摘要
代价估算问题是入侵响应中成本分析的重要依据,因此也是影响入侵响应系统是否做出响应决策的关键问题.作者在分析了现有Northcutt的损失代价估算方法并对其代价估算规则进行了总结的基础上,提出了一种新的代价估算准则,并将基于该代价准则的成本分析模块应用到入侵响应系统中设计了基于成本分析的入侵响应系统,进而对该响应系统进行了损失代价估算、响应代价的估算,结果表明该项应用能够合理有效的利用有限的系统资源.
Evaluation of the cost is the important base of the cost-sensitive in the intrusion response system,so it is also the critical point for making a response determination in intrusion response system.After analyzing existing the cost evaluation method——Northcutt and summarizing its rules,this paper presents a new cost revaluation rule which could be applied to the cost-sensitive model in the intrusion response system,and estimate this system about loss cost revaluation and response cost revaluation.Then it conclude that this application can make full use of the limited resources efficiently and rationally in the system from the result of comparison and analysis.
