Abstract

This paper looks at the economics associated with botnets. This research can be used to calculate territorial sizes for online criminal networks. Looking at the types of systems we can compare the time required to maintain the botnet against the benefits received. In doing this it will be possible to formulate economic defence strategies that reduce the benefits received through the control of the botnet. We look at the decision to be territorial or not from the perspective of the criminal bot-herder. This is extended to an analysis of territorial size. The criminal running a botnet seeks to maximize profit. In doing this they need analyse the costs expended and benefits received against the territorial size. The result is a means to calculate the optimal size of the botnet and the expected returns. This information can be used to formulate security strategies that are designed to reduce the profitability of criminal botnets.
