When your guarded host servers are equipped with TPM 2.0 chips, this opens the door to do some incredibly powerful host attestation. 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.. Hyper-V Shielded VMs are protected through a combination of Secure Boot, BitLocker encryption, Virtual … Windows Server 2019 makes it easier to integrate Linux. When guarded hosts want to spin up a shielded VM, they reach out to attest with HGS, and that attestation is approved or denied based on this key pair. The ability for your hosts to attest their health and identity gives you peace of mind in knowing that those hosts are not being modified or manipulated without your knowledge, and it ensures that a malicious host employee cannot copy all of your VM hard drive files onto a USB, bring them home, and boot them up. Linux. Windows Admin Center is a locally deployed, browser-based app for managing servers, clusters, hyper-converged infrastructure, and Windows 10 PCs.
