Abstract

The present invention discloses a USB data transmission control method, apparatus and system, and a control component. The method comprises: acquiring USB data of interaction between a host and a universal serial bus USB device; analyzing the USB data, so as to obtain a behavior analysis result of the USB device; according to the behavior analysis result, identifying a risk behavior that may cause data leakage; and terminating data transmission corresponding to the risk behavior between the host and the USB device. According to the method disclosed by the present invention, by analyzing the acquired USB data, and thus obtaining the risk behavior that may cause data leakage and then terminating the data transmission corresponding to the risk behavior between the host and the USB device, the problem that it is time-consuming and laborious to prevent an illegal user from stealing important files or data by manually shielding the USB interface in the prior art is solved; and a USB device control manner becomes finer and more flexible.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a universal serial bus (English: Universal Serial Bus, abbreviated: USB) data transmission control method, device, USB control component and USB control system. Background technique [0002] With the popularity of USB technology and smart components (such as smart phones, etc.), the USB interface on the host (including computers, servers, etc.) has become an important way to leak the internal data of the host. In enterprises and institutions, users can easily Illegally copy the internal enterprise data stored on the host computer through USB interface devices (such as smart phones, U disks, USB mobile hard disks, mobile burners, and other storage devices with USB interfaces), thereby posing data security threats. In serious cases It will cause immeasurable losses to the enterprise. Based on this, in the prior art, in order to prevent the information on the host...
