Azure HDInsight clusters should use customer-managed keys to encrypt data at rest
Use customer-managed keys to manage the encryption at rest of Azure HDInsight clusters. By default, customer data is encrypted with service-managed keys. Customer-managed keys use an Azure Key Vault key created and owned by you.
By default, customer data is encrypted with service-managed keys, but customer-managed keys are commonly required to meet regulatory compliance standards. You have full control and responsibility for the key lifecycle, including rotation and management.
What this control checks
Whether the cluster's at-rest encryption is set up to use a customer-managed key
Common pitfalls
Default encryption uses service-managed keys
By default, customer data is encrypted with service-managed keys.
