Cyberspace security system

摘要

A system evaluates reliability, performance and/or safety by automatically assessing the targeted system's requirements. A cost metric quantifies the impact of failures as a function of failure cost per unit of time. The metrics or measurements may render real-time (or near real-time) outcomes by initiating active response against one or more high ranked threats. The system may support or may be executed in many domains including physical domains, cyber security domains, cyber-physical domains, infrastructure domains, etc. or any other domains that are subject to a threat or a loss.

主权项

1. An econometrics-based control system comprising:
a processor; a memory in communication with the processor, the memory configured to store processor implementable instructions, where the processor implementable instructions are programmed to: generate a stakes matrix that associates a failure cost to each of one or more system requirements, for each of at least one stakeholder, wherein each failure cost is associated with a monetary value; generate a dependency matrix that links at least one system component with a probability of failure for each of the one or more system requirements in instances when the corresponding system requirement failure occurs; generate an impact matrix to link a possible threat with each of the at least one system component; determine a mean failure cost based on a matrix multiplicative product of, at least, the stakes matrix, the dependency matrix, and the impact matrix, wherein the mean failure cost for a particular stakeholder represents a weighted sum in which:
the one or more failure costs for the particular stakeholder, wherein each of the failure costs is associated with one of the one or more system requirements, is weighted by a probability of failure of the associated system requirement, and all of the weighted failure costs for the particular stakeholder, are summed; and analyze the mean failure cost to determine a control strategy; and a communication component in communication with the processor and the memory, the communication component configured to communicate the control strategy to a controller component operable within the control system, where the controller component implements the control strategy.
