Port management method, system and device and computer readable storage medium

Abstract

The invention belongs to the field of port management, and discloses a port management method, system and device and a computer readable storage medium, permissions corresponding to N USB ports are written into an SMBIOS through a BIOS, when a USB port inserted into a USB device exists under an OS, the permissions corresponding to the USB port inserted into the USB device are inquired from the SMBIOS through the OS, and if the USB port inserted into the USB device exists in the SMBIOS, the permission corresponding to the USB port inserted into the USB device exists in the SMBIOS. And setting driving parameters of the USB equipment according to the permission corresponding to the USB port inserted into the USB equipment. As the permission of the USB port is written into the SMBIOS through the BIOS, the setting of the permission of the USB port is realized from the bottom layer, compared with the prior art that the permission of the USB port is managed by using third-party software under the OS, the permission security is higher, and the situation that the permission of the USB port cannot be managed due to the fact that the third-party software is unloaded is avoided. The stability and the safety of management of the USB port are improved, additional hardware is not needed, and the cost is saved.

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
