Using Microsoft Entra External ID for FHIR Service Access Control
Uso del identificador externo de Microsoft Entra para conceder acceso al servicio FHIR
Summary
Healthcare organizations can use the identifier from Microsoft Entra External ID with the FHIR service in Azure Health Data Services to manage secure access for their applications and users. This involves setting up an external ID tenant and deploying the FHIR service using ARM templates.
Details
This article provides a technical guide on implementing access control for the FHIR service within Azure Health Data Services, utilizing identifiers from Microsoft Entra External ID. The process begins with establishing an external ID tenant to create a secure infrastructure for managing user identities in healthcare applications. Specific implementation steps are provided using PowerShell or Azure CLI to deploy the service via ARM templates. This mechanism leverages custom attributes (e.g., fhirUser) within the Entra External ID to link users from the external identity tenant with specific patient resources within the FHIR service. This allows for strict management of which user accesses which patient data through the authentication flow, enabling secure development and operation of healthcare applications. The technology addresses Identity Management (IDM) challenges when multiple organizations or systems need to interact, ensuring high interoperability and security. The guide covers the entire workflow, from adding users to the external ID tenant to associating resources using custom attributes.
