Control method and control system for accessing to computer file contents

Abstract

The invention provides a control method and a control system for accessing to computer file contents. The control method is a system technology which is capable of analyzing the network communication of a relevant node, detecting and determining whether the network communication is abnormal according to a predetermined network communication rule, and if the network communication is abnormal, notifying a corresponding computer file control system of taking a protection measure to control the access to the contents of a protected file and prevent illegal access to the protected file to cause file leakage. Simultaneously, the invention provides a method of controlling the access to the contents of the protected file through network communication analysis. The network communication analysis system provided by the invention is capable of operating on a terminal, and operating either on the same terminal device with the computer file control system or on any network device of any layer. According to the system and the method, an effectively, complete, strict and advanced file security protection system is established; as a result, the information security problem in informatization is fundamentally solved.

Description

technical field [0001] The present invention relates to the technical fields of computer file system and information security, and more specifically, relates to a method and system for controlling access to computer file content. Background technique [0002] At present, in the field of computer and network information security technology, there are various information security products, and the information security technology adopted by these information security products plays a corresponding protective role in their respective information security links. However, on the whole, the entire process of information security protection is divided into independent links. For example, some information security products are mainly used in the transmission of information, while others are mainly used in the storage and use of information. These information security products come from different manufacturers, and they play different protective roles in different links. It is obvious...

Problems solved by technology

The firewall product is actually just an isolation technology, which protects the communication between different networks through the analysis of network communication, so as to prevent illegal personnel from invading and accessing the network, but it lacks access to information sources and computer file content on the terminal Therefore, from the perspective of the components of information protection, its information protection is incomplete

[0004] Also, from the point of view of information storage and use, some existing document security management systems or products can also play a protective role; however, such systems or products lack the protection and monitoring functions for information transmission. If illegal personnel invade the terminal through the network, the intruder will completely control and access the files on the terminal. This kind of document security management system does not have the function of network communication analysis and monitoring, and there are serious defects in information protection; at the same time, the file access control technology adopted by it is relatively The development and actual application of computer technology have lagged far behind

[0005] To sum up, in the current field of computer and network information security technology, there is still a lack of a complete, effective, rigorous and advanced integrated information security protection system. Therefore, how to establish an advanced and effective information security protection system an urgent and inescapable problem within the
