USB status restriction equipment and method of use thereof

Abstract

The invention relates to a USB state limiting device for reducing abuse of USB device and reinforcing the safety of internal sensitive information of host computer, which comprises a communication module, a control module, a connecting module, a USB port module and an authority module. The communication module is used for realizing communication. The control module is used for controlling the work of internal individual modules in the USB state limiting device, coordinate and control communication work with outside, and monitor whether USB device is inserted into the USB port. The connecting module is used for establishing the connection between the host computer connected with the USB state limiting device and the USB device which is inserted into the USB port. The USB port module is used for connecting with the USB device which is inserted into the USB port to complete information interaction. The authority module is connected with the control module, and at the same time has the functions of approval and authority. The invention further provides a using method of the USB state limiting device.

Description

technical field [0001] The invention relates to the field of information security, in particular to a USB state limiting device and a using method thereof. Background technique [0002] In today's increasingly developed information technology, more and more data information, personal privacy and business secrets are stored or backed up in the host, and these sensitive information stored or backed up in the host are vulnerable to viruses or human attacks, resulting in the loss of sensitive information , missing or illegal tampering, not only bring huge economic losses to people, but also make it impossible to continue normal work. Therefore, the security and confidentiality of sensitive information such as data, privacy or business secrets are increasingly valued by people. [0003] In the prior art, the USB device represented by the U disk has been widely used in daily life and work due to its flexible use, convenience and portability, which greatly facilitates the exchange...
