## What you need to know

DSE recommends reviewing the data-access code and storage context separately from the operator’s Azure sign-in.

## Potentially affected

This applies when a team adapts Microsoft’s AzTable PowerShell examples and needs to establish the actual authorization mechanism used for table data operations.

## DSE recommendation

DSE recommends reviewing the data-access code and storage context separately from the operator’s Azure sign-in.

## Article

## Source facts

Microsoft states that the AzTable module supports Shared Key authorization and its examples use the storage account access key. The module does not natively support Microsoft Entra authorization; that approach requires calling .NET client-library methods from PowerShell. For AzTable entity operations, the guide requires the table’s CloudTable property. [Microsoft Learn](https://learn.microsoft.com/en-us/azure/storage/tables/table-storage-how-to-use-powershell)

## Applicability

This applies when a team adapts Microsoft’s AzTable PowerShell examples and needs to establish the actual authorization mechanism used for table data operations.

## DSE recommendation

DSE recommends reviewing the data-access code and storage context separately from the operator’s Azure sign-in. Record which module or client library performs the entity operation and how that client receives authorization. If the requirement is Microsoft Entra access, choose the documented client-library path and validate it explicitly. Keep account-key handling out of ordinary logs and review any copied sample cleanup commands before using an existing resource group.

## Verification

Run an approved read against a test table using the intended client and identity. Capture the authorization configuration and operation result without recording secrets. Confirm that the code path meets the stated identity requirement rather than accepting a successful management-plane login as proof. Resolve any unexpected Shared Key dependency before handing over the script.
