Host file security monitoring method

Abstract

The invention relates to the technical field of information security, in particular to a host file security monitoring and protecting method. The method is a file transparent encryption method based on a driver layer and is completely transparent to users; the users cannot sense file encryption and decryption in a use process; an application layer encryption method with higher security and quicker speed is used for assisting; and a file transparent encryption scheme based on a conventional file screening method is provided for more complicated software systems. According to the method, the process and files of a local computer are identified, and security files are automatically encrypted and decrypted, so that problems of memory mapping, file buffering and the like are solved, and the safety is increased.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a host file security monitoring and protection method. Background technique [0002] Digital content itself is easy to copy, and the development of network technology has led to the proliferation of illegal transmission. Inside the company, especially in some units where the information is confidential, employees are not allowed to take away the files and materials in the computer without permission. However, it is obviously not enough to rely on the self-consciousness of employees alone, especially some people want to steal company secrets with subjective malice, and the leakage of company confidential information directly leads to huge losses of economic benefits. With the increasing use of computers to create and process information electronically, protecting corporate information, data and documents has become a daunting and long-term task in corporate business ...

Problems solved by technology

[0007] (2) Lack of internal control technology for file information storage security: most of the current strategies and technologies for file information storage security are aimed at external threats, and rarely involve internal monitoring, lack of perfect internal control security measures, and 70% of leaking crimes It comes from the inside, so increasing the internal control security of terminal files is an urgently needed technology in the field of secure storage of file information

[0008] (3) Some file internal control security products on the market have the following defects: lack of a complete monitoring strategy, single monitoring function, and existence of one or another loophole

[0009] In addition, as a requirement for ease of use, the introduction of a secure system should not force users to change the operation and disposal habits of using files when no monitoring software is installed, and the introduction of monitoring protection should not greatly reduce the operating performance of the host
