The invention discloses a process running method which comprises the following steps: receiving a process starting request, and executing an executable file of a target process in a kernel according to the process starting request to obtain first running function data supporting the target process to run in the kernel; migrating the first operation function data to a function security partition to obtain second operation function data, the function security partition and the kernel being located in the same privilege layer; and running the target process in the function security partition based on the second running function data. According to the scheme, the function security partition and the kernel are both located in the kernel layer, so that when the process runs, the service of the kernel layer can be called without switching from a user layer to the kernel layer, the performance overhead brought by privilege layer switching is reduced, and the performance of the processor and the performance of the ter
