Method and system for limiting USB (universal serial bus) storage device through file filter driving

Abstract

The invention relates to a method for limiting a USB (universal serial bus) storage device through file filter driving. The method comprises steps as follows: a policy configuration is saved, and when the USB storage device is inserted in a computer, the serial number of the currently mounted USB storage device is detected; information of the saved policy configuration is acquired; whether the serial number of the USB storage device is used legally is judged according to the policy configuration, and a permission is given to the USB storage device. A system for limiting the USB storage device through file filter driving comprises an engine server, a control console, a data acquisition server and a client side, wherein the engine server is connected with the control console and the data acquisition server, and the data acquisition server is connected with the client side. With the method and the system, use of the USB storage device can be limited universally and flexibly through a file filter driving module, the method and the system take effect on the USB storage device, and other types of USB devices cannot be limited.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and system for restricting USB storage devices driven by file filtering. Background technique [0002] With the widespread application of computer technology in office work, the security and confidentiality of office data is becoming more and more important. Especially for some confidential information, if it is leaked, it may cause serious consequences. At present, USB (Universal Serial BUS, Universal Serial Bus) storage devices are widely used. It has the characteristics of strong versatility, easy to carry, easy to use, large capacity, and long life. It has replaced the early 3.5-inch and 5.25-inch floppy disks. , plays an important role in data exchange and data backup. [0003] However, while these large-capacity mobile storage devices bring convenience to users, they also bring great security risks: For example, when employees leave the company, it is easy to c...

Problems solved by technology

[0004] In the prior art, in order to realize the effective monitoring and management of USB storage devices, the following two methods are usually adopted: 1. Use solid glue to seal the USB interface. If the sealing is not complete, it is still easy to open the seal of the solid glue , continue to insert the USB storage device into the USB interface for use; 2. Remove the USB interface of the computer. If the use of the USB interface is prohibited, all USB devices will be unavailable, and the convenience of the USB storage device will not be fully utilized.
