Azure Arc-enabled SCVMM: Securing the Azure Connected Machine agent during onboarding with PowerShell

This article addresses the overlooked aspect of securing the Azure Connected Machine agent when deploying Azure Arc-enabled SCVMM. It explains that default onboarding via Azure portal, PowerShell, or CLI leaves management and security controls unconfigured. The post provides a PowerShell script that combines guest management enablement with hardening steps, such as extension allowlisting and inbound connection restrictions. Prerequisites include Azure subscription, required PowerShell modules, RBAC permissions, and WinRM access. The script ensures the agent is deployed with enhanced security from the start, closing a common gap in documentation.
