Security

Feature Description
Windows Defender System Guard Windows Defender System Guard Secure Launch protects bootup with a technology known as the Dynamic Root of Trust for Measurement (DRTM). With DRTM, the system initially follows the normal UEFI Secure Boot process. However, before launching, the system enters a hardware-controlled trusted state that forces the CPU(s) down a hardware-secured code path. If a malware rootkit/bootkit has bypassed UEFI Secure Boot and resides in memory, DRTM will prevent it from accessing secrets and critical code protected by the virtualization-based security environment. Firmware Attack Surface Reduction technology can be used instead of DRTM on supporting devices such as Microsoft Surface. For more information, see How a hardware-based root of trust helps protect Windows.
Windows Defender Security Center Improvements now include Protection history, including detailed and easier to understand information about threats and available actions, Controlled Folder Access blocks are now in the Protection history, Windows Defender Offline Scanning tool actions, and any pending recommendations. For more information, see Windows Defender Security Center.

In this release, Windows Defender Firewall is also easier to analyze and debug using an in-box cross-component network diagnostic tool for Windows. Additionally, event logs have been enhanced to ensure an audit can identify the specific filter that was responsible for any given event. For more information, see Windows Defender Firewall
