随着入侵技术的逐步成熟,攻击者往往在入侵目标主机之前攻击入侵检测系统,使其丧失保护功能.首先分析了当前常用的分布式入侵检测系统的缺陷及攻击者常用的攻击方法,然后在此基础上提出了一种能够防止自身遭受拒绝服务攻击的入侵检测系统模型.
With the gradual maturity of intrusion technology, attackers often attack intrusion detection system before invade target host, so that they lose the protection function.Firstly, the defects of commonly used distributed intrusion detection system and attack methods commonly used by attackers are analyzed, Based on this, an intrusion detection system model that can prevent itself from denial of service attacks is proposed.
