Abstract

The invention provides a removable storage device permission management method and system based on a domestic operating system. The system includes: a real-time monitoring layer and an interception processing layer, and the real-time monitoring layer is used for monitoring insertion of the removable storage device, analyzing a storage control strategy of the removable storage device, sending control data related to the storage control strategy to the interception processing layer, and re-mounting a mounting directory of the removable storage device in a specified format of a virtual encryptedfile system. And the interception processing layer is used for intercepting the file access of the application layer to the removable storage device and controlling the file access behavior accordingto the control data generated by the control data updating module. According to the scheme provided by the invention, the system is high in compatibility, high in client security and convenient and flexible to deploy. The method does not depend on a specific environment, does not need to specially process the mobile storage device, and is high in flexibility. Permission subdivision management of the mobile storage device can be realized.

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 ...
