We will learn about those modes in the next section of this chapter. This new server OS provides the latest benefits from Microsoft for companies in need of … The idea behind shielded VMs is quite simple. With Windows Server… However, there are folks who are running shielded VMs within a Windows Server … Linux Virtual Machines will support as a Shielded Virtual Machine with this release of Windows Server 2019 Preview and Microsoft is extending the VMConnect to improve the troubleshooting capabilities. HGS is critical to making a guarded fabric work. Windows Server 2019 also includes the ability to encrypt network segments. Furthermore, nothing is logged with these actions and the tenant will have no way of knowing that I am doing this. If your day job doesn’t include work with Hyper-V, it’s possible that you have never heard of shielded VMs. There are a couple of important pieces in this puzzle that you need to be aware of if you are interested in running shielded VMs. A 64-bit processor with second-level address translation (SLAT). While TPM 2.0 is not a firm requirement, it is certainly recommended. HGS is a service that runs on a server, or more commonly a cluster of three servers, and handles the attestation of guarded hosts. In Windows Server 2016 Hyper-V, Microsoft introduced the concept of a shielded VM for Windows OS based virtual machines. Commonly known as admin-trusted attestation, this was a very simple (and not very secure) way for your hosts to attest to HGS that they were approved. With Windows Server 2019, Microsoft is adding resiliency and redundancy enhancements to the Shielded Virtual Machines security controls it introduced with Windows Server 2016. In this article. Now, let’s have a little fun and turn into a villain. They will host VMs like any other Hyper-V Server, but they are specially crafted and configured to host these encrypted shielded VMs, and to attest their own health as part of this overall security strategy. Windows Server 2019 Datacenter is the newest version of the highly virtualized software built for private and hybrid cloud environments. If someone has access to the Hyper-V host server and opens up Hyper-V Manager, they will generally have the ability to use the Connect function on the tenant VMs in order to view whatever was currently on the console. If you are hosting a private cloud and are allowing various companies or divisions of a company to have segregated VMs running in the same fabric, you would want to ensure those divisions had real security layers between the VMs, and between the VMs and the host. What if you need to use the Hyper-V Console to figure out why a VM won’t boot or something like that?

You will need to run one or more guarded host servers in order to house your shielded VMs. Windows … However, it's not required to install Hyper-V management tools like Virtual Machine Connection (VMConnect), Hyper-V Manager, and the Hyper-V cmdlets for Windows PowerShell. Create and configure a shielded VM in Hyper-V 1 In just a few easy steps, including installing a Host Guardian Service server and creating certificates, you can shield a Hyper-V VM to protect it against … I simply right-click on that VHD and select Mount: Now that the VHD has been mounted to the host server’s operating system directly, I can browse that VM’s hard drive as if it were one of my own drives. Rather, the hard drive file itself (the VHDX) is encrypted, using BitLocker. 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. Windows Server 2019 was released earlier this year and, with it, there are a number of new features to be considered. Windows Server 2019 provides shielded support for mixed OS environments. This can be helpful if HGS is offline (although HGS being completely offline probably means that you have big problems), but HGS cache has a more valid use case in branch-office scenarios where a guarded host might have poor network connection to HGS. When your guarded host servers are equipped with TPM 2.0 chips, this opens the door to do some incredibly powerful host attestation. TPM chips are physical chips installed on your server’s motherboards that contain unique information. This example cuts to the core of why so many companies are scared to take that initial step into cloud hosting—there is an unknown level of security for those environments. I also want to point out a capability related to HGS that is brand new in Windows Server 2019: HGS cache. Regardless of the Hyper-V features you want to use, you'll need: 1. If your environment is new and based on Server 2019, don’t pay any attention to this one. 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 … New in Server 2019 is HGS cache for VM keys so that a guarded host is able to start up approved VMs based on keys in the cache, rather than always having to check in with a live HGS. Download the Windows Server 2019 licensing datasheet Move Windows Server licences to Azure and save up to 40%. It is their job to host your VMs. There are different requirements for HGS, depending on what attestation mode your guarded hosts are going to utilize. Windows Server 2019 helps to ensure that all apps and system components have just enough access privilege. To install the Hyper-V virtualization components such as Windows hypervisor, the processor must have SLAT. Attestation of the guarded hosts is the secret to using shielded VMs. Thankfully, Microsoft is taking steps to alleviate this security loophole with a new technology called shielded VMs. Ensure that you have installed the latest cumulative update before you deploy shielded virtual machines in production. New in Server 2019 is HGS cache for VM keys so that a guarded host is able to start up approved VMs based on keys in the cache, rather than always having to check in with a live HGS. It would be easy for me to kill off that WEB3 server completely, since I have access to the host administrative console. Microsoft states that the Shielded VMs concept in Windows Server 2016 was well received by customers, so in Windows Server 2019, Microsoft has extended the Shielded Virtual Machine concept to encompass Linux Virtual Machines. Windows Server 2019 – Why move to PowerShell? This not only boosts performance efficiency in the virtual machines but also keeps the physical server safe. Download the Windows Server 2019 licensing datasheet Move Windows Server licenses to Azure and save up to 40 percent. Discover and address security breaches with assistance from the integrated Windows Defender Advanced Threat Protection1. Windows Admin Center is a locally deployed, browser-based app for managing servers, clusters, hyper-converged infrastructure, and Windows 10 PCs. You also wouldn’t want any other tenants who might have VMs running on the same cloud host to be able to see your servers in any way. As is often the case with everything in the IT world, we are trading usability for security. It is possible to run Linux containers … This is the basis of security in wanting to move forward with such a solution in your own environment. When a shielded VM attempts to start on a guarded host server, that host must reach over to HGS and attest that it is safe and secure. Videos, blog, and overview topic about guarded fabrics and shielded VMs. More than likely, this would leave them staring at a login screen that they, hopefully, would not be able to breach. Shielded VMs make the security of your VMs much higher. You, as a tenant, certainly wouldn’t want your cloud provider to be able to snoop around inside your virtual machines that are being hosted in that cloud. However, there are folks who are running shielded VMs within a Windows Server 2016 infrastructure, and in that case, there was an additional option for attestation. Admin-trusted attestation – deprecated in 2019 If your environment is new and based on Server 2019, don’t pay any attention to this one. So when you create a shielded VM, it not only encrypts the VHD using BitLocker technology, it also blocks all access to the VM’s console from Hyper-V Manager. Hybrid Cloud. Guarded hosts are essentially Hyper-V servers on steroids. If you are configuring new Hyper-V Servers, make sure they contain TPM 2.0 chips so that you can utilize these features.

Microsoft already has a great drive-encryption technology, called BitLocker. It sounds simple, but there are some decent requirements for making this happen. Software-defined storage. Navigate to the wwwroot folder in order to find the website files, and change the default page to display whatever you want: When I’m finished playing around with the website, I can open up Disk Management, right-click on that mounted disk, and select Detach VHD to cover my tracks: And then, just for the fun of it, I copy the entire VHD file onto a USB so that I can take it with me and mess around with it more later. Which is best? If you have ever installed Hyper-V role on Windows Server 2012 R2 or 2016, the requirements are almost the same. Also, it is a fact that this WEB3 server is joined to my tenant’s domain and network, and I as the cloud host have absolutely no access to domain credentials, or any other means that I can utilize to actually log in to that server. While this in itself isn’t as big a deal as drive encryption, it’s still important enough to point out. Chips so that you can utilize these features I don ’ t need any credentials...
