As a person who has worked in this industry for over a decade, I sometimes ponder how cloud computing has made availing computing resources. This ease has resulted in the exponential growth of cloud computing. Which also makes it one of the most vulnerable platforms to host our applications. Since IaaS security and patch management has to be taken care of by the consumer, it is also easily targeted and has to be secured in the best way possible.
What is Trusted Launch?
Microsoft recently announced trusted launch offering for Generation 2 Azure Virtual machines and flexible scale sets. Trusted launch protects against advanced and persistent attack techniques with the help of several coordinated infrastructure technologies. Trusted launch can only be enabled while creating new virtual machines on the portal.
Why should you enable Trusted Launch?
- It allows the Virtual machine deployment with verified boot loaders, OS kernels and drivers.
- It also protects keys, certificates and secrets in the virtual machine with the help fo vTPM.
- Also helps gain insights and confidence of the entire boot chain’s integrity.

GitHub Link: GitHub
Powershell Script : trusted-launch.ps1
CLI Make sure you are running the latest version of Azure CLI Sign in to Azure using az login. az login Create a virtual machine with Trusted Launch. az group create -n resourceGroup -l eastus az vm create \ --resource-group ResourceGroup \ --name TrustedVM \ --image Canonical:UbuntuServer:18_04-lts-gen2:latest \ --admin-username azureuser \ --generate-ssh-keys \ --security-type TrustedLaunch \ --enable-secure-boot true \ --enable-vtpm true
For existing VMs, you can enable or disable secure boot and vTPM settings. Updating the virtual machine with secure boot and vTPM settings will trigger auto-reboot.
