Minimizing Network Risk with Application to Critical Infrastructure Protection

ABSTRACT

The risk posed by natural disasters and terrorist attacks on critical infrastructure sectors such as the power grid, water supply, and telecommunication systems can be modeled by network risk. However, there is currently no definition of risk for a network. A new definition of network risk is proposed and applied to optimal allocation of a fixed budget such that network risk is minimized for two cost models: Linear and non-linear. It is shown that in both cases, risk minimization is achieved by ranking nodes and links according to their damage value and degree sequence. Furthermore, the critical nodes and links are identified as those with the highest allocation of funds.
