Abstract: A system, circuit, and method are described, among other things. An illustrative system is disclosed to include a processor and a memory storing data for processing by the processor. The data, when processed, causes the processor to receive an initiator message comprising a request to access one or more registers of a plurality of registers, determine that the initiator message corresponds to an entry of a privilege access table, determine a configured level of access control for the initiator message to access the one or more requested registers based at least in part on a group mapping table, and provide a level of access to the one or more requested registers corresponding to the received initiator message based on the initiator message corresponding to the entry of the privilege access table and based, at least in part, on the determined configured level of access control.

Abstract: A method of determining if a virtual machine is executing a network attack may include using a computing device operating a processor: receiving a plurality of jobs from a plurality of virtual machines being executed across time slices on a host computer in a computer network; executing the plurality of jobs using the processor; receiving data from hardware counters of the processor; and based on the data, determining whether or not a virtual machine of the plurality of virtual machines is executing a network attack.

Abstract: A system includes a network adapter and a processor. The network adapter is configured to receive packets from a network, to process the received packets in accordance with a policy, and to derive a packet digest from the received packets. The processor is configured to adapt the policy based on the packet digest derived by the network adapter, and to provide the adapted policy to the network adapter for subsequent packet processing.

Abstract: An Integrated Circuit (IC) includes functional circuitry and attack-protection circuitry (APC). The functional circuitry is to receive a supply voltage from a power-supply input. The APC is coupled to the power-supply input and includes a front-end circuit and an averaging circuit. The front-end circuit is to compare the supply voltage to a plurality of voltage thresholds, and to output a respective plurality of indications that indicate whether the supply voltage violates the respective voltage thresholds. The averaging circuit is to estimate, for a selected subset of the indications, respective duty-cycles at which the indications in the subset exceed the respective voltage thresholds. The APC is to trigger one or more attack detection events in response to the indications and the duty-cycles.
