Azure_Security_Benchmark_v3.0 PV-4 Azure_Security_Benchmark_v3.0_PV-4 Microsoft cloud security benchmark PV-4 Posture and Vulnerability Management Audit and enforce secure configurations for compute resources Shared **Security Principle:** Continuously monitor and alert when there is a deviation from the defined configuration baseline in your compute resources. Enforce the desired configuration according to the baseline configuration by denying the non-compliant configuration or deploy a configuration in compute resources. **Azure Guidance:** Use Microsoft Defender for Cloud and Azure Policy guest configuration agent to regularly assess and remediate configuration deviations on your Azure compute resources, including VMs, containers, and others. In addition, you can use Azure Resource Manager templates, custom operating system images, or Azure Automation State Configuration to maintain the security configuration of the operating system. Microsoft VM templates in conjunction with Azure Automation State Configuration can assist in meeting and maintaining security requirements. Note: Azure Marketplace VM images published by Microsoft are managed and maintained by Microsoft. **Implementation and additional context:** How to implement Microsoft Defender for Cloud vulnerability assessment recommendations: https://docs.microsoft.com/azure/security-center/security-center-vulnerability-assessment-recommendations How to create an Azure virtual machine from an ARM template: https://docs.microsoft.com/azure/virtual-machines/windows/ps-template Azure Automation State Configuration overview: https://docs.microsoft.com/azure/automation/automation-dsc-overview Create a Windows virtual machine in the Azure portal: https://docs.microsoft.com/azure/virtual-machines/windows/quick-create-portal Container security in Microsoft Defender for Cloud: https://docs.microsoft.com/azure/security-center/container-security n/a link 13
