Hello Dev, welcome to this comprehensive guide on the Host Guardian Service Server 2016. In today’s technology-driven world, data security has become a crucial aspect, especially for organizations dealing with sensitive information. The Host Guardian Service Server 2016 is one of the most reliable and secure solutions to protect data in a virtualized environment. In this article, we’ll explore HGS Server 2016 in detail, covering its benefits, features, and how to set up and use it.
What is Host Guardian Service Server 2016?
The Host Guardian Service (HGS) is a security feature that was first introduced in Windows Server 2016. It is designed to provide enhanced security for virtual machines running on Hyper-V hosts. HGS leverages the TPM (Trusted Platform Module) technology to ensure that only known and trusted virtual machines can run on a Hyper-V host. It creates a protected environment that helps prevent malicious software and other unauthorized code from running and compromising the VM’s security.
The HGS server acts as a guardian that manages the keys and certificates required to secure the virtual environment. It validates the health status of the Hyper-V host and virtual machines before granting access. HGS works in conjunction with Shielded Virtual Machines (VMs), which are encrypted and protected by the HGS server.

How Host Guardian Service Server 2016 Works
The Host Guardian Service Server 2016 works by using the following components:
Virtual Trusted Platform Module (vTPM)
The vTPM is a software-based emulation of a real TPM. It generates and stores cryptographic keys and secrets that are used to validate the health status of a Hyper-V host and its virtual machines. The vTPM is available in Windows Server 2016, and it’s required to use the Host Guardian Service Server.
Host Key Attestation
The Host Key Attestation is the process of validating the software and hardware components of a Hyper-V host. The attestation process ensures that only trusted hosts are allowed to run Shielded VMs. The attestation process is performed by the HGS server, which issues certificates to validate the host’s health status.
Shielded VMs
Shielded VMs are virtual machines that run on trusted Hyper-V hosts. Shielded VMs are encrypted and protected by the HGS server, ensuring that only the authorized users can access them. Shielded VMs are created using the Shielded VM Wizard in Hyper-V Manager. The wizard guides you through the process of creating a shielded VM and configuring the required settings.
The Role of the HGS Server
The HGS server plays a critical role in ensuring the security and integrity of the virtualized environment. It validates the health status of the Hyper-V host and virtual machines and issues certificates to allow access. The HGS server stores the keys and certificates required to secure the virtual environment, ensuring that only authorized users can access the data.
Setting Up Host Guardian Service Server 2016
Setting up the Host Guardian Service Server 2016 involves the following steps:
Step 1: Install the Host Guardian Service Role
The first step in setting up HGS is to install the Host Guardian Service role on a Windows Server 2016 machine. To install the role, follow these steps:
- Open Server Manager and click on “Add Roles and Features.”
- Select “Role-based or feature-based installation” and click “Next.”
- Select the server where you want to install the HGS role and click “Next.”
- Select “Host Guardian Service” under Server Roles and click “Next.”
- Click “Install” to start the installation process.
Step 2: Configure the HGS Server
Once the HGS role is installed, you need to configure the HGS server. To configure the server, follow these steps:
- Open PowerShell as an administrator.
- Run the following command to create a new HGS server group:
New-HgsServerGroup -Name "HGSGroup" -Guardians 2 -Threshhold 2
- Run the following command to generate a new encryption key:
New-HgsKeyProtectionCertificate -CertStoreLocation "Cert:\LocalMachine\My" -AlgorithmName "RSA_AES_256"
- Run the following command to set the HGS Key Protection certificate:
Set-HgsKeyProtectionCertificate -CertThumbprint [thumbprint]
- Run the following command to start the HGS service:
Start-Service hgs
Step 3: Configure the Hosts
After installing and configuring the HGS server, you need to configure the Hyper-V hosts to use the HGS server. To configure the hosts, follow these steps:
- Open Hyper-V Manager.
- Select the host and click “Settings.”
- Select “Shielded VMs” and click “Enable.”
- Follow the wizard to configure the required settings for shielded VMs.
