Abstract

The present invention provides a removable storage device authority management method and system based on a domestic operating system. The system includes: a real-time monitoring layer and an interception processing layer. The real-time monitoring layer is used to monitor the insertion of a removable storage device, and the analysis can move the storage control strategy of the storage device, and send the control data related to the storage control strategy to the interception processing layer; at the same time, remount the mount directory of the removable storage device in the specified format of the virtual encrypted file system . The interception processing layer is used to intercept the file access of the application layer to the removable storage device, and control the file access behavior according to the control data generated by the control data update module. According to the solution of the present invention, the system has high compatibility, high client security, and convenient and flexible deployment. It does not depend on a specific environment, nor does it require special handling of removable storage devices, with high flexibility. It can realize the permission subdivision management of removable storage devices.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and system for managing rights of a removable storage device based on a domestic operating system. Background technique [0002] At present, there are relatively mature protection software for windows operating system on the market, but with the change of information processing requirements, there is an increasing need for domestic, safe and reliable operating systems and matching software for domestic operating systems. software. There are few existing data security protection software that support domestic operating systems. This type of protection software generally controls the access rights of removable storage devices. The purpose of control is mostly to protect removable storage devices and prevent viruses. For example, it can manage the read and write permissions, execute permissions, rename permissions, delete permissions and change permissions of removable ...
