A file processing method and system

Abstract

The invention provides a file processing method and system, relating to the technical field of computers. The system comprises a server and all clients, wherein each client comprises a monitoring module and an uploading module; the monitoring module is suitable for monitoring whether a new file appears on the client; the uploading module is suitable for uploading client identification and file information to the server when the monitoring module monitors that a new file appears on the client; the server comprises a receiving module, a judgment module and a file information processing module; the receiving module is suitable for receiving the client identification and file information; the judgment module is suitable for judging whether the corresponding client is a trusted computer according to the client identification; and the file information processing module is suitable for performing safety marking on the file information and storing in a safe file information library when the client is judged to be a trusted computer, or otherwise comparing safe file information with the safe file information library and informing the client to perform treatment according to the comparison result. According to the invention, the misreporting of executable files in a closed network can be avoided, and the later maintenance cost can be lowered.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a file processing method and system. Background technique [0002] Computer network refers to the connection of multiple computers with independent functions in different geographical locations and their external devices through communication lines. Under the management and coordination of network operating systems, network management software and network communication protocols, resource sharing and communication are realized. A computer system for information transfer. Today, the main access is the Internet, and each terminal can obtain information from other terminals in the network through the Internet. However, information such as terminal secret information may also be obtained by other terminals in the Internet, especially for organizations such as enterprises. Therefore, in order to avoid information leakage, a closed network environment has been established for the ab...

Problems solved by technology

[0004] In the prior art, for the above-mentioned processing requirements, it is necessary to integrate the virus library of the anti-virus software of each terminal into a specific device, and then connect to the external network for upgrading and other processing processes before obtaining the black and white information of the executable file However, this process takes a long time, and the cost of maintenance and use is high; in addition, for the executable files newly appearing in each terminal in the isolated network, it is necessary to obtain the new virus database or patch from the external network, and check the executable files of each terminal in the isolated network The virus database is upgraded, the timeliness of the above method is very poor, and the cost of later maintenance and use is relatively high
