Towards a secure industrial internet of things

Abstract

The Industrial Internet of Things (IIoT), being one of the underlying and enabling technologies of the Industry 4.0 initiative, brings about expectations for unprecedented value creation opportunities in industry. Unfortunately, these do not come without a price; in this case the price to pay is the increased vulnerabilities, the increased threats and the increased attack surface that result when industrial systems originally designed with little or no cybersecurity in mind connect to the Internet. Consequently, the cybersecurity of the IIoT becomes of paramount importance. Research has started focusing on this area, as well as on the related areas of cyber-physical systems security and industrial network security, but a multitude of issues still remain to be addressed. In this chapter, we review recent research results in the area of IIoT security, with an eye towards identifying trends on one hand and areas where research seems to lag behind on the other, by classifying research results using the security lifecycle model of the National Institute of Standards and Technology (NIST) framework for improving the cybersecurity of critical infrastructures. © Springer Nature Switzerland AG 2019.
