what is a shielded vm

Guarded hosts are approved based on possession of the key. Virtual Secure Mode provides the system with the ability to store operating system keys that are not visible to an operating system administrator. A host can only be considered. Shielded VMs boot from a virtual Unified Extensible Firmware Interface (UEFI) as opposed to a traditional BIOS, providing Secure Boot protection and enabling BitLocker disk encryption inside the VM’s virtual disks. Both shielded VMs and encryption-supported VMs continue to support commonplace fabric management capabilities, such as Live Migration, Hyper-V replica, VM checkpoints, and so on. This blog mainly aims at calling … 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. This TPM is required to decrypt the contents of the drive. Host key attestation (based on asymmetric key pairs), A security policy that determines whether VMs created using this shielding data are configured as shielded or encryption supported, Remember, VMs configured as shielded are protected from fabric admins whereas encryption supported VMs are not, An RDP certificate to secure remote desktop communication with the VM, A volume signature catalog that contains a list of trusted, signed template-disk signatures that a new VM is allowed to be created from, A Key Protector (or KP) that defines which guarded fabrics a shielded VM is authorized to run on, A normal VM offering no protections above and beyond previous versions of Hyper-V, An encryption-supported VM whose protections can be configured by a fabric admin, A shielded VM whose protections are all switched on and cannot be disabled by a fabric admin. Shielded VMs protect virtual machines from compromised or malicious administrators in the fabric, such as storage admins, backup admins, etc. Safeguard VMs so that VMs can only run on infrastructure you designate as your organization’s fabric and are 2. THIS COMPENSATION MAY IMPACT HOW AND WHERE PRODUCTS APPEAR ON THIS SITE INCLUDING, FOR EXAMPLE, THE ORDER IN WHICH THEY APPEAR. If you decide to move to TPM-trusted attestation when you acquire new hardware, you can switch the attestation mode on the Host Guardian Service with little or no interruption to your fabric. Each VM in a shielded VM environment has its own trusted platform module (TPM) embedded in the virtual hardware. A virtualized version of a Trusted Platform Module (TPM). If for some reason a host doesn't have an attestation certificate when a VM tries to start, this also triggers attestation. Virtualization security is a major investment area in Hyper-V. The Hyper-V administrator can only turn the VM on or off. The IP Address is 10.0.0.5 3. 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. The Attestation service ensures only trusted Hyper-V hosts can run shielded VMs while the Key Protection Service provides the keys necessary to power them on and to live migrate them to other guarded hosts. Host key attestation: Hyper-V host sends the public half of the key pair. Shielded VMs and guarded fabric enable cloud service providers or enterprise private cloud administrators to provide a more secure environment for tenant VMs. A shielded VM can only run on a trusted guarded host. The main data file for the VM… A shielding data file (also called a provisioning data file or PDK file) is an encrypted file that a tenant or VM owner creates to protect important VM configuration information, such as the administrator password, RDP and other identity-related certificates, domain-join credentials, and so on.

As a result, the data and state of a Shielded VM are protected against inspection, theft and tampering from malware running on a Hyper-V host as well as the fabric admins administering it. The following table summarizes the differences between encryption-supported and shielded VMs. A trusted administrator in the public or private cloud that has the authority to manage the policies and cryptographic material for guarded hosts, that is, hosts on which a shielded VM can run.
