As per the requirements, I need to Enable Firewall with Selected Network ON for Azure Storage Accounts. But when I do the same along with adding all required IPs, Azure Function App and Azure Data Factory is going down.
Currently the VNET is unavailable and cannot be created. Managed Identity is not an option as Contributor role unavailable.
Is there a way to to configure the Data Factory and Function Apps after enabling FireWall with selected networks for Azure KeyVault and Azure Storage Accounts.
Please find the below steps helps to work around:
Is there a way to to configure the Data Factory and Function Apps after enabling FireWall with selected networks for Azure KeyVault and Azure Storage Accounts.
When Network rules like specified IP Addresses, IP Ranges, subnets are configured to the storage accounts, then that storage accounts can only be accessed by applications that request data over the specified set of networks or through the specified set of Azure resources.
Also, the option Allow Trusted Services is set to ON while enabling the firewall for a storage account, which allows connectivity from Azure trusted services like Data Factory, Azure functions, etc.
Visit this documentation to know the list of trusted services allowed to access a key vault in Azure.
You have to create the VNet, attach to the Azure Function App which helps to connect to the Storage Account.
Currently the VNET is unavailable and cannot be created. Managed Identity is not an option as Contributor role unavailable.
To enable a service endpoint for a subnet/IP Addresses attached to Storage account, you can have custom role like Microsoft.Network/virtualNetworks/subnets/joinViaServiceEndpoint/action.
Refer to MSFT Docs1 and here for more information.

I'm nearly done migrating our cloud service (classic) deployments to cloud service (extended support). I'm working now on updating deployment pipelines. My package blob is located in a storage account. I create a SAS for the blob and use an API call to management.azure.com to create/update the deployment, passing ARM template as the body of the request.
This works correctly as long as the storage account with the package blob has its network set to "allow access from all networks". I want to restrict this access. I set the allow access from:
specific IP addresses of our devops servers
our own IP addresses
private vnet/subnets for the cloud service
I also tick the "Allow Azure services on the trusted services list to access this storage account" checkbox.
Yet, API call fails with error message indicating access is not allowed to the blob. When I change the storage account network configuration to "allow access from all networks", everything works correctly.
With lots of searches, I found only one hit explaining the same problem - https://github.com/Azure/azure-powershell/issues/20299 - yet no solution has been suggested other than allowing access from all networks.
I must be missing some trick - but what is it? How can I restrict access to the storage account?
I'm building a data-architecture with Azure Synapse and an ADLS2 data lake/storage account. If I want to create a Linked service that moves data from the storage account to the serverless/dedicated SQL-pool I have several options.
In my storage account, I can "enable access from all networks" so that the Integration Runtime in my synapse workspace is free to bypass the Storage account firewall. For obvious reasons this is not ideal.
I can create my Synapse workspace with "Managed virtual network" option enabled - and create a managed private endpoint between the two services.
However, I'm wondering whether it's also possible (Like it is in other Azure services) to add my Synapse workspace to an already existing virtual network, and use private endpoints to connect the services instead of managed private endpoints? I.e. connecting the services through "non-managed" private endpoints? When I browse the documentation it seems impossible;
When you create a Synapse workspace, you can choose to enable a
Managed virtual network to be associated with it. If you do not enable
Managed virtual network for your workspace when you create it, your
workspace is in a shared virtual network along with other Synapse
workspaces that do not have a Managed virtual network associated with
it. If you enabled Managed virtual network when you created the
workspace, then your workspace is associated with a dedicated virtual
network managed by Azure Synapse. These virtual networks are not
created in your customer subscription. Therefore, you will not be able
to grant traffic from these virtual networks access to your secured
storage account using network rules described above.
Any idea as to why Synapse was created as such? Is there any way to bypass this limitation?
we have a blob container with anonymous access (open to internet) and an appservice talking to it.
What are our options of ensuring that only the appservice can talk to this storage endpoint? vnet integration is our last option.
Thanks -nen

this storage endpoint?
One option would be to make use of Azure Role Based Access Control (RBAC) Data roles.
For this, first you would assign a managed identity to your App Service and then assign that identity appropriate Azure Storage RBAC data roles.
You would also need to block access to the storage account via access keys or shared access signature so that only your App Service can connect to your storage account using Azure AD authorization.
You can read more about it here: https://learn.microsoft.com/en-us/azure/storage/blobs/assign-azure-role-data-access?tabs=portal.
I have a App Service with a managed identity assigned to it to simplify connections to azure resources. I want to use DataProtection where the app stores the xml-keys in an Azure Storage Account(blob) to persist them between deploys.
Whenever I start the app I get a authentication error:
Microsoft.Azure.Storage.StorageException: This request is not authorized to perform this operation.
at Microsoft.Azure.Storage.Core.Executor.Executor.ExecuteAsync[T](RESTCommand`1 cmd, IRetryPolicy policy, OperationContext operationContext, CancellationToken token)
at Microsoft.Azure.Storage.Core.Executor.Executor.<>c__DisplayClass0_0`1.<ExecuteSync>b__0()
at Microsoft.Azure.Storage.Core.Util.CommonUtility.RunWithoutSynchronizationContext[T](Func`1 actionToRun)
I have assigned several different RBAC roles to the App Service without any succes, including:
Storage Data Owner
Storage Data Contributor
Storage Data Reader
Owner
The Storage Account is connected to a VNET and not open to the internet. THe App service is not connected to the same VNET.
I have then tried to whitelist the App services many outgoing IP-adresses in the Storage Accounts Network-section, which states "Add IP ranges to allow access from the internet or your on-premises networks."
Also have "Allow Azure services on the trusted services list to access this storage account" activated.
Any ideas whats missing? This is happening only when in the app service, from my debug-localhost I can connect, so seems related to azure networking somehow.
According to the description in your post, I can be pretty sure that your identity configuration in the portal is correct, and your code is also completely correct.
The only problem is that your app services cannot access vnet. The simple description is that the azure storage account is connected to the vnet, which is equivalent to being isolated by the vnet protection. The app service needs to access the storage account, and it must first connect to the vnet.
I am reading files on an Azure Blob Storage account (gen 2) from an Azure Databricks Notebook. Both services are in the same region (West Europe). Everything works fine, except when I add a firewall in front of the storage account. I have opted to allow "trusted Microsoft services":
However, running the notebook now ends up with an access denied error:
com.microsoft.azure.storage.StorageException: This request is not authorized to perform this operation.
I tried to access the storage directly from Spark and by mounting it with dbutils, but same thing.
I would have assumed that Azure Databricks counts as a trusted Microsoft service? Furthermore I couldn't find solid information on IP ranges for Databricks regions that could be added to the firewall rules.
Yes, the Azure Databricks does not count as a trusted Microsoft service, you could see the supported trusted Microsoft services with the storage account firewall.
From networking, Here are two suggestions:
Find the Azure datacenter IP address (Original deprecated URL) and scope a region where your Azure Databricks located. Whitelist the IP list in the storage account firewall.
Deploy Azure Databricks in your Azure Virtual Network (Preview) then whitelist the VNet address range in the firewall of the storage account. You could refer to configure Azure Storage firewalls and virtual networks. Also, you have NSG to restrict inbound and outbound traffics from this Azure VNet. Note: you need to deploy Azure Databricks to your own VNet.
Hope this helps.
The described scenario only works if you deploy Azure Databricks in your own Azure Virtual Network (vnet). With this you are able to use Service Endpoints, so could add your Databricks vnet to the Blob Storage. With the default deployment this is not supported and not possible.
See the following Documentation for more details and a description how to get the vnet-injection feature enabled.
Enabling the mentioned exception does not work, as Azure Databricks is not in the list of trusted Services for Blob Storage. See the following Documentation which services still can access the storage account with the exception enabled.
