Securing interdependent assets
Abstract Stackelberg security game models have become among the leading practical game theoretic approaches to security, having seen actual deployment in the LAX Airport, the United States Federal Air Marshals Service, and the United States Coast Guard, among others. However, most techniques for computing optimal security policies in Stackelberg games to date do not explicitly account for interdependencies among targets. We introduce a novel framework for computing optimal randomized security policies in networked (interdependent) domains. Our framework rests upon a Stackelberg security game model, within which we explicitly capture the indirect spread of damages due either to malicious attacks or unintended failures. We proceed to specify a particular simple, yet natural model of damage spread based on a graphical representation of asset interdependencies coupled with an independent failure cascade model. For the general model, we present an algorithm based on submodularity of the att...
