基于主机信息内容审计系统的设计与实现

为了检测受控网络的信息，介绍了一种基于主机内容信息审计系统,通过对包过滤系统和协议分析系统以及Libpcap库函数进行优化改进,来实现大数据量情况下对数据的审计。同时通过对部署该系统的主机性能进行测试，得到了对受测主机的详细内容，结果表明新系统大大提高了审计效率。

Design and implementation of audit system based on host information content

In order to detect controlled network information, this paper presents a system framework based on the host content of the information audit system. By optimizing the packet filtering system, protocol analysis system and Libpcap treasury function, the data audit is achieved under the circumstance of large amount of data. In addition, through the performance test on the host deploying the system, the details of the host were gained. The testing result shows that the new system has greatly enhanced the efficiency of the audit.
