Details of the Microsoft cloud security benchmark Regulatory Compliance built-in initiative
The following article details how the Azure Policy Regulatory Compliance built-in initiative definition maps to compliance domains and controls in Microsoft cloud security benchmark. For more information about this compliance standard, see Microsoft cloud security benchmark. To understand Ownership, review the policy type and Shared responsibility in the cloud.
The following mappings are to the Microsoft cloud security benchmark controls. Many of the controls are implemented with an Azure Policy initiative definition. To review the complete initiative definition, open Policy in the Azure portal and select the Definitions page. Then, find and select the Microsoft cloud security benchmark Regulatory Compliance built-in initiative definition.
Important
Each control below is associated with one or more Azure Policy definitions. These policies may help you assess compliance with the control; however, there often is not a one-to-one or complete match between a control and one or more policies. As such, Compliant in Azure Policy refers only to the policy definitions themselves; this doesn't ensure you're fully compliant with all requirements of a control. In addition, the compliance standard includes controls that aren't addressed by any Azure Policy definitions at this time. Therefore, compliance in Azure Policy is only a partial view of your overall compliance status. The associations between compliance domains, controls, and Azure Policy definitions for this compliance standard may change over time. To view the change history, see the GitHub Commit History.

Description | Effect(s) | Version (GitHub) |
|---|---|---|---|
| Azure AI Services resources should encrypt data at rest with a customer-managed key (CMK) | Using customer-managed keys to encrypt data at rest provides more control over the key lifecycle, including rotation and management. This is particularly relevant for organizations with related compliance requirements. This is not assessed by default and should only be applied when required by compliance or restrictive policy requirements. If not enabled, the data will be encrypted using platform-managed keys. To implement this, update the 'Effect' parameter in the Security Policy for the applicable scope. | Audit, Deny, Disabled | 2.2.0 |
| Azure Cosmos DB accounts should use customer-managed keys to encrypt data at rest | Use customer-managed keys to manage the encryption at rest of your Azure Cosmos DB. By default, the data is encrypted at rest with service-managed keys, but 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.

Learn more about private links at: https://docs.azure.cn/key-vault/general/private-link-service. | [parameters('audit_effect')] | 1.2.1 |
| Key vaults should have deletion protection enabled | Malicious deletion of a key vault can lead to permanent data loss. You can prevent permanent data loss by enabling purge protection and soft delete. Purge protection protects you from insider attacks by enforcing a mandatory retention period for soft deleted key vaults.
