Network Security and Contagion

Speaker/Bio

Eran simhon, PhD candidate, system Engineering, Boston University. In my research, I use game theory to study the behavior of customers in networks and cloud computing. Especially I am interested in analyzing different reservation systems and to find the mechanism that will maximize the provider's profit in those systems. I am also interested in learning models in games.

Abstract

In this talk I will summarize the paper "Network Security and Contagion", (Acemoglu et. al 2014). The paper develop a theoretical model of investment in security in a network of interconnected agents. Using Game theory tools, the authors show that the investment level depends on the network structure, the cost function of the security investment and the cost function of the attack. The authors also provide conditions for under-investment and over-investment for different network structures.
