Design of multi-component cooperative network security detection system against intrusion

为了提高网络安全性能,提出基于多组件协作式检测的网络入侵安全检测系统设计方法。构建网络入侵的信号模型,对信号采用自适应匹配滤波器进行入侵特征检测,采用多组件协作级联滤波方法进行入侵信息过滤,实现入侵检测算法设计,在Matlab 7仿真软件中进行入侵检测系统的软件开发设计。采用硬件抽象组件、综合硬件组件和高层软件组件混合开发方法,实现多组件协作检测。测试结果表明,采用该方法进行网络安全入侵检测,具有较高的准确检测概率,提高了网络安全防护能力。

In order to improve the network security,a design method of network intrusion detection system based on multicomponent cooperative security detection is proposed in this paper.The signal model of network intrusion is constructed.The adaptive matching filter is used to detect the intrusion signal characteristic.The multi-component coordination cascade filtering method for intrusion information filtering is adopted to realize intrusion detection algorithm design.The software development and design of the intrusion detection system are carried out in the Matlab 7 simulation software.A mixed development method of the hardware abstraction component,integrated hardware component and high-level software component is used to implement multicomponent cooperative detection.The test results show that the method has high-accuracy detection probability for network security intrusion detection,and can improve the network security protective capability.
