System security credible monitoring method, system and device

The invention provides a system security credible monitoring method, system and device, and belongs to the technical field of computers. The system security credible monitoring method is applied to a credible service platform, and comprises the following steps: acquiring credible initial reference values of a plurality of system processes, and constructing a dynamic measurement reference library based on the credible initial reference values of the plurality of system processes; and constructing a security operation strategy based on the dynamic measurement reference library, and deploying the security operation strategy to the system, so that the system acquires the dynamic measurement value of the active process in real time, and performs dynamic measurement verification on the active process based on the dynamic measurement value of the active process and the security operation strategy to generate a real-time monitoring result. According to the method and the device, the security monitoring of the process
