If you have some publicly available data, that access is specified at the container level. Public access to blob data is never permitted unless you take the additional step to explicitly configure the public access setting for a container. Then you need to call SetPermissions on the blob container, which will overwrite existing stored access policies, so take care if you have multiple policies. I have the following code to create the "default" policy. The policy grants access to all blobs in the given container with Read/Write permissions for 2 minutes. Also, public access level is container level. How to create a shared access signature with a stored access policy for an Azure Blob container in Azure Portal? I'm having trouble with Azure Blobs and Shared Access Signatures when they expire. If you have very firm requirements for data protection, this might justify separate containers which have different policies in place. You can get more details from Manage anonymous read access to containers and blobs You will see that in the new SAS URI, the query parameters are not all displayed any more, and that it will now show the signed identifier for the policy name. Hot Network Questions After 1.e4 e5 2.Nf3, is 2...Nf6 safer and easier to learn than Nc6? For this example we’re letting the policy expire in 10 hours and allowing clients to read, write and list blobs in the specified container. Then we will create an SAS URI for our blob using that stored access policy. By doing so, you can grant read-only access to these resources without sharing your account key, and without requiring a shared access signature. I also know how to create a stored access policy for a container in my Azure Blob. The use case I want to simplify is giving a few people access to files on the blob without the need of having to append a SAS token to the URI. However, I want to do the above using Azure Portal. Select the permissions which you want to give this specific container. I need to grant access to a blob for longer than 1 hour (7 days), so I'm using a named container policy, but unfortunately I can't seem to generate new urls once those 7 days are up. Microsoft recommends that you disallow public access to a storage account unless your scenario requires it. To adjust for possible clock time differences, the Start Time is set to 1 minute before current time, and two minutes from Current Time giving it a windows of three total minutes. A stored access policy provides additional control over service-level SAS on the server side. Find your container, select Access Policy under the settings blade, and click Add Policy. With the announcement of Azure Storage support for Azure Active Directory based access control, is it possible to serve a blob (a specific file) over a web browser just by it's URI?. I know how to generate an ad-hoc shared access signature. First, let’s create the stored access policy on the container in blob … Establishing a stored access policy serves to group shared access signatures and to provide additional restrictions for signatures that are bound by the policy. Now we’re in a position to create a Shared Access Signature (SAS) token (using our policy) that’ll give a user restricted access to the blobs in our storage account container. I also read how to create this shared access signature with stored access policies for Azure Storage using PowerShell here.
