Ensure that Azure Storage Accounts have infrastructure encryption enabled.
Azure Storage automatically encrypts all data in a storage account at the service level using 256-bit AES encryption. But customers who require higher levels of assurance that their data is secure can also enable 256-bit AES encryption at the Azure Storage infrastructure level for double encryption. Double encryption of Azure Storage data protects against a scenario where one of the encryption algorithms or keys may be compromised. In this scenario, the additional layer of encryption continues to protect your data.
Delete storage account and create new storage account with infrastructure encryption enabled.
