摘　　要：网络的发展为信息传递带来了极大的方便,也对中国政治、文化等有害信息的流入带来了便利。网络需要设置"关卡",使用安全监视技术识别出有害信息的来源并予以过滤或封堵。在此基础上设计出一种网络信息过滤系统。该系统采用C/S软件模型,主要是通过数据审计技术实现对TCP/UDP/HTTP消息地过滤和报警。经过测试,性能基本达到了设计要求。该系统的功能还要进一步完善以适应互联网发展的需要。The development of network gives not only the convenience for information communication, but also the opportunity for malicious information spreading. However, a ＂toll-gate＂should be deployed, which uses security monitor technology to identify the source of the malicious information in the network and filtrates those malicious information. For this purpose, a network information filtrating system is designed, in which C/S model is adopted. It could make alarming and filtering on TCP/UDP/HTTP information by data auditing. The system capability satisfies the basic requirement of the design. And the system functions must be further improved in order to suit the development of internet.
