摘要
自计算机免疫学被引入到计算机安全领域以来,传统的免疫算法就存在着漏报率高的问题。针对上述问题,根据人工免疫系统的基本原理和方法,提出了一种具有可变阀值的免疫算法,并给出了详细的检测器生成和检测算法。该免疫算法通过给每个检测器设定阀值的方法,尽可能的扩大单个检测器的检测空间,从而使得整个检测器集合的检测空间达到最大,实现降低系统漏报率的目的。最后模拟实验结果表明,该免疫算法可以有效地降低系统的漏报率。
From the time when the computer immunology is introduced in field of computer security. The high rate offalse negafives of traditional immunology algorithm is a problem. An immunology algorithm with variable threshold is proposed to above problem and the method of detector production and checking are presented. For reduction rate of false negatives, the immunology algorithm expands space of detector set by used method that set threshold value for every detector. In the end, the feasibility of the algorithm is proved by simulation experiments.
