What is Azure Policy Guest Configuration, and how does it help in ensuring compliance for virtual machines? Azure Policy Guest Configuration is a service in Microsoft Azure that helps organizations enforce compliance for virtual machines (VMs) and other resources running in Azure. It allows you to define and enforce specific configuration settings and policies on VMs to ensure they adhere to security and compliance standards. Azure Policy Guest Configuration is particularly useful for maintaining a secure and compliant infrastructure by continuously assessing and remediating configuration drifts and vulnerabilities on VMs.
