This work aims to study the importance of the pedagogical use and the integration of computer simulation software targeting the cybersecurity of critical infrastructures remote control systems within the educational process, teaching and learning, and also within the professional sector use during trainings. Simulators usage contributes in the enhancement of teaching and trainings quality, and help providing clear visibility about the studied systems, that are inaccessible by the large public and especially students of cyber-security field, and critical infrastructures managers having low budget allowed for cyber-security purpose, throughout providing a low cost solution using Domain specific language (DSL) for system modeling in order to ensure clear awareness about critical infrastructures cyber-security, either during practical work session classes or employees trainings.
