Abstract


Distributed information resources safe use monitoring technology is a research hotspot in recent years . General enterprises and institutions of the system administrator , usually the data stored on the server for easy download. However, if the data content and user behavior is not controlled , it will cause a huge loss of information , even confidential information leakage. Therefore, the strengthening of the network bandwidth, server , and a variety of information resources using controls to protect information assets has national significance . Firstly, analysis of a variety of traditional access control model features and shortcomings , and then systematically studied the next generation access control model UCON, a comprehensive analysis of the model access control mechanisms and deficiencies ; download behavior for the user to control the problem , research a network packet capture technology , protocol analysis technology and communication blocking techniques designed UCONpreA1OnB2 model, implementation of anti- malware download subsystems , real-time monitoring user download behavior ; access control for a server process problem, a WDM driver model and file system filter driver technology , designed for monitoring UCONpreA0 file server model to achieve a file server monitoring subsystem , the process can take the initiative to intercept illegal operations on files ; demand for file anti-phishing , the structure of the composite document , Word documents and Excel document structure is proposed based on finite automata double analytical method, on the basis of design and implementation of resource security filtering subsystem , content-based file filtering. Experimental results show that anti-malware download subsystem can take the initiative to block excessive users download , monitor and regulate the user download behavior ; file server monitoring server monitoring subsystem can access its own process behavior , which can effectively protect the target file ; resource security filter subsystem can efficiently parse common file formats , file content security detection , which can effectively prevent the leakage of classified documents and illegal file uploads. Currently, the three subsystems have been put into use , stable , reliable work.
