In critical infrastructures consisting of discrete cyber and physical components, the correlations between them may be exploited to launch strategic component attacks that may degrade the entire system. We capture such correlations between cyber and physical sub-infrastructures using the conditional probabilities, and between cyber and physical components using first-order differential conditions...
We consider a class of infrastructures supported by cyber and physical components, which are subject to disruptions. We study reinforcement strategies for cyber and physical components to achieve resilience, specified by the probability of infrastructure survival, against disruptions using a game-theoretic formulation. The game utility function is a sum of the infrastructure survival probability term...
The anticipated proliferation of cyber components for collecting information and controlling operations of smart grids increases their vulnerability to a variety of cyber attacks. For instance, a large-scale simultaneous attack on smart meters to destabilize the grid could be feasible via cyber means, which is not viable via physical attacks alone. The interactions between the providers and attackers...
