Abstract
Example methods are provided to use a guest monitoring mode (GMM) module in a hypervisor to authenticate hypercalls sent by a guest agent to the GMM module. The GMM module uses reference information, including thread information associated with a thread, to determine whether a hypercall associated with the thread was issued by the trusted guest agent or by potentially malicious code.
