Causes and Consequences of IT and OT Network Convergence

A critical element of today’s digital transformation involves connecting OT or (Operational Technology) systems to the IT infrastructure and even the internet. There are many reasons for this. Cloud-based services, for example, allow for more efficient and reliable monitoring of remote devices and sensors.

Tying manufacturing floors to global market data increases efficiencies and profitability through such things as just-in-time inventory and flexible, on-demand production. As a result, OT systems and data are increasingly being transited or tunneled over corporate or public networks, are incorporating traditional IT devices, and are beginning to leverage common internet protocols. This increase in connectivity and use of common hardware is expanding the potential OT attack surface.
