摘要： Various mechanisms are disclosed herein for the saving and restoring of virtual machine environment state. For example, virtual machine state can be either be saved or (multiple) snapshots can be taken of the virtual machine state. In the latter case, virtual processors can be allowed to run while the memory of the virtual machine state is being saved. In either case, virtual devices associated with the virtual machine environment can be quiesced such that these devices can prepare themselves to be saved. Once such virtual devices and memory are saved, they can also be restored. For example, restoration of memory can occur while virtual processors are running at the same time. And, moreover, restoration can occur in batches of pages, thus optimizing the response time for restoring saved data.

摘要： A method for managing software modules of at least two operating systems sharing physical resources of a computing environment, but running in different partitions separated by a virtualization boundary comprises accumulating module information in a virtualization subsystem that directs the creation and management of the partitions. The accumulated module information is used across the virtualization boundary to manage the use of the software modules. Also, a method for managing software modules comprises making at least two operating systems aware that they are being hosted in a virtualized computing environment.

摘要： Systems and methods for enabling trusted software to monitor and control USB traffic associated with a security extension of a host controller and devices in a USB topology is disclosed. A host controller proxy receives USB-related data from a host controller driver, determines whether the data is of a security interest, and if so, sends the data to a driver for a security extension executing in the trusted execution environment. Likewise, after software executing in the trusted execution environment evaluates and appropriately addresses data sent by the HCD proxy or data retrieved from a hardware security extension, the HCD proxy receives data from the trusted execution environment for further dissemination.

摘要： Protecting computer systems from attacks that attempt to change USB topology and for ensuring that the system's information regarding USB topology is accurate is disclosed. A software model is defined that, together with secure USB hardware, provides an ability to define policies using which USB traffic can be properly monitored and controlled. The implemented policy provides control over USB commands through a combination of software evaluation and hardware programming. Legitimate commands are evaluated and “allowed” to be sent to a USB device by a host controller. Illegitimate commands are evaluated and blocked. Additionally, the USB topology is audited to verify that the system's topology map matches the actual USB topology.

摘要： Techniques are disclosed to provide security for graphical user interface elements being displayed in a system in which a first, host operating system is used along with a second, high assurance operating system, where the first system provides at least some of the infrastructure for the second system. Graphical user interface elements associated with the high-assurance operating system are prevented from being obscured and from any partial transparency. Additionally, a piece of secret information is stored which can be displayed upon command by graphical user interface elements associated with the high-assurance operating system. Coordinating certain elements of the display of all graphical user interface elements associated with the high assurance operating system also helps to identify legitimate elements associated with the high assurance operating system, as opposed to impostor elements which are not. Where a windowing system is used, public title information is furnished to a host operating system windowing system to identify a window owned by a process running on a high-assurance operating system. Private title information associated with the same window is used only in the high assurance operating system.
