A port management method, system, device and computer-readable storage medium

Abstract

The invention belongs to the field of port management. The invention discloses a port management method, system, equipment and a computer-readable storage medium. The permissions corresponding to N USB ports are written into the SMBIOS through the BIOS, and the USB device is inserted under the OS. In the case of a USB port, the OS queries the SMBIOS for the authority corresponding to the USB port inserted into the USB device, and sets the driver parameters of the USB device according to the authority corresponding to the USB port inserted into the USB device. Since the permissions of the USB ports are all written into the SMBIOS by the BIOS, the setting of the USB port permissions is realized from the bottom layer. Compared with the prior art, using third-party software under the OS to manage the permissions of the USB ports is more secure. Because the third-party software is uninstalled, the USB port cannot be managed, which improves the stability and security of the USB port management and does not require additional hardware, which saves costs.

Description

technical field [0001] The invention relates to the field of port management, in particular to a port management method, system, equipment and computer-readable storage medium. Background technique [0002] With the advent of the era of big data, data security has attracted more and more attention. The USB (Universal Serial Bus, Universal Serial Bus) port is widely used as a data transmission interface, and the authority of the USB port has an undoubted impact on data security. For example, by managing the permissions of the USB port, the USB port can only recognize the keyboard and mouse, but not the USB storage device, or restrict the computer to only read the data in the USB storage device connected to the USB port, but not to the USB storage device connected to the USB port. Write data to a USB storage device connected to the USB port. In the prior art, when managing the USB port, third-party software is run under the OS (Operating System) to manage the authority of th...

Problems solved by technology

For example, by managing the permissions of the USB port, the USB port can only recognize the keyboard and mouse, but not the USB storage device, or restrict the computer to only read the data in the USB storage device connected to the USB port, but not to the USB storage device connected to the USB port. Writing data to a USB storage device connected to the USB port

In the prior art, when managing the USB port, third-party software is run under the OS (Operating System) to manage the permissions of the USB port, but once the third-party software is maliciously uninstalled, the USB port cannot be managed, which is safe. less stable

Or by installing a USB port permission control chip at the USB controller corresponding to the USB port, but additional hardware needs to be set, which will increase the hardware cost
