### What happens when an integrity fault is detected?

Microsoft Defender for Cloud periodically performs attestation. If the attestation fails, a medium severity alert is triggered. Trusted launch attestation can fail for the following reasons:
155157
- The attested information, which includes a log of the Trusted Computing Base (TCB), deviates from a trusted baseline (like when Secure Boot is enabled). This can indicate that untrusted modules have been loaded and the OS may be compromised.
156158
- The attestation quote could not be verified to originate from the vTPM of the attested VM. This can indicate that malware is present and may be intercepting traffic to the TPM.
157159
- The attestation extension on the VM is not responding. This can indicate a denial-of-service attack by malware, or an OS admin.

### How does trusted launch compare to Hyper-V Shielded VM?
160162

161-
Hyper-V Shielded VM is currently available on Hyper-V only. [Hyper-V Shielded VM](/windows-server/security/guarded-fabric-shielded-vm/guarded-fabric-and-shielded-vms) is typically deployed in conjunction with Guarded Fabric. A Guarded Fabric consists of a Host Guardian Service (HGS), one or more guarded hosts, and a set of Shielded VMs. Hyper-V Shielded VMs are intended for use in fabrics where the data and state of the virtual machine must be protected from both fabric administrators and untrusted software that might be running on the Hyper-V hosts. Trusted launch on the other hand can be deployed as a standalone virtual machine or virtual machine scale sets on Azure without additional deployment and management of HGS. All of the trusted launch features can be enabled with a simple change in deployment code or a checkbox on the Azure portal.

The response will be similar to the following form. `TrustedLaunchDisabled True` in the output indicates that the Generation 2 VM size does not support Trusted launch. If it's a Generation 2 VM size and `TrustedLaunchDisabled` is not part of the output, it implies that Trusted launch is supported for that VM size.
