改进的否定选择算法在入侵检测中的应用

针对基于否定选择算法入侵检测系统检测率低的问题,提出一种新的入侵检测算法,着重分析了检测器生成模块,对原否定选择算法做出了改进。改进算法主要对采用了基于空间包含的匹配算法和B、T双检测器来进行检测,增强检测器的多样性,提高了入侵检测系统的检测能力。最后通过实验证明,改进的否定选择算法提高了入侵检测系统的检测率。

Application of Improved Negative Selection Algorithm in Intrusion Detection

Negative selection algorithm for intrusion detection system has low detection rate,so a new intrusion detection model is proposed to analyze the detector generation mode and improve original negative selection algorithm.Improved algorithm mainly uses space-based matching algorithms and contains B,T dual-detector to detect for enhancing the diversity of detectors,improving the IDS’ detection capabilities.The experiments show that the improved negative selection algorithm promoted the detection rate of intrusion detection system.
