This academic work was born as an evolution of the pre-existing BAT-MAN project developed in the last two years by the company Brain Technologies. From it, we took the basic concepts in order to apply them into the Cyber-physical security field. The goal in fact is to use an observer-based approach to be able to successfully detect an attack and, above all, identify the kind of attack the system is receiving. Different analysis and tests have been performed, so that only the most significant are presented in this work. The first part presents a brief dissertation of the cyberphysical security field in general.
