Network information content security: a framework for intelligent analysis and monitoring

The security assurance of network is critical to the whole modern world. As the increasingly occurred common network security incidents, current network security approaches are not sufficient. To transcend these limits, we should synthetically analyze security related factors from various kinds of sources and visual perspectives. Therefore we present a general framework for intelligent analysis and monitoring the security of network information content in high-speed network. The system can intelligently gather and transform various channels of non-structured, semi-structured and structured data based on broadband network; carry on security assurance related characteristic selections and topic identification; perform social network analysis of email and BBS; and fuse analysis of technical, social, economic and political triggers to information security incidents. The system can help information security experts find the association rules in the results from various analyzing levels, and visualize association patterns by their relational structures from link analysis techniques and provide early warning to system administrators.
