Vulnerability Discussion
Without Windows 10 systems being managed, devices could be rogue and become targets of an attacker.
Check
Verify the Windows 10 system is receiving policy from either Group Policy or an MDM with the following steps:
From a command line or PowerShell:
gpresult /R
OS Configuration: Member Workstation
If the system is not being managed by GPO, ask the administrator to indicate which MDM is managing the device.
If the Window 10 system is not receiving policy from either Group Policy or an MDM, this is a finding.
Fix
Configure the Windows 10 system to use either Group Policy or an approved MDM product to enforce STIG compliance.
