Level: 1

Ensure that the latest OS patches for all virtual machines are applied.

Windows and Linux virtual machines should be kept updated to: - Address a specific bug or flaw - Improve an OS or application’s general stability - Fix a security vulnerability

Microsoft Defender for Cloud retrieves a list of available security and critical updates from Windows Update or Windows Server Update Services (WSUS), depending on which service is configured on a Windows VM. The security center also checks for the latest updates in Linux systems. If a VM is missing a system update, the security center will recommend system updates be applied.
