Industry Background

Fig. 1: Overview of cyber attacks affecting the critical manufacturing sector

As the Industrial IoT (IIoT) continues to expand, more and more devices are being connected to networks. This trend is seeing networks transitioning from closed networks to enterprise IT networks that are accessible over the public Internet. While this trend is enhancing operational efficiency, it is unfortunately causing asset owners to become increasingly concerned about the dangers posed by cybersecurity threats. The asset owners’ concerns are justified. A recent report released by the Industrial Control Systems Cybersecurity Emergency Response Team (ICS-CERT) calculated that investigators responded to 392 incidents in 2016 in the U.S., compared to 295 the previous year regarding cyber-attacks on infrastructure. The growth rate of product vulnerability incidents was 32.88% from 2015 to 2016. It is therefore unsurprising that asset owners are increasingly requiring cybersecurity solutions to allow them to build secure systems for industrial applications.
