    摘要： Generally, this disclosure provides systems, devices, methods and computer readable media for controlled memory view switching. The system may include a memory module comprising a shared address space between a first memory view and a second memory view. The system may also include a virtual machine monitor (VMM) to maintain a list of Controlled View Switch (CVS) descriptors. The system may further include a processor to receive a memory view switch request and to execute an instruction to save processor state information and switch from the first memory view to the second memory view, wherein the second memory view is specified by an extended page table pointer (EPTP) provided by one of the CVS descriptors.

    摘要： Technologies for hardware assisted native malware detection include a computing device. The computing device includes one or more processors with hook logic to monitor for execution of branch instructions of an application, compare the monitored branch instructions to filter criteria, and determine whether a monitored branch instruction satisfies the filter criteria. Additionally, the computing device includes a malware detector to provide the filter criteria to the hook logic, provide an address of a callback function to the hook logic to be executed in response to a determination that a monitored branch instruction satisfies the filter criteria, and analyze, in response to execution of the callback function, the monitored branch instruction to determine whether the monitored branch instruction is indicative of malware. Other embodiments are also described and claimed.

    摘要： Embodiments of apparatuses and methods for hardware enforced memory access permissions are disclosed. In one embodiment, a processor includes address translation hardware and memory access hardware. The address translation hardware is to support translation of a first address, used by software to access a memory, to a second address, used by the processor to access the memory. The memory access hardware is to detect an access permission violation.
