ABSTRACT
Digital manufacturing activities in the Industry 4.0 era are independent of time, distance, and place of operation due to the incorporation of information and communication technologies (ICT), such as cyber physical systems (CPS), internet of things (IoT), and internet of services. These activities encompass the entire chain of the digital manufacturing thread, which make it extremely vulnerable to cyber-attacks and further risks to cyber security. One of the key challenges in meeting the growing implementation of digital manufacturing processes is to ensure cyber security in intelligent manufacturing industries. A recent report by Roland Berger shows that the manufacturing industry is the sector most affected in terms of facing cyber-attacks. The main challenges in digital manufacturing and its countermeasures are influenced by cyber security considerations in product design, materials requirement planning, advanced manufacturing, process automation, and intelligent machining.
In this context, this chapter discusses details about potential cyber-attacks in the design and manufacturing phases, as well as the modus operandi of attacks and the consequences they could have on digital manufacturing systems. In addition, various cyber-attacks on digital manufacturing have been analyzed and mitigation approaches have been suggested to achieve cyber security objectives, such as confidentiality, integrity, and availability. It also identifies various cyber security challenges that exist in the manufacturing sector and gives future research directions, as well as proposed recommendations.
