Defender's defaults left behavior monitoring off and every setting
unmanaged. Ship /etc/opt/microsoft/mdatp/managed/mdatp_managed.json:
real-time protection, behavior monitoring, PUA blocking, cloud-delivered
protection at the high block level, automatic definition updates and
sample submission, and scheduled scans (daily quick at 12:00, weekly full
on Wednesday 12:30, low priority). Users can't change managed settings.
The build fails if the file isn't valid JSON.
Network protection (Insiders channels only) and tamper protection
(audit-only preview on Linux) are left out.
The compliance script and rules now also check behavior monitoring and
cloud-delivered protection.
