在 Windows 10 中启用或禁用 Credential Guard

Enable or Disable Credential Guard in Windows 10: Windows Credential Guard uses virtualization-based security to isolate secrets so that only privileged system software can access them. Unauthorized access to these secrets can lead to credential theft attacks, such as Pass-the-Hash or Pass-The-Ticket. Windows Credential Guard prevents these attacks by protecting NTLM password hashes, Kerberos Ticket Granting Tickets, and credentials stored by applications as domain credentials.

By enabling Windows Credential Guard the following features and solutions are provided:

硬件安全
