsoft subscription (tenant) in which you want to register the Stellar Cyber application. (Example portals are: https://go.microsoft.com, portal.azure.com, and https://admin.microsoft.com/adminportal). If your account gives you access to more than one tenant, select your account icon and then the Microsoft Entra ID tenant that you want.

   The Dashboard appears.

2. Select Microsoft Entra ID from the left navigation pane.

3. In navigation pane, select App registrations. A pane for adding and managing App registrations is displayed.

   

4. Click New registration. A pane is opened for your new parameters.

   

5. Enter a Name.

6. Choose a supported account type. Accounts in this organizational directory only is typical.

7. The Redirect URI setting is not required.

8. Click Register. The registration is created and a summary of it is displayed.

   

9. Copy the following details to a file:

   • Display Name

   • Application (client) ID

   • Directory (tenant) ID

You are now ready to configure the application.

Configuring the Application

1. To set the access to the application, under App registrations in the navigation pane under Manage, select Manifest.

   

   1. In the Microsoft Graph App Manifest (New), locate the field for isFallbackPublicClient and set it to true.

   2. Click Save.

2. To create your secret key, in the navigation pane under Manage, select Certificates & secrets.

   

   1. Click New client secret. The Add a client secret pane is displayed.

   2. Enter a Description.

   3. Choose an expiration.

   4. Click Add. The secret key is created and is now displayed in the Client secrets list.

      

   5. Copy the Value. This is the Password you will use to add the connector in Stellar Cyber.

3. To set the permissions for your application, in the navigation pane under Manage, select API Permissions. The API permissions pane appears.

   

   1. Click Add a permission. The Request API permissions pane appears.

      

   2. Click Microsoft Graph. The pane updates to offer Delegated permissions or Application permissions.

   3. Click Application permissions.

      

      The pane updates to display options for setting permissions.

      

   4. Set the following permissions for the logs you want to collect.

      Logs	API Permission	License Required
      Audit	AuditLog.Read.All	Microsoft Entra ID Free
      Sign in	AuditLog.Read.All Directory.Read.All	Microsoft Entra ID P1 or P2
      Risk detection security reports	IdentityRiskEvent.Read.All	Microsoft Entra ID P1 or P2
      Risky user security reports	IdentityRiskyUser.Read.All	Microsoft Entra ID P2
      User profile	User.Read.All	None

   5. Click Add permissions. The API permissions page redisplays with your added permissions.

   6. If you are the super admin, grant the permissions. Select the checkmark to Grant admin consent for <account name>.

      Otherwise, wait for the super admin to grant them.

      Make sure that the permissions are granted. If you add the connector before permissions are granted, the process fails.

      

      When the permissions are granted successfully, there will be a green checkmark in the Status column.

4. If your connector will be used for respond actions, the API must also be configured with application permissions. From the API Permissions pane, click Add a permission again.

   

   1. In the Request API permissions pane, click Microsoft Graph.

   2. Click Application permissions.

   3. For the Disable User response action, enable User.EnableDisableAccount.All and User.ReadWrite.All. For the Confirm Compromised and Dismiss Risk response actions, enable IdentityRiskyUser.ReadWrite.All.

   4. Click Add permissions. The API permissions page re-displays with your added permissions.

The permissions can take up to two hours to propagate to historical data. We suggest you add the permissions at least two hours prior to adding the connector in Stellar Cyber, as Stellar Cyber will try to pull historical logs when first configured.

Adding the Connector in Stellar Cyber

With the application registered, permissions granted, and the access information handy, you can add the Microsoft Entra ID 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 Microsoft Entra ID (formerly Azure Active Directory) from the Type drop-down.

6. For Function, enable the Collect checkbox. If you would like to issue response actions, also enable 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.

   • 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 Application ID you copied earlier.

13. Enter the Directory ID you copied earlier.

14. Enter the Password you copied earlier.

15. Select the applicable Microsoft Entra ID Subscription Plan from the menu:

    • Enterprise Plan

    • GCC Government Plan

    • GCC High Government Plan

    • DoD Government Plan

    To learn about Microsoft Entra ID government plans, refer to the following Microsoft documentation: https://learn.microsoft.com/en-us/azure/security/fundamentals/feature-availability.

    The Government Plans do not support the Sign-in Logs content type.

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

17. Choose the logs you want to collect. These must match the permissions you set in Microsoft Entra ID. None are collected by default, so you must select at least one log. Note the following:

    Log	Required License	Required Permissions	Alert Integration
    Audit Log	Microsoft Entra ID Free	AuditLog.Read.All	No
    Sign-in Logs	Microsoft Entra ID P1 or P2	AuditLog.Read.All Directory.Read.All	No
    Risk Detection	Microsoft Entra ID P1 or P2	Identity.RiskEvent.Read.All	Mapped to Stellar Cyber Alerts
    Risky User	Microsoft Entra ID P2	Identity.RiskyUser.Read.All	Mapped to Stellar Cyber Alerts
    User Profile	N/A	User.Read.All	No

    When the new connector is first active, it will collect logs for the content types as follows:

    Log	Log Collection for First Data Pull
    Audit Log	1 hour
    Sign-in Logs	1 hour
    Risk Detection	15 days
    Risky User	15 days
    User Profile	from the beginning

18. (Optional) Stellar Cyber allows you to customize the scope of the request the collector should request for the selected log type. For example, specifying 60 minutes specifies that when the collector requests data, the request should delay completion until a full 60 minutes of data has been collected. To override the default delays, check the box at the top of the page for Advanced Settings. Any of the logs you selected now display a configurable delay field.

    

19. Click Next. The final confirmation tab appears.

    

20. Click Submit.

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

21. 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.

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.

Verifying Ingestion

To verify ingestion:

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