引入人工免疫理论的入侵检测

由于计算机的安全问题与生物免疫系统具有惊人的相似性,特别是在网络入侵检测上,因此就产生了一个有意义的研究领域:引入人工免疫理论的入侵检测机制研究。首先介绍了入侵检测的概念和地位,然后在分析传统IDS缺陷的基础上,提出了在入侵检测中引入人工免疫理论。接着从AIS的生物原型入手,综述其仿生机理及其在计算机技术领域的应用,并介绍了阴性选择算法。然后通过局部修改portsentry,引入了人工免疫机制,并进行了仿真实验。

Intrusion Detection Based on AIS

As the computer safety system and the vertebrate immune system have much in common, especially in the field of intrusion detection, so the infall of these two fields leads to the filed: intrusion detection based on AIS, which has great research significance. First gives the concept of IDS and its importance. Then based on the analysis of traditional IDS 's limitation, it brings forward the import of AIS concept in the intrusion detection. After that, it gives a comprehensive overview of the application of AIS in the computer filed, which is started with the brief interpretative introduction of biological models of vertebrate immune system, then followed with the introducation to Algorithm of Negative Selection After that it partly modifies the portsentry code by importing the Artificial Immune mechanism and does simulation experimentation.
