Information
Use private endpoints for your Azure Storage accounts to allow clients and services to securely access data located over a network via an encrypted Private Link. To do this, the private endpoint uses an IP address from the VNet for each service. Network traffic between disparate services securely traverses encrypted over the VNet. This VNet can also link addressing space, extending your network and accessing resources on it. Similarly, it can be a tunnel through public networks to connect remote infrastructures together. This creates further security through segmenting network traffic and preventing outside sources from accessing it.
Rationale:
Securing traffic between services through encryption protects the data from easy interception and reading.
Impact:
There is no cost in deploying VNets between Azure resources. If improperly implemented, it may result in loss of critical network traffic.
Solution
From Azure Portal
Open the Storage Accounts blade
For each list Storage Account, perform the following:
Under the Security + networking heading, click on Networking
Click on the Private Endpoint Connections tab at the top of the networking window
Click the +Private endpoint button
In the 1 - Basics tab/step:
Enter a name that will be easily recognizable as associated with the Storage Account (Note: The 'Network Interface Name' will be automatically completed, but you can customize it if needed.)
Ensure that the Region matches the region of the Storage Account
Click Next
In the 2 - Resource tab/step:
Select the target sub-resource based on what type of storage resource is being made available
Click Next
In the 3 - Virtual Network tab/step:
Select the Virtual network that your Storage Account will be connecting to
Select the Subnet that your Storage Account will be connecting to
(Optional) Select other network settings as appropriate for your environment
Click Next
In the 4 - DNS tab/step:
(Optional) Select other DNS settings as appropriate for your environment
Click Next
In the 5 - Tags tab/step:
(Optional) Set any tags that are relevant to your organization
Click Next
In the 6 - Review + create tab/step:
A validation attempt will be made and after a few moments it should indicate Validation Passed - if it does not pass, double-check your settings before beginning more in depth troubleshooting.
If validation has passed, click Create then wait for a few minutes for the scripted deployment to complete.
Repeat the above procedure for each Private Endpoint required within every Storage Account.
Default Value:
By default, Private Endpoints are not created for Storage Accounts.
