  • Patent number: 10262143
    Abstract: A system and method for systematically undertaking model-based security analysis of a cyber physical system (CPS) is provided. In one example, a cyber model simulation and a control system simulation are mapped using various methods to determine which portions of the cyber-model simulation and the control system simulation are correlated with one another. Using the determined correlation, when a cyber-attack is generated on the cyber model simulation, a corresponding attack hook can be generated for the control system model. The attack hook is configured to be integrated into the control system model so as to mimic the effect on the control system that a cyber-attack can engender. Once one or more attack hooks are generated, the user can place the hooks into the control system simulation schemas and run a series of simulations to determine the effects of a cyber event on the control system in a CPS.

    Abstract: In a virtualized computer system operable in more than two hierarchical privilege levels, components of a hypervisor, which include a virtual machine kernel and virtual machine monitors (VMMs), are assigned to different privilege levels. The virtual machine kernel operates at a low privilege level to be able to exploit certain features provided by the low privilege level, and the VMMs operate at a high privilege level to support execution of virtual machines. Upon determining that a context switch from the virtual machine kernel to a VMM is to be performed, the computer system exits the low privilege level, and enters the high privilege level to execute a trampoline that supports context switches to VMMs, such as state changes, and then the VMM. The trampoline is deactivated after execution control is switched to the VMM.

  • Patent number: 10120738
    Abstract: Guest memory data structures are read by one or more read operations which are set up to handle page faults and general protection faults generated during the read in various ways. If such a fault occurs while performing the one or more read operations, the fault is handled and the one or more read operation is terminated. The fault is handled by either dropping the fault and reporting an error instead of the fault, by dropping the fault and invoking an error handler that is set up prior to performing the read operations, or by forwarding the fault to a fault handler that is setup prior to performing the read operations. If no fault occurs, the read operations complete successfully. Thus, under normal circumstances, no fault is incurred in a read operation on guest memory data structures.

  • Patent number: 9946819
    Abstract: Buffer credits are starved upon a storage area network (SAN) switch. The starved buffer credit restricts a SAN switch buffer and enables a smaller load to stress the SAN switch, effectively emulating a larger load. Credit starvation may partially inhibit a SAN switch from delivering frames resulting in the filling of the SAN switch buffer and corresponding computational stress. The emulated load allows for all ports of a SAN switch to be simultaneously tested without the need or expense of a large number computing devices stressing the SAN. The SAN switch may be located within a test SAN environment or may be located in a functioning SAN environment to determine SAN bottlenecks prior to critical loading.

  • Patent number: 9871729
    Abstract: A non-transitory computer program product with computer readable program code for system detection and flow control. The throughput and response time of the system are acquired, where the throughput reflects the number of requests from outside the system that has been processed by the system. The response time reflects time required by the system to process requests from outside the system. Acquiring throughput and response time includes directly sampling the throughput and the response time of the system; and conducting noise filtering on the sampled throughput and response time. A system performance characteristic parameter based on the filtered throughput and response time is obtained and is used to describe congestion condition of the system to determine whether there is a bottleneck in the system. Detecting a bottleneck and flow control is provided in a simple and effective way to ensure that requests are processed in time.

  • Patent number: 9817779
    Abstract: A redirected USB device that does not fall within well-defined device-classes requires special treatment as redirection software will not always permit the servicing of universal serial bus request blocks (URB) on the same thread that the URBs are received. This results in the redirected USB device not functioning properly. A virtual USB bus driver may intercept the URBs so that a temporary kernel buffer can be created. The temporary kernel buffer stores the data necessary for processing the URBs. The temporary kernel buffer is queued along with the URB so that regardless of the thread for processing the URB, the data associated with the URB is preserved so that the vendor-specific application at the client may properly service any request.
