Power Internet of Things security component virtualization construction method and system

The invention discloses a power Internet of Things security component virtualization construction method and system. The method comprises the steps of obtaining a current application environment and a current security demand of a to-be-deployed position and a core basic mirror image corresponding to a minimum operation environment of a security component; based on the current application environment and the current security demand, screening security component mirror images from a preset security component mirror image library to form a security component mirror image set, wherein the preset security component mirror image library is used for storing mapping rules among the application environment, the security demand and the security components; and constructing a virtualized security component based on the core base mirror image and the security component mirror image set. According to the invention, through presetting the mapping rule among the application environment, the security requirement and the secu
