Abstract

The invention provides a protection method and system for BMC firmware refresh, the method comprising the following steps: S1, verifying an account password, if the account password is wrong, the firmware refresh authorization failing; if the password is correct, going to the next step; 2, importing / downloading the firmware image file, and carrying out signature verification on the firmware imagefile, if the verification fails, refusing the firmware refresh operation; if the verification is successful, carrying out the next step; S3, controlling the write protection switch of the flash chip storing the firmware image file to close and refreshing the firmware by using the control circuit; S4, after the firmware refresh is completed, resetting the write protection switch of the flash chip to the on state by default, and rejecting the modification operation. The invention solves the problem that the BMC firmware refresh protection mechanism of the prior art cannot comprehensively protectthe threat attack, realizes the omni-directional protection from refresh to running of the firmware, and greatly prevents the risk faced by the BMC firmware of the server management software.

Description

technical field [0001] The invention relates to the technical field of firmware refresh protection, in particular to a protection method and system for BMC firmware refresh. Background technique [0002] BMC (Baseboard Management Controller, Baseboard Management Controller) is a system-independent management software based on the industry-standard IPMI specification, used for remote management of servers, firmware upgrades, system monitoring and other operations. [0003] With the increasing status of BMC technology in the server industry, attacks against the server BMC system emerge in endlessly, including network layer attacks against refresh control; attacks against BMC firmware storage areas; and attacks against BMC firmware update image files. Once the BMC is attacked by the above threats, it will cause the server management system to collapse, or cause the server management system to be controlled by the attacker, and perform malicious operations on the server. Theref...
