Abstract: In some embodiments, a system model construction platform may receive, from a system node data store, system node data associated with an industrial asset. The system model construction platform may automatically construct a data-driven, dynamic system model for the industrial asset based on the received system node data. A synthetic attack platform may then inject at least one synthetic attack into the data-driven, dynamic system model to create, for each of a plurality of monitoring nodes, a series of synthetic attack monitoring node values over time that represent simulated attacked operation of the industrial asset. The synthetic attack platform may store, in a synthetic attack space data source, the series of synthetic attack monitoring node values over time that represent simulated attacked operation of the industrial asset. This information may then be used, for example, along with normal operational data to construct a threat detection model for the industrial asset.

Abstract: An alerter augmentation system includes one or more processors that determine an alertness of an operator of a vehicle system. The one or more processors also generate operator input requests that are separated in time by a temporal delay. These input requests seek responses or action by the operator in an attempt to keep or make the operator alert. The one or more processors change one or more of the temporal delay between the input requests and/or a type of the input requests that are generated based at least in part on the alertness of the operator that is determined.

Abstract: According to some embodiments, a validation platform computer may interpret at least one received data packet to identify a control command for a controller of an industrial asset control system. The at least data packet being might be received, for example, from a network associated with a current operation of the industrial asset control system. The control command may then be introduced into an industrial asset simulation executing in parallel with the industrial asset control system. A simulated result of the control command from the industrial asset simulation may be validated, and, upon validation of the simulated result, it may be arranged for the control command to be provided to the controller of the industrial asset control system. Additionally, in some embodiments failed validation of a simulated result will prompt a threat-alert signal as well as prevent the command (e.g., data packet) from continuing to the controller.
