摘要
在Netfilter框架下,由于网络的自组织性和开放性,导致网络受到入侵的概率增大,Netfilter框架下入侵信号具有多频特征,对Netfilter框架下多频入侵信号进行准确检测的基础是进行特征分析,传统方法采用时频特征分析方法进行入侵检测,无法有效定位多频入侵信号的宽带时频特征,提出一种基于波束响应分布特征分析Netfilter框架下多频入侵信号检测方法。进行Netfilter框架下的网络入侵模型进行数学分析和信号分析,提取Netfilter框架下多频入侵信号波束响应分布特征,对已解码的Net-filter下的多频入侵特征和WZ帧进行内插值分析,由此实现入侵检测,仿真结果表明,采用此方法进行多频入侵检测的准确度较高,性能优越,在网络安全防护等领域具有较好的应用价值。
