This chapter covers the essential dimensions of IIoT endpoint security. It establishes an working definition of IIoT endpoints and discusses various use-case specific considerations for securing them. A real-world case study is cited to illustrate the vulnerabilities of typical industrial device endpoints. In this chapter the reader also finds an elaborate treatment of the endpoint security enabler technologies which spans the silicon, software and processes. The increasing use of machine learning and the importance of testing and certifications using industry standards have also been discussed in this chapter.
Chapter 5, Securing Connectivity and Communications, focuses on the next level of the 4-tier IIoT security model.
