Problems solved by technology

[0002] BMC is a baseboard management controller, which is a controller that performs remote management of servers, and SPI flash is an information memory. In the prior art, since BMC can write data to the serial peripheral interface flash memory SPI flash, it can also be read from Read data in SPI flash, therefore, for the user, it hopes that BMC is legal for the write operation of SPI flash, however, does not provide corresponding writing protection scheme in the prior art

Abstract

The invention provides a data detection method and detection equipment. The detection equipment is arranged between a BMC (baseboard management controller) and an SPI (serial peripheral interface) flash in a connected manner. The data detection method includes receiving first instructions transmitted by the BMC; judging whether the first instructions are illegal write instructions or not; prohibiting the SPI flash from executing operation corresponding to the illegal write instructions if the first instructions are the illegal write instructions. The data detection method and the detection equipment have the advantages that the instructions transmitted from the BMC to the SPI flash can be detected, the SPI flash can be prohibited from executing the operation corresponding to illegal writeinstructions if the instructions transmitted from the BMC to the SPI flash are the illegal write instructions, and accordingly write protection on the SPI flash can be implemented.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a data detection method and detection equipment. Background technique [0002] BMC is a baseboard management controller, which is a controller that performs remote management of servers, and SPI flash is an information memory. In the prior art, since BMC can write data to the serial peripheral interface flash memory SPI flash, it can also be read from Read data in SPI flash, therefore, for the user, it hopes that BMC is legal for the write operation of SPI flash, however, does not provide corresponding writing protection scheme in the prior art. Contents of the invention [0003] In view of this, the invention provides a kind of data detection method and detection equipment, to realize the write protection to SPI flash, its technical scheme is as follows: [0004] A data detection method is applied to a detection device, and the detection device is connected between a ...
