ABSTRACT:
A computer includes a virtual machine controlled by a hypervisor. The virtual machine runs a virtualized operating system with running processes. A security initialization module sets the state in the virtual machine to pass execution from the virtual machine to the hypervisor responsive to a process making a system call in the virtualized operating system. Responsive to execution being passed from the virtual machine to the hypervisor, a security module analyzes the process making the system call to determine whether it poses a security threat. If a security threat is found, the security module takes remedial action to address the threat.
