The invention provides a safety protection method and system for a BMC serial port. The safety protection method comprises the steps that S1, BMC serial port permission is distributed to legal users;S2, storing the legal user information into a legal user storage area; S3, when the terminal user is connected with the serial port line and uses the serial port, identity verification is carried outon the terminal user; And S4, when the number of verification failures exceeds a set threshold value, locking the serial port. According to the embodiment of the invention, the related security moduleis added in the BMC, the identity verification module is set, the authority is distributed to the legal user through the BMC, the user needs to carry out identity verification when using the BMC serial port, and the serial port can be used only after the verification is passed, so that illegal personnel are prevented from using the serial port, and the security of the BMC is improved. According to the method, hardware circuits of an existing server mainboard do not need to be modified at all, only relevant security models need to be added into the BMC in a software mode, the software processis changed, and therefore the method has the advantages of being high in practicability and high in operability.
Description
technical field [0001] The invention relates to the technical field of substrate control, in particular to a security protection method and system for a BMC serial port. Background technique [0002] BMC is the baseboard management controller of the server. It has been widely used in the server field. It uses the virtual keyboard, interface, mouse and power supply to provide remote management functions for the server. Users can remotely monitor the physical characteristics of the server through the network port of the BMC, such as The temperature and voltage of each component and the working status of the fan, as well as the power supply and chassis intrusion, etc. [0003] The serial port of the BMC is the UART port based on the RS232 protocol, which is used for BMC debugging and as an inspection interface for external maintenance. Specifically, view device information and online debugging by connecting the serial cable to the BMC. While the serial port brings convenience...
