  • Domain separation is supported for this application. The Microsoft Graph Security API integration ingests alerts from Microsoft Graph security providers and automatically creates security incidents. Domain separation enables you to separate data, processes, and administrative tasks into logical groupings called domains. You can control several aspects of this separation, including which users can see and access data.

    Support level: Basic

    • Business logic: Ensure that data goes into the proper domain for the application’s service provider use cases.
    • The application supports domain separation at run time. The domain separation includes separation from the user interface, cache keys, reporting, rollups, and aggregations.
    • The owner of the instance must set up the application to function across multiple tenants.

    Sample use case: When a service provider (SP) uses chat to respond to a tenant-customer’s message, the customer must be able to see the SP's response.

    How domain separation works in the Microsoft Graph Security API

    To achieve domain separation, replicate the Microsoft Graph Security API Profile Process and SIR Process Alert Updates scheduled jobs and change the Run as users. By default, the system users execute these scheduled jobs. Change the Run as to a user with the sn_si.admin role in the respective domain and run the scheduled job.
