Study Notes

Power BI Premium Security

  • Power BI Premium provides a dedicated back-end cluster in the same data center as the tenant.
  • This cluster contains roles like the Gateway Role, Data Role, and Job Processing Role, plus an Azure SQL Database.
  • All communication with the Premium cluster goes through a shared back-end cluster, routing traffic to the Gateway Role within the Premium cluster.
  • The Presentation Role (and other back-end roles) are protected from direct internet access.

Power BI Data Security

  • Power BI designers need separate credentials to connect to data sources.
  • Designer credentials are then used to access/update data, even when shared with others.
  • Designers are responsible for ensuring user access to sensitive data when sharing content.

Power BI Data Storage

  • Power BI uses Azure Blob storage for large, unstructured data (e.g., Excel imports).
  • Azure SQL Database stores other data types, including user information, workspaces, dashboards, and reports.

Data Access Methods

  • Import: Data is accessed from a file (e.g., Excel).
  • DirectQuery: Data is accessed by referencing an external source (e.g., SharePoint, database).

Data Processing

  • Imported data is read into an Analysis Services in-memory database (up to 1-hour retention, encrypted in Azure Blob).
  • DirectQuery data is stored in Analysis Services only while the process accessing it is active; when at rest, it's stored encrypted in Azure Blob or Azure SQL.

Power Apps Security

  • Power Apps uses Azure Active Directory authentication and licensing to control access to the portal and specific apps.
  • Administrators can assign Power Apps licenses, and regulate access with features like Azure tools and Intune policies.
  • Environments have built-in roles (Environment Admin, Environment Maker) for administrative tasks.
  • Developers can share apps with other Azure AD users (standard or co-owner).
  • Co-owners can edit and share, but not delete or change ownership.
  • Environments are isolated containers for apps, flows, and data; they are region-specific.
  • Data connections used by apps require appropriate user credentials.

Power Automate Security

  • Power Automate requires authentication credentials for connectors to external services.
  • User share options (co-owners, run-only users) impact credential access.
  • Co-owners have full access to existing connections, while run-only users have controlled access based on the creator's choice or themselves.
