Encryption

There are two basic kinds of encryption available for Azure Storage: encryption at rest and client-side encryption.

1. Encryption at rest

Azure Storage encryption protects and safeguards your data to meet your organizational security and compliance commitments. Azure Storage automatically encrypts all data prior to persisting to the storage account and decrypts it prior to retrieval. The encryption, decryption, and key management processes are transparent to users. Customers can also choose to manage their own keys using Azure Key Vault.

2. Client-side encryption

The Azure Storage client libraries provide methods for encrypting data from the client library before sending it across the wire and decrypting the response. Data encrypted via client-side encryption is also encrypted at rest by Azure Storage.

Azure NetApp Files data traffic is inherently secure by design, as it doesn't provide a public endpoint and data traffic stays within customer-owned VNet. Data-in-flight isn't encrypted by default. However, data traffic from an Azure VM (running an Network File System or Server Message Block client) to Azure NetApp Files is as secure as any other Azure-VM-to-VM traffic. NFSv4.1 and SMB3 data-in-flight encryption can optionally be enabled.

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...
