Abstract
This disclosure addresses systems and methods for the protection of hardware and software in a computing environment. A hypervisor-monitor may be nested between the hardware of a host system and a hypervisor that is capable of supporting one or more guest virtual machines. The hypervisor-monitor may intercept exceptions generated by one or more processors in the host system and inspect software instructions for the hypervisor and the guests. Inspection may include performing a hash of the software instructions and a comparison of the hash with authorized software modules or a set of known malware. In this manner the hypervisor-monitor may monitor prevent the execution of malware by the hypervisor or the guests or provide a record of when code of an unknown origin was executed.
