Details of the Azure 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 Azure Security Benchmark. For more information about this compliance standard, see Azure Security Benchmark. To understand Ownership, see Azure Policy policy definition and Shared responsibility in the cloud.

The following mappings are to the Azure Security Benchmark controls. Use the navigation on the right to jump directly to a specific compliance domain. 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 Azure 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.
