Research And Implementation On File Monitor System Based On Windows Driver

With the rapid development of computer technology, the computer has been graduallyapplied to all kinds of fields. Today, society has entered the fourth stage of computerdevelopment: the Internet Age. The development of corporate internal network synchronizeswith the development of enterprises. When the network combined with a business, they glowinfinite splendor. However, the emergence of computer networks is not only bringsconvenience to people’s work, but also make some important information in danger.Emergence of network virus bring huge security threat and economic losses to manyenterprises and research institutions, but with the more emphasis on network security,antivirus software, network firewalls and other technologies the more mature, the securitythreats from outside the enterprise have been steadily and controllable. The existence ofenterprise security risk, because of its random and uncontrollable characteristics has beenmore and more attention. Important documents of internal are theft or changed maliciously, itbrings huge economic losses to the research institutions and enterprises. For solve thisproblem, this article describes a driver file monitoring system based on Windows, throughrecord to operating to one of the key document on the computer to prevent the leakage ofimportant information in the company. This article describes the design and loading of thedriver, the file operations monitoring technology, encryption and decryption algorithm andnetwork transmission technology. Through multiple technologies of combining to achieve thefile operations monitoring system, it prevents exist dangerous of the enterprise effectively.
