Abstract: Cybersecurity is improved by automatically finding underutilized access capabilities. Some embodiments obtain an access capability specification, gather access attempt data, and computationally determine that the access capability has not been exercised sufficiently, based on an access capability exercise sufficiency criterion. Security is then enhanced by automatically producing a recommendation to harden a guarded computing system by reducing, disabling, or deleting the insufficiently exercised access capability. In some cases, security enhancement is performed by automatically hardening the guarded computing system. Access capability exercise sufficiency determination may be based on fixed, statistical, or learned time period thresholds or activity level thresholds, or on a combination thereof using confidence levels. Thresholds are compared to a detected time period value or a detected activity level value that is derived from the access attempt data, to determine exercise sufficiency.

Abstract: Provided are methods for learning to identify safety-critical scenarios for autonomous vehicles. First state information representing a first state of a driving scenario is received. The information includes a state of a vehicle and a state of an agent in the vehicle's environment. The first state information is processed with a neural network to determine at least one action to be performed by the agent, including a perception degradation action causing misperception of the agent by a perception system of the vehicle. Second state information representing a second state of the driving scenario is received after performance of the at least one action. A reward for the action is determined. First and second distances between the vehicle and the agent are determined and compared to determine the reward for the at least one action. At least one weight of the neural network is adjusted based on the reward.
