This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Azure Spring Apps. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Azure Spring Apps.
You can monitor this security baseline and its recommendations using Microsoft Defender for Cloud. Azure Policy definitions will be listed in the Regulatory Compliance section of the Microsoft Defender for Cloud portal page.
When a feature has relevant Azure Policy Definitions, they are listed in this baseline to help you measure compliance with the Microsoft cloud security benchmark controls and recommendations. Some recommendations may require a paid Microsoft Defender plan to enable certain security scenarios.
Напомена
Features not applicable to Azure Spring Apps have been excluded. To see how Azure Spring Apps completely maps to the Microsoft cloud security benchmark, see the full Azure Spring Apps security baseline mapping file.
