Sources: 8. Developments: 2. The manufacturing sector is undergoing a digital transformation through Industry 4.0, utilizing the Internet of Things (IoT) to connect machines, production assets, and supply chains. This convergence of Information Technology (IT) and Operational Technology (OT) enables real-time data collection and predictive maintenance, with the global IoT manufacturing market projected to grow significantly through 2031. However, this increased connectivity introduces substantial cybersecurity risks by expanding the attack surface. A primary concern is the integration of modern IT infrastructure with legacy OT systems, which often lack built-in security mechanisms. Experts highlight a tendency in the industrial sector to avoid updating these legacy systems to prevent operational downtime, a practice that results in “accumulating digital debt and silent security risks.” While IT systems have seen progressive security improvements, industrial technologies are frequently managed under outdated logic designed for isolated environments, leaving them vulnerable as they become interconnected. ## Timeline ### 2026-10-07: Industrial cybersecurity faces risks from IT-OT convergence The integration of IT and OT in Industry 4.0 is expanding the cyberattack surface for manufacturers, creating risks as legacy industrial systems become increasingly connected. 2 sources. https://clstr.news/cluster/industrial-cybersecurity-faces-risks-from-it-ot-convergence ### 2026-09-22: IoT and cybersecurity trends in smart manufacturing Manufacturing is shifting toward connected, data-driven operations via IoT, driving market growth but increasing cybersecurity risks due to the convergence of IT and legacy operational technology. 6 sources. https://clstr.news/cluster/iot-and-cybersecurity-trends-in-smart-manufacturing --- Cite as: Cybersecurity risks in smart manufacturing.
