The State of Cybersecurity in Smart Manufacturing Systems: A Systematic Review

With the advent of the so-called 4th Industrial Revolution, personified in the globally commented Industry 4.0, there is a change in progress in manufacturing systems, provided by the development of communication and information technologies, adding an intelligence component in manufacturing plants, through the possibility connectivity and interaction throughout the production chain (intelligent manufacturing systems or cyber-physical systems). However, this new paradigm has an extremely sensitive component, which is the question of the security of the data that is transferred and of the production processes itself. Due to this premise, this article proposed to bring, through a systematic literature review, research about the academic works related to security in these new manufacturing structures (smart manufacturing systems), analyzing which strategies, methodologies, techniques, and technologies have currently used to learn about their vulnerabilities and mitigate possible attacks.
