入侵检测系统中模式匹配算法的改进OA北大核心CSCDCSTPCD
AMELIORATION OF PATTERN-MATCHING ALGORITHM IN INTRUSION DETECTION SYSTEM
入侵检测系统作为防火墙的合理补充,已经发展成为网络安全体系中的一个关键性组件.网络技术的飞速发展给入侵检测系统提出新的挑战,需要通过各种途径来提高系统性能,而模式匹配算法的优劣直接影响到入侵检测系统的核心模块——规则匹配模块的运行效率.通过对原有BM算法的深入分析,从如何增大模式不匹配时的滑动距离这一点出发,对BM算法进行改进与实现,并通过实验证明该方法提高了匹配效率.
Intrusion detection system ( IDS), as a rational supplement to the firewall, has been developed to be one of the key components of the network security system.IDS is facing new challenges due to fast development of network technology and therefore needs to be improved of its system performances through all kinds of approaches, and the operation efficiency of rule matching module, the hard core of IDS, is straight effected by the performance of pattern matchi…查看全部>>
