考虑黑客攻击下的信息系统安全投资策略分析
Investment strategy analysis of information system security in consideration of attackers
摘要
Abstract
In order to solve the problem of how a firm makes an optimal choice in developing information systems when faced with the following three modes: development by its own efforts, outsourcing them to a managed security service provider(MSSP) and cooperating with the MSSP, the firm's optimal investment strategies are discussed by modeling and analyzing the maximum expected utility in the above cases under the condition that the firm plays games with an attacker. The results show that the best choice for a firm is determined by the reasonable range of the cooperative development coefficient and applicable conditions. When the cooperative development coefficient is large, it is more rational for the firm to cooperate with the MSSP to develop the information system. When the cooperative development coefficient is small, it is more rational for the firm to develop the information system by its own efforts. It also shows that the attacker's maximum expected utility increases with the increase in the attacker's breach probability and cost coefficient when the cooperative development coefficient is small. On the contrary, it decreases when the cooperative development coefficient is large.关键词
