Abstract

The invention discloses a system data monitoring and protecting method. The method comprises the following steps: loading a CPLD on a PECI bus; establishing and updating a white list in real time in the CPLD based on the BMC; and monitoring and / or controlling data transmission of the PECI bus by the CPLD based on the white list updated in real time. The invention further discloses a system data monitoring and protecting device. According to the method, the risk that the CPU register is tampered can be effectively avoided, and the safety of server design is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a method and device for monitoring and protecting system data. Background technique [0002] Platform Environment Control Interface (Platform Environment Control Interface, PECI) is a digital interface proposed by Intel. It is a dedicated single-wire bus between the CPU and system monitoring equipment. In the current server design, it is mainly used in the baseboard management controller (Baseboard Management Controller). Between Controller, BMC) and CPU, there is a host-device (host-device) architecture application. BMC can read CPU temperature and related device information through PECI bus, and can also configure threshold parameters of power supply and heat dissipation management. In this way, the power management and temperature control of the server motherboard can be realized. [0003] The data reading and writing of the PECI bus includes instructions such ...
