Secure access to storage accounts

Every request to Azure Storage must be authorized. Azure Storage supports the following authorization methods:

  • Microsoft Entra integration for blob, file, queue, and table data. Azure Storage supports authentication and authorization with Microsoft Entra ID for the Blob, File, Table, and Queue services via Azure role-based access control (Azure RBAC). Authorizing requests with Microsoft Entra ID is recommended for superior security and ease of use.
  • Identity-based authentication over SMB for Azure Files. Azure Files supports identity-based authorization over SMB (Server Message Block) through either on-premises Microsoft Entra Domain Services, or Microsoft Entra Kerberos (hybrid user accounts only).
  • Authorization with Shared Key. The Azure Storage Blob, Files, Queue, and Table services support authorization with Shared Key. A client using Shared Key authorization passes a header with every request that is signed using the storage account access key. pended to the URI for a storage resource. The security token encapsulates constraints such as permissions and the interval of access.
  • Microsoft Entra Domain Services with Azure NetApp Files. Azure NetApp Files features such as SMB volumes, dual-protocol volumes, and NFSv4.1 Kerberos volumes are designed to be used with Microsoft Entra Domain Services.

Azure built-in roles for tables

Azure RBAC provides built-in roles for authorizing access to table data using Microsoft Entra ID and OAuth. Built-in roles that provide permissions to tables in Azure Storage include: Storage Table Data Contributor: Use to grant read/write/delete permissions to Table storage resources. Storage Table Data Reader: Use to grant read-only permissions to Table storage resources. To learn how to assign an Azure built-in role to a security principal, see Assign an Azure role for access to table data. To learn how to list Azure RBAC roles and their permissions, see List Azure role definitions. For more information about how built-in roles are defined for Azure Storage, see Understand role definitions. For information about creating Azure custom roles, see Azure custom roles. Only roles explicitly defined for data access permit a security principal to access table data. Built-in roles such as Owner, Contributor, and Storage Account Contributor permit a security principal to manage a storage acc...

Explore Dataflows Gen2 in Microsoft Fabric

  In Microsoft Fabric, you can create a Dataflow Gen2 in the Data Factory workload or Power BI workspace, or directly in the lakehouse. Since our scenario is focused on data ingestion, let's look at the  Data Factory  workload experience. Dataflows Gen2 use Power Query Online to visualize transformations.  1. Power Query ribbon Dataflows Gen2 support a wide variety of data source connectors. Common sources include cloud and on-premises relational databases, Excel or flat files, SharePoint, SalesForce, Spark, and Fabric lakehouses. Then there are numerous data transformations possible, such as: Filter and Sort rows Pivot and Unpivot Merge and Append queries Split and Conditional split Replace values and Remove duplicates Add, Rename, Reorder, or Delete columns Rank and Percentage calculator Choose Top N and Bottom N You can also create and manage data source connections, manage parameters, and configure the default data destination in this ribbon. 2. Queries pane The ...

Select and configure an appropriate method for access to Azure Blobs

Azure Storage supports using Microsoft Entra ID to authorize requests to blob data. With Microsoft Entra ID, you can use Azure role-based access control (Azure RBAC) to grant permissions to a security principal, which may be a user, group, or application service principal. The security principal is authenticated by Microsoft Entra ID to return an OAuth 2.0 token. The token can then be used to authorize a request against the Blob service. Authorization with Microsoft Entra ID is available for all general-purpose and Blob storage accounts in all public regions and national clouds. Only storage accounts created with the Azure Resource Manager deployment model support Microsoft Entra authorization. For optimal security, Microsoft recommends using Microsoft Entra ID with managed identities to authorize requests against blob, queue, and table data, whenever possible. Authorization with Microsoft Entra ID and managed identities provides superior security and ease of use over Shared Key author...
