While network - based intrusion detection systems usually detect packet headers or part of those headers , this system examines the packet payload as well as headers . not only the attributes are detected respectively , but also the relationships of attributes occurrence are detected according to a set of conditional rules , which is generated automatically by a machine learning algorithm 常见的基于网络的入侵检测系统一般只对网络数据包的包头或包头中的某些内容进行考察,而本文实现的原型系统不仅考察数据包的包头,而且还考察数据包应用负载的部分内容。
