Research on Decision of Cyber Security Investment Based on Evolutionary Game Model

During the cyber security construction process, how to set proper security standard and investment quota in accordance with the important degree of its information is a universal problem of enterprises. We propose a dynamic Invest-Attack Model based on Information Asymmetry between the protectors and attackers of cyber security and make RD analysis to the proposed model with Evolutionary Game Theory. Finally, we analyze motivation of decision making of players of both sides from microcosmic perspective and put forward conclusion as well as policy suggestions.
