Read-write control method and system of mobile storage device based on micro-filter

Abstract

The invention discloses a read-write control method and system of a mobile storage device based on a micro-filter, and belongs to the technical field of information security. The method comprises the following steps: registering a micro-filter in an I / O manager of a file system, and setting the micro-filter to be automatically bound with all volume equipment on terminal equipment; acquiring a handle of the microfilter, and registering a callback function corresponding to IRP operation of the file according to the handle, wherein the micro-filter is used for monitoring IRP operation, and the file system preferentially calls a callback function before the file is subjected to read-write operation; and in the callback function, performing read-write access control on the mobile storage device according to the device identifier and the permission label of the mobile storage device. As the read-write control of the mobile storage device is improved on the basis of the file level, compared with the improvement on the hardware level, the cost can be effectively reduced.

Description

Technical field [0001] The present invention belongs to the field of information security, and more particularly to a read / write control method and system of a microfilter based mobile storage device. Background technique [0002] Due to the increasing development of information, mobile storage devices as file dump and transfer tools, its important role in daily life is increasingly highly highlighted, bringing great convenience to people's lives. At the same time, it also provides convenience to the criminal crime. The criminal can pull the mobile storage medium and copy important files and run malicious virus programs at will. Since the read writing of the mobile storage device does not have effectively control, not only the stolen of sensitive information and important data, it will make the security of the host have a great threat, and the impact of the impact is very bad, resulting in a lot of losses. . Therefore, research on this issue of host information is very importan...
