Problems solved by technology

For some categories that are not included in the USB device redirection policy issued by the redirection management system, such as custom devices, the client will allow redirection of these devices by default, so that the client is very easy to use some unsafe and maliciously connected devices Redirect to the target client, threatening the operation security of the entire network
In addition, for those multi-category devices, such as all-in-one printing and scanning machines that can be used as both printers and scanners, if the configuration information in the redirection policy delivered by the redirection management system Image capture devices (scanners belong to image capture devices) are allowed to be redirected. At this time, the printer cannot be redirected according to the redirection policy issued by the redirection management system.

Abstract

Embodiments of the present invention provide a USB device redirection method, device and system. Wherein, the method includes: after delivering to the client the first redirection policy corresponding to the user or user group to which the client belongs, receiving the basic device information of the USB device to be redirected reported by the client; The basic information of the device is used to determine the second redirection strategy; the second redirection strategy is sent to the client, so that the client selects the first redirection strategy and the One of the second redirection policies is used as the final policy, and a corresponding redirection operation is performed according to the final policy. The embodiment of the present invention solves the problems existing in the prior art, and improves the flexibility and safety of device redirection control.

Description

technical field [0001] The invention relates to communication technology, in particular to a USB device redirection method, device and system. Background technique [0002] USB (Universal Serial BUS, Universal Serial Bus) device redirection, that is, the client computer connected to the USB device intercepts the USB device data reported by the bus driver, and forwards the intercepted USB device data to the remote target computer to realize the The USB device of the client computer is delivered to the desktop of the remote target computer. [0003] In the prior art, the redirection management system pre-stores USB device redirection policies corresponding to each user or user group. The redirection management system manages the redirection authority of each user or user group according to the USB device redirection policy corresponding to each user or user group. Described USB device redirection strategy generally comprises: whether this user or user group is allowed to use...
