      Queue Service All Access ACL

      Risk Level: High

      Description 

      This plugin ensures queues do not allow full write, delete, or read ACL permissions. Queues can be configured to allow objects to read, write or delete. This option should not be configured unless there is a strong business requirement.

      About the Service

      Storage Accounts: An azure storage account is used to store the customer’s data objects such as files, queues, shares, etc. The storage accounts ensure high availability for the clients and allot a unique namespace for the storage data and are accessible from anywhere around the world using HTTP or HTTPS protocols.

      Impact  

      Providing public access to storage accounts will hamper the system’s confidentiality and raise privacy concerns. Thus, it is suggested that users change the access level from all to selected networks and ensure that only authorized people get hold of the contents.
