Web Content Audit And Monitoring Technology

By capturing and analyzing all or part of the information of network, Network Auditing and Monitoring System (NAMS) audit and monitor the network's information content and the behaviors. So NAMS can help users resolve security problems. Network Auditing and Monitoring covers multiple targets of network management field which was defined by Open System Interconnection (OSI). Being one kind of NAMS, Network Content Auditing and Monitoring System is used to audit and monitor the information content of network's data. Firstly, the research status of NAMS is analyzed in this thesis, which includes today's Firewall, IDS, and NCAMS technologies and products. Secondly, according to the requirements of NCAMS and the corresponding technologies, A distributed data capture and analysis model in NCAMS is put forward and addressed which can be the data capture and analysis component of NCAMS. Finally, this model is implemented and tested, and the test result indicates that this model is high-powered, flexible-disposed and extensible which adapts to the current status of network. The achievement of this research is that a data capture and analysis model is designed and implemented. Moreover, this model can greatly increase the flexibility, extensibility, reliability and efficiency of NCAMS. So, this research has some theory value in network auditing and monitoring field. Especially because using overseas security products are prohibited in some important departments of our nation, this research has furthermore application value in our country. This model has been applied in some security departments and taken a good effect.
