Security analysis of online digital goods business based on stochastic game net model

Abstract Digital goods business as a new mode of e‐commerce develops distinct features while it faces new threats. The aim of this paper is to show how a stochastic game nets (SGN) framework can be used to model and analyze digital goods business that is subject to various attacks. We illustrate our work in the following steps. A scenario of digital goods business security is built to identify action procedures of participants in the scene and to investigate the risk factors. Next, the interactive processes in digital goods business scenario is used for designing, establishing, and simulating an extensible graphically SGN model. The developed SGN model provides an efficient environment for defining uncertainties in digital goods business with proposed indicators. The findings of the study show that business security can be improved by using risk management actions, and the overall system costs can be reduced. Copyright © 2015 John Wiley & Sons, Ltd.
