Onboard an Office 365 App to SSPM Using a Service Principal

1. Log in to the administrator account that you will use to create your Microsoft Entra application and its associated service principal.

   Required Permissions: The administrator must be able to grant access to the API scopes required by SSPM. These scopes will differ depending on whether you want to grant SSPM read and write permissions, or if you want to grant SSPM read permissions only. In SSPM, the Office 365 onboarding screen lists the scopes that SSPM requires.

   After SSPM connects to your Office 365 instance, it will perform an initial scan of your instance, and will then run scans at regular intervals. For SSPM to run these scans, the service principal must remain available. If you delete the service account, the scans will fail and you will need to onboard Office 365 again.

   1. Open a web browser to the Microsoft Entra admin center.
   2. Log in to the administrator account.
2. Create and register your Microsoft Entra application.

   1. From the left navigation pane in the Microsoft Entra admin center, select Enterprise applications.
   2. On the Enterprise applications page, select the action to create a New application.
   3. On the All applications page, select Create your own application.
   4. On the Create your own application flyout dialog, complete the following actions:

      1. Specify a name for the application.
      2. Select Register an application to integrate with Microsoft Entra ID (App you're developing).
      3. Create.

   5. On the Register an application window, complete the following actions:

      1. For supported account types, select Accounts in this organizational directory only.
      2. Register.

      Registering the application automatically creates its associated service principal.
3. Configure API permissions for your application.

   Configure your application to enable access only to the scopes that SSPM requires. The API permissions that you will configure for your application depend on whether you want SSPM to have read-permissions only or read and write permissions.

   1. Identify the scopes that SSPM requires.

      In SSPM, the Office 365 onboarding screen lists the scopes that SSPM requires. To get the required scopes, you will begin the onboarding process in SSPM, but you will not complete the process.

         Don’t continue to the next step unless you have copied the permissions. Later, you will add these permissions to your application.
      4. Because you won't be completing the onboarding process until after you have finished configuring your application, Cancel Onboarding.

   9. On the API permissions page, verify that all the scopes were added as application permissions.

      The scopes you added should all have a type of Application. Only the User.Read permission, which Microsoft Entra added automatically when you registered the application, will have a type of Delegated.
   10. On the API permissions page, select Grant admin consent for your organization.
4. Copy the application credentials (client ID and client secret) for your application.

   1. Copy the client ID.

      1. From the details page for your application, select Overview.
