Plugin Title Blob Service Encryption
Cloud AZURE
Category Storage Accounts
Description Ensures encryption is properly configured for Blob Services
More Info Blob Services can be configured to encrypt data-at-rest. By default Azure will create a set of keys to encrypt Blob Services, but the recommended approach is to create your own keys using Azure Key Vault.
AWS Link https://docs.microsoft.com/en-us/azure/storage/common/storage-service-encryption
Recommended Action Ensure that Blob Service is configured to use a customer-provided key vault key.
