Server security encryption method and device based on memory space, equipment and medium

The invention belongs to the technical field of service security, and particularly provides a server security encryption method and device based on a memory space, equipment and a medium, and the method comprises the following steps: after a server is powered on, writing a security mechanism code into the memory space; starting the running security mechanism code to obtain server configuration information, and recording and storing the obtained configuration information as an original comparison information value; when the server is invaded, the encrypted key is automatically compared; when the secret keys are not matched, the server is automatically triggered to be locked; when the secret keys are matched, receiving modification on the configuration information of the server, and recording and storing the modified new configuration information as a new comparison information value; when the new comparison information value is different from the original comparison information value, prompting that the server
