Problems solved by technology

The patch program is added to the BIOS, and the new BIOS version is compiled to upgrade the client. Since the BIOS program needs to be upgraded, it will have a greater impact on customer use.
As one of the two most important firmwares at the bottom of the server, the BIOS is responsible for the initialization of the server hardware and the booting of the operating system. Frequent upgrades of the BIOS software will cause instability to the customer's use, and this security vulnerability upgrade solution will have an impact on the customer's business operation. stability risk
[0003] Aiming at the problem that the BIOS code modification method in the prior art has security risks and affects work stability, there is currently no effective solution

Abstract

The present invention discloses a method and device for repairing security loopholes in a server. The method includes: generating security BIOS codes that have patched loopholes, and generating a firmware upgrade patch based on the difference between the security BIOS codes and the existing BIOS codes; starting the BIOS in the server, through Poll the storage device to obtain the firmware upgrade patch, and check the firmware upgrade patch; in response to the verification, run the firmware upgrade patch to add a new firmware file system to the firmware volume of the BIOS, and any existing firmware file system in the BIOS The firmware filesystem does nothing. The invention can modify BIOS firmware in a safer way, improve stability and reduce risks.

Description

technical field [0001] The present invention relates to the field of switches, and more specifically, to a method and device for repairing server security vulnerabilities. Background technique [0002] In recent years, with the development of big data and cloud computing and other services, servers have gradually spread to all walks of life. As a tool for processing and storing the core data of enterprise customers, the server has very high security requirements. In recent years, Intel has reported CPU security vulnerabilities one after another. Such security vulnerabilities require upgrading the CPU microcode or modifying the configuration through the BIOS (Basic Input Output System) code. CPU register repair, generally by putting the patch program into the BIOS program to correct the problem. The method of adding the patch program to the BIOS and compiling a new BIOS version to upgrade the client will have a great impact on the use of customers because of the need to upgr...
