This paper discusses the risks of industrial security services. Moreover, the authors consider future automation scenarios as well as the major concepts involved in industrial security services.

As a survey, the paper describes the major risks in Industry 4.0 and “shows how managed industrial security services can contribute to stabilize the industrial system.” The authors list cybersecurity threats, including “targeted attack to automation system, attack via Internet on decentralized control system, unauthorized access from office to production network.” These threats already exist and practically affect the stability of industrial services. In the countermeasure part, the authors mainly propose the automation and its protection, which has been rapidly developed in recent years. Finally, the authors discuss industrial security services from operation and management levels.

The paper provides a high-level roadmap for industrial security services. Its concepts and content are very practical. I recommend it to managers and engineers in this area.
