The current state of the cyber ecosystem is a precarious one. The perimeters have become blurred, and as the capabilities and connectivity of cyber devices have grown exponentially, so have cyber intrusions from sophisticated malware to both Information Technology (IT) and Operational Technology (OT) Industrial Control Systems (ICS), and SCADA networks. The threat is even more amplified as those networks are converging.
According to PMMI Business Intelligence’s “2021 Cybersecurity: Assess Your Risk,” report from, Information Technology (IT) attacks “specifically target the enterprise IT systems at a manufacturer, seeking to gain entry through vectors such as email, a CRM system, or an ERP program, which can span across an operation.” Operational Technology (OT) attacks “are designed to exploit the systems that are directly on the plant floor. An OT attack can originate through vectors such as individual sensors on the production line, SCADA/HMI panels, or even unsecured PLCs.” Cybersecurity 101: The Difference Between IT and OT Attacks | OEM Magazine
But in our increasingly hyper-connected internet environments, most physical security systems have become tethered to IT networks and evolving cloud infrastructure. The trend of integration of Industrial hardware and software combined with growing networked IT sensors is redefining the surface attack opportunities for hackers across all digital infrastructures.
The IT OT Convergence Supply Chain
Protecting the fusion of IT/OT networks from cyber-attacks is an urgent challenge that requires orchestration. They all have unique operational frameworks, access points, and a variety of legacy systems and are intertwined with varying regulation and compliance protocols. And a lack of trained skilled workforce is a continual issue in IT, OT and ISC cybersecurity.
