Azure Machine Learning workspaces should use customer-managed keys for encryption
Manage encryption at rest of Azure Machine Learning workspace data with customer-managed keys. By default, customer data is encrypted with service-managed keys. Customer-managed keys enable the data to be encrypted with an Azure Key Vault key created and owned by you.
Customer-managed keys are commonly required to meet regulatory compliance standards. Customer-managed keys enable the data to be encrypted with an Azure Key Vault key created and owned by you. You have full control and responsibility for the key lifecycle, including rotation and management.
What this control checks
Azure Machine Learning workspaces should use customer-managed keys for encryption
Common pitfalls
Workspaces of kind project are skipped
The policy rule skips resources where kind equals project.
