Method and system for tracking movable media and electronic document circulation trajectories of movable media in LAN

Abstract

The invention provides a method and system for tracking movable media and electronic document circulation trajectories of the movable media in an LAN. The method comprises the steps that S1, movable access media which are access to a computer are identified, and the equipment identification of the movable access media and the information of the current computer are acquired; S2, the operation request of a user thread to an electronic document in the movable access media is captured, and an effective operation request within a competence range corresponding to a security classification identification is selected according to the security classification identification of the electronic document in the movable access media; S3, corresponding operation is conducted on the electronic document in the movable access media according to the effective operation request, and the specific information of the operation is recorded in real time; S4, a dynamic electronic document circulation trajectory tracking model is established in the LAN by combining a GIS, the movable media and the electronic document circulation trajectories are tracked in the dynamic electronic document circulation trajectory tracking model according to the equipment identification of the movable access media, and visual monitoring of the electronic document circulation trajectories in the LAN is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and system for tracking mobile media in a local area network and electronic file circulation tracks based on visualization tool GIS technology. Background technique [0002] In recent years, information security issues have become the focus of people's attention. According to the survey results of authoritative organizations: more than 85% of security threats come from within the enterprise, and as mobile storage devices replacing floppy disks (such as U disk, mobile hard disk, mobile CD-ROM, etc.), Because of its flexible and convenient use, it has been rapidly popularized in the process of enterprise informatization, and it is also an important mobile medium for confidential computer information exchange. More and more sensitive information, secret data and archives are stored in mobile media, which brings considerable security risks to enterprise inform...

Problems solved by technology

However, there will still be information leakage when encrypting important electronic files or controlling their access rights, and once leaked, when and on which computer the electronic file was copied, modified, and pasted. It is impossible to obtain them, and it is impossible to know whether illegal personnel or programs have performed unauthorized operations on important files. Obviously, file encryption has not fundamentally solved the problem.
