安全等级对信息系统安全技术策略的影响研究----以防火墙和IDS技术组合为例

The influence of security rank on the technology portfolio and configurations of firewall and IDS was researched through game theory by this paper. It shows that the higher the security rank the bigger deterrence to hackers whose intrusion probability would be decreased. The security rank is not always improved when only one of the technology configurations is improved, and it is improved when both of the two technology configurations are coordinated with each other, which illustrates that the higher the security rank the higher requirement of security technology portfolio and configuration. The equilibrium strategy is also compared to the one without considering security rank, and the latter is an extremity of the former, which could not be reached or with no need to get.
