  • Non-enclave access prevention
    Patent number: 10572395
    Abstract: A processing system includes an execution unit comprising a logic circuit to implement an architecturally-protected execution environment associated with a protected region in a memory, in which the execution unit is to execute application code stored in the protected region as a thread running in the architecturally-protected execution environment, determine that an access mode flag is set to a first value, detect an attempt by the thread to access data stored outside the protected region, and responsive to detecting the attempt and determining that the access mode flag is set to the first value, generate an exception.
    Type: Grant

    Inventors: Volodymyr Pikhur, Atul A. Khare
  • Profiling event based exploit detection
    Patent number: 9984230
    Abstract: Particular embodiments described herein provide for an electronic device that can be configured to execute an application in a system with an operating system, perform event tracing for the application, analyze each instruction pointer from the event tracing, and determine if an instruction pointer points to an orphan page of memory. The orphan page can be a region of code that is not associated with the application, a region of code that is unidentified, or unusual code that is not associated with the application. In addition, the event tracing can be an embedded application that is part of the operating system.
