On top of that you could have security guards in front of the datacenter. It’s ok. With virtual machines, we’ve taken an operating system, an application and its dependencies which used to run on hardware and encapsulated those into a few files for a virtual machine so we can run multiple virtual machines (if not dozens) on a single system concurrently. Shielded VMs, or Shielded Virtual Machines, are a security feature introduced in Windows Server 2016 for protecting Hyper-V Generation 2 virtual machines (VMs) from unauthorized access or tampering by using a combination of techniques like Secure boot, Bit-locker encryption, virtual Trusted Platform Module and the Host Guardian Service. Shielded VMs help protect your virtual machines against rootkits and boot- and kernel-level malware with secure and measured boot capabilities. In my case, the Guarded Host is a fresh and clean install, so I will scan the whole system. You can join this server to an existing AD Domain, but the best practice is to create a new one: The machine will reboot. The IP Address is 10.0.0.6 2. Microsoft this week talked more about its Shielded Virtual Machines datacenter security technology. https://docs.microsoft.com/en-us/windows-server/security/set-up-hgs-for-always-encrypted-in-sql-server#set-up-the-first-hgs-node In order to run a shielded VM you need the HGS role installed. Shielded Virtual Machines will need to be encrypted by Bitlocker (or other solutions) in order to ensure that only the designated owners can run this virtual machine. The reason why Hyper-V presents such a huge risk has to do with Hyper-V anatomy. Worse, they can take those virtual machines home and run them on their personal desktop or laptop and you still have no idea they left the premises. Nested Virtualization. Install Server Migration Tool. In my point of view, Shielded VMs are not very well documented. This command will create the XML file that you will convert into a Device Guard Policy using the the ConvertFrom-CIPolicy cmdlet: Note: If this cmdlet cannot generate a rule at the specified level, in my case at the FilePublisher level, then this cmdlet attempts to generate it at a fallback level (in my case at the hash level). You can set up an Active Directory trust and a group in which these machines can register, and then you can add Hyper-V host machines to that group to gain permission to run shielded VMs. Finally, a huge thanks to all of you for your feedback on Windows Server 2016.
