# Blob Containers anonymous access should be restricted
 
## Description{% #description %}

Ensures that Azure Storage Blob Containers are not publicly accessible.

## Rationale{% #rationale %}

Anonymous access to Azure storage blob containers allows unauthenticated users to perform operations against the blob container. Datadog recommends only allowing authenticated users access to storage blobs.

## Remediation{% #remediation %}

Datadog recommends both making the Blob Container private, and blocking public access at the storage account level.
