Groundbreaking technologies, like Artificial Intelligence (AI), digital twins, and robotics, are continually pushing organisations in the industrial sector toward further digital transformation. Termed Industry 4.0, this trend is driving increasing technology investments, predicted to grow from US$41 billion in 2022 to nearly US$200 billion by 2030.

At that point, there will be an estimated 1.2 billion connected machines used in production systems. As is the new case of any technology, the rapid evolution and proliferation of IoT in the industrial sector bring with it serious security concerns. As is often the case, IoT security investment tends to come only later, after organisations have experienced exploitation of their new connected systems.

This whitepaper presents an identity-based approach to securing IoT devices in industrial contexts using Public Key Infrastructure (PKI) as a critical component. To do this, industrial players must look at the key drivers creating a more internet-connected industrial market, such as current primary internet networking approaches and connectivity needs.

It also breaks down the current challenges that other security approaches don’t adequately address, such as air-gapped and offline systems, decade-long lifespans, and the prevalence of highly constrained and low-compute devices. You’ll also discover the tangible benefits of implementing PKI security systems, from prioritising automation to encouraging custom development.
