The Case for Zero-Trust Access for the Industrial Internet of Things

Explore how IIoT-OT integration boosts efficiency but increases cybersecurity risks in unprotected systems. In recent years, the convergence of the Industrial Internet of Things (IIoT) with Industrial Control Systems (ICS) and other Operational Technology (OT) has accelerated, driven by the need for greater operational efficiency. While this integration improves visibility and data access by using IT protocols like Ethernet and MODBUS/TCP, it also introduces cybersecurity risks, as many OT systems lack modern protections such as patching, encryption, and access controls.
