    摘要： An apparatus and method for efficient process-based compartmentalization. For example, one embodiment of a processor comprises: execution circuitry to execute instructions and process data; memory management circuitry coupled to the execution circuitry, the memory management circuitry to manage access to a system memory by a plurality of related processes using one or more process-specific translation structures and one or more shared translation structures to be shared by the related processes; and one or more control registers to store a process-specific base address pointer associated with a first process of the plurality of related processes and to store a shared base address pointer to identify the shared translation structures; wherein the memory management circuitry is to use the process-specific base address pointer in combination with a first linear address provided by the first process to walk the process-specific translation structures to identify any permissions and/or physical address associated with the first linear address, wherein if permissions are identified, the memory management circuitry is to use the permissions in place of any permissions specified in the shared translation structures.

    摘要： Various embodiments are generally directed to techniques for detecting malware in a manner that mitigates the consumption of processing and/or storage resources of a processing device. An apparatus may include a first processor component of a processing device to generate entries in a chronological order within a first page modification log maintained within a first storage divided into multiple pages, each entry to indicate a write access made by the first processor component to a page of the multiple pages; a retrieval component of a graphics controller of the processing device to recurringly retrieve indications from the first page modification log of at least one recently written page of the multiple pages; and a scan component of the graphics controller to recurringly scan the at least one recently written page to detect malware within the at least one recently written page.
