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.
