As IT and operational technology (OT) network lines continue to blur in the rapidly digitalized industrial sector, new vulnerabilities and threats imperil conventional OT security measures that once isolated and guarded physical processes from cyberattacks.
Two new separate sets of research released this month underscore real, hidden dangers to physical operations in today’s OT networks from wireless devices, cloud-based applications, and nested networks of programmable logic controllers (PLCs) — effectively further dispelling conventional wisdom about the security of network segmentation as well as third-party connections to the network.
