    摘要： Technologies for monitoring system API calls include a computing device with hardware virtualization support. The computing device establishes a default memory view and a security memory view to define physical memory maps and permissions. The computing device executes an application in the default memory view and executes a default inline hook in response to a call to an API function. The default inline hook switches to the security memory view using hardware support without causing a virtual machine exit. The security inline hook calls a security callback function to validate the API function call in the security memory view. Hook-skipping attacks may be prevented by padding the default inline hook with no-operation instructions, by designating memory pages of the API function as non-executable in the default memory view, or by designating memory pages of the application as non-executable in the security memory view. Other embodiments are described and claimed.

    摘要： An endoscopic bioptome having a proximal end and a distal end includes a proximal handle assembly including first and second actuators, a distal end effector assembly having jaws for cutting tissue samples, and a hollow member extending between the handle and the end effector assembly. The hollow member includes a first axial portion extending from the proximal end to a second axial portion at the distal end of the hollow member. The second axial portion is more flexible than the first axial portion. The bioptome further includes a control member connected at the proximal end to the handle assembly and at the distal end to the end effector assembly. Actuation of the first actuator causes the control member to open and close the jaws. The bioptome further includes a deflecting device connected at the proximal end to the second actuator and extending through at least a portion of the hollow member. Actuation of the second actuator causes the deflecting device to axially displace into the second axial portion to deflect the distal end of the hollow member.

    摘要： Systems, methods, and computer program products that provide for the use of a type 2 VMM to de-link or isolate underlying processor hardware from an operating system. This may allow the launching of a task that requires direct access to processor hardware, where such access requires the absence of an operating system. Such a task may take the form of a type 1 VMM, such as an information security or integrity VMM, e.g., an anti-malware VMM.
