Title: An Analytical Approach to Regulation of Security Investments in the Internet

Abstract: Continuous proliferation of threats, evolution of attackers' choice of media and techniques, and the alarming erosion of privacy have made information security an important need of our increasingly IT-dependent society. Besides the technological barriers, security and privacy are affected by the investment decisions and behavioral traits of the end-users, service providers and content developers. This talk will introduce an analytical approach to a better understanding of the selfish incentives and strategic decisions of the involved agents with the goal of developing more efficient regulatory policies. Namely, I will present a model for the investment decisions of private ISPs in probing incoming and outgoing traffic for security threats, and the macro-level effect of these individual decisions. I will discuss the phenomenon of free-riding and the impacts of shortsightedness and limited rationality of the decision makers. I will examine the effectiveness of command-and-control regulatory policies, such as mandating investments and requiring minimum bilateral protection by security vendors, as well as economic incentive policies such as subsidies or seeding the ISPs with security measures, and a honeypot based punishment of ISPs that the threats originate from. For each of such policies, I will show the effect on the social and individual utilities as well as the overall network security in the equilibria. I will also explore the efficacy of these policies when the regulator has only a restricted region of jurisdiction, i.e., only a subset of ISPs can be mandated, seeded, or penalized.
