Virtualization and hardware-based security

The Hardware and software-based security are hypervisors or virtual machine monitor (VMM) technologies that are utilized in the context of modern computing environments and requirements. Hypervisors function as reference monitors, providing workload isolation on an operating system instance granularity. Hardware support, such as management of memory and other system and processor resources and contact switching between protection modes, is critical to maximize overall system performance. IBM includes a power processor duplicating a certain key registers in a new hypervisor state that operate independently from their supervisor-state counterparts. Intel's secure computing platform, Lagrande Technology, consisting of a VT core to provide process isolation and special keyboard and video capabilities, to provide sealed storage and platform attestation.
