Abstract

Disclosed systems and methods for authenticating virtual machines, upon detecting a virtual machine launch (VML) request associated with a hypervisor and an unconfirmed VM, request a VM signing (VMS) certificate from a deployment/verification cloud server. The VMS certificate is forwarded to a certificate store of the hypervisor. After an unconfirmed VM is successfully authenticated, the VMS certificate may be deleted from the hypervisor certificate store. If an alert indicating a failed authentication associated is detected, termination operations are performed to prevent the unconfirmed VM from running under the hypervisor. The termination operations may include identifying a suspect key or signature associated with the unconfirmed VM and recording the suspect key or signature in a prohibited database store, such as a UEFI Secure Boot DBX variable store. For example, a suspect key or signature may be a key used to sign the unconfirmed VM.
