Plan and implement remote access to public endpoints, Azure Bastion and just-in-time (JIT) virtual machine (VM) access

Key benefits


BenefitDescription
RDP and SSH through the Azure portalYou can get to the RDP and SSH session directly in the Azure portal using a single-click seamless experience.
Remote Session over TLS and firewall traversal for RDP/SSHAzure Bastion uses an HTML5 based web client that is automatically streamed to your local device. Your RDP/SSH session is over TLS on port 443. This enables the traffic to traverse firewalls more securely. Bastion supports TLS 1.2 and above. Older TLS versions aren't supported.
No Public IP address required on the Azure VMAzure Bastion opens the RDP/SSH connection to your Azure VM by using the private IP address on your VM. You don't need a public IP address on your virtual machine.
No hassle of managing Network Security Groups (NSGs)You don't need to apply any NSGs to the Azure Bastion subnet. Because Azure Bastion connects to your virtual machines over private IP, you can configure your NSGs to allow RDP/SSH from Azure Bastion only. This removes the hassle of managing NSGs each time you need to securely connect to your virtual machines.
No need to manage a separate bastion host on a VMAzure Bastion is a fully managed platform PaaS service from Azure that is hardened internally to provide you secure RDP/SSH connectivity.
Protection against port scanningYour VMs are protected against port scanning by rogue and malicious users because you don't need to expose the VMs to the internet.
Hardening in one place onlyAzure Bastion sits at the perimeter of your virtual network, so you don’t need to worry about hardening each of the VMs in your virtual network.
Protection against zero-day exploitsThe Azure platform protects against zero-day exploits by keeping the Azure Bastion hardened and always up to date for you.

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...
