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. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
