For example, the following image shows that the user added now has read permissions to data in the container named sample-container. This will act as a transit gateway for ingress into your Azure VNET and target Storage Container (BLOB). Before you assign an Azure role to a security principal, determine the scope of access that the security principal should have. Azure provides the following Azure built-in roles for authorizing access to blob and queue data using Azure AD and OAuth: Only roles explicitly defined for data access permit a security principal to access blob or queue data. For more information, see Access control in Azure Data Lake Storage Gen2. File again try again drop hold down control new file..... if to rename..... (Keyboard typing) we just make really simple quick example again Rename the class, for shared access signatures as we expect we generate the client enter before.... the contents here or the method (keyboard typing) and deleting the contents of the method also rename the method and this is for obtaining a shared access signature token. Result: After you completed this exercise, you have created a blob container, uploaded a file into it, and tested access control by using a SAS token and a stored access policy.. We set the properties in there. Environment setup for the sample From the overview page of your AAD Application, note down the CLIENT IDand TENANT ID. Nope, they still haven't added this. - [Instructor] Now we want to look at access control. WARNING: Your account's Shared Key does not have detailed access control. SAS token here will be static string versus token read created during class initialization available as long as these tests within this class is running and so down here, a test for zero SAS I should be able to use SAS token to gain access to the blob. [!TIP] There are more .NET code samples available in Azure Blob Storage Samples for .NET.. From the above, we have access tokens for storage account (coarse grain), container, and blob (fine grain).

Azure Blob Storage is used to store arbitrary unstructured data like images, files, backups, etc. Built-in roles such as Owner, Contributor, and Storage Account Contributor permit a security principal to manage a storage account, but do not provide access to the blob or queue data within that account via Azure AD. Access can be scoped to the level of the subscription, the resource group, the storage account, or an individual container or queue. The Reader role is an Azure Resource Manager role that permits users to view storage account resources, but not modify them. It works by having AAD (Azure Active Directory) authorize requests to secured resources based on roles.
