信息系统的风险控制与耗费成本

Risk Control and Expenses Cost of Information Systems

文章探讨了网络信息系统安全性概率与耗费成本之间的关系;将系统的安全性增量作为评价准则,为选择最优风险控制方案提供了依据;借助Lagrange乘子法,将成本增量进行合理的分配,使得网络信息系统的整体安全性达到最高。

This issue discusses the relation between security probability and expenses cost of the network information systems;being appraisement rule,the systems security increment provides gist to select the best risk control project;in virtue of Lagrange＇s multiplication,distributing logically the cost increment,it makes the integer security of network information systems to tiptop.
