### Impact

This policy identifies blob containers within an Azure storage account that allow anonymous/public access ('CONTAINER' or 'BLOB'). As a best practice, do not allow anonymous/public access to blob containers unless you have a very good reason. Instead, you should consider using a shared access signature token for providing controlled and time-limited access to blob containers. 'Public access level' allows you to grant anonymous/public read access to a container and the blobs within Azure blob storage. By doing so, you can grant read-only access to these resources without sharing your account key, and without requiring a shared access signature.

### How to Fix

*Resource:*

* azurerm\_storage\_account

*Arguments:*

* allow\_nested\_items\_to\_be\_public \[source,go]

***

resource "azurerm\_storage\_account" "example" { name = "examplestoracc" resource\_group\_name = azurerm\_resource\_group.example.name location = azurerm\_resource\_group.example.location account\_tier = "Standard" account\_replication\_type = "LRS"

## ... other configurations ...

* allow\_nested\_items\_to\_be\_public = false

## ... other configurations ...

### }

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/public-exposure/appsec-azure-190.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
