计算机安全的多数问题都可以归结为对自我(合法用户、授权的行动等)和非我(入侵者、计算机病毒等)的识别,而生物免疫系统千百万年来一直在努力解决这一问题。基于免疫学理论的入侵检测技术正是受到生物免疫学的启发而提出的。文章介绍了基于免疫学理论的入侵检测技术的理论、算法,分析了它的优缺点并提出了进一步研究的方向。 Most problems with computer security can be attributed to the identification of self (legitimate users, authorized actions, etc.) and non-humans (intruders, computer viruses, etc.), and the biological immune system has struggled with the problem for millions of years. Intrusion detection technology based on immunology theory is inspired by bio-immunology. The article introduces the theory and algorithm of intrusion detection technology based on immune theory, analyzes its advantages and disadvantages and puts forward the direction of further research.
