Details of the CMMC Level 3 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 CMMC Level 3. For more information about this compliance standard, see CMMC Level 3. To understand Ownership, see Azure Policy policy definition and Shared responsibility in the cloud.

The following mappings are to the CMMC Level 3 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 CMMC Level 3 Regulatory Compliance built-in initiative definition.

This built-in initiative is deployed as part of the CMMC Level 3 blueprint sample.

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.

Access Control

Limit information system access to authorized users, processes acting on behalf of authorized users, and devices (including other information systems).
