Embodiment 1

[0027] figure 1 A schematic flow diagram of a USB mobile storage device access control method provided in Embodiment 1 of the present invention; including:

[0028] Step 101, when a universal serial bus USB removable storage device is detected on the terminal device, acquire the identification of the USB removable storage device.

[0029] For example, the USB mobile storage device access control device detects the USB mobile storage device on the terminal device. Specifically, the USB removable storage device access control device can be implemented through a monitoring program installed in the terminal device. The disk filter driver in the monitoring program will be loaded into the kernel when the terminal device starts, and monitor all the Plug-and-play (Plug-and-Play, PNP for short) action, the insertion of any USB mobile storage device will be recognized by the disk filter driver, and the USB mobile storage device identification can be automatically read from the USB mobi...

Abstract

An embodiment of the invention discloses a USB mobile memory device access control method, a USB mobile memory device access control device and a USB mobile memory device access control system. The USB mobile memory device access control method includes; acquiring identification of a USB mobile memory device; inquiring whether an access control table item corresponding to the USB mobile memory device exists in a local access control table or not, if yes, verifying user information; determining operation limit of the USB mobile memory device used by the user information on terminal equipment according to the access control table item; and controlling operations of the terminal equipment on the USB mobile memory device according to the operation limits. The USB mobile memory device access control method, the USB mobile memory device access control device and the USB mobile memory device access control system in the embodiment can solve the problem of poor universality in monitoring of the mobile memory device in the prior art.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a method, device and system for access control of a USB mobile storage device. Background technique [0002] The widespread use of universal serial bus (Universal Serial Bus, referred to as USB) mobile storage devices makes information transmission more convenient. If its use cannot be effectively controlled, there will be serious problems in intranet information security. [0003] In order to prevent confidential files, internal documents or private privacy on the intranet terminal from being taken away by people using USB mobile storage devices, and to prevent external virus-laden USB mobile storage devices from being inserted into intranet terminals and causing intranet computers to be poisoned, now One USB mobile storage device management solution is to prohibit the USB mobile storage device from being used on the terminal. However, this solution cannot flexibly c...
