Embodiment Construction

[0050] As mentioned earlier, the use of mobile storage devices brings information security risks. Especially an operational technology (Operational Technology, OT) system. The traditional OT system adopts a closed design, and it is difficult for network attacks to threaten it. However, with the development of automated manufacturing and process control technology, the OT system has widely adopted IT technology and is no longer a closed system. However, the current OT system still lacks a complete security mechanism, and because of its long running time, it is easier to subject to external cyber attacks.

[0051] On the other hand, the widespread use of mobile storage devices such as USB devices in OT systems such as digital factories greatly increases security risks. For example: use a USB device to copy firmware (firmware) or software from a file server in the enterprise's IT network, and copy it to one or more workstations on the factory production line. Once the USB devi...

Abstract

The invention relates to the technical field of information security, and especially relates to a control method, device and system for a mobile storage device, and aims to effectively prevent security risks caused by use of the mobile storage device. The device comprises a mobile storage device interface; a memory configured to store a device management program; and a processor configured to be used for calling the device management program, detecting whether the mobile storage device interface is connected with a mobile storage device or not, and destroying a file system on the connected mobile storage device after detecting that the mobile storage device interface is connected with the mobile storage device; In response to a file copying instruction, generating a first mirror image fileof a file system of the mobile storage device containing the target file; And recovering the file system of the mobile storage device by using the first mirror image file. As the equipment managementdevice recovers the file system of the mobile storage equipment by using the mirror image file, virus propagation caused by pulling out the mobile storage equipment in the anti-virus process can be effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a control method, device and system for a mobile storage device. Background technique [0002] Removable storage devices such as Universal Serial Bus (USB) greatly facilitate file storage. But it also brings security risks such as virus transmission and network attacks. [0003] At present, antivirus software is usually used to scan mobile storage devices to achieve the purpose of virus detection and antivirus. The use of antivirus software needs to know the characteristics of viruses in advance, and cannot effectively deal with emerging viruses. [0004] How to control mobile storage devices to effectively prevent security risks is an urgent problem to be solved at present. Contents of the invention [0005] In view of this, the present invention provides a control method, device and system of a mobile storage device to effectively prevent security risk...
