In their latest article for Manufacturing Today India, Koushik Nath, Vice President and CISO, ITC Ltd, and  Raman Kartik Iyer, Vice President & Global Head – Supply Chain and Industry 4.0, ITC Infotech, examine the rising importance of building a sustainable OT cybersecurity program in the connected manufacturing era.

They highlight how the convergence of IT and OT has created new cyber risks, citing lessons from recent high-profile global attacks, and explain why traditional security approaches no longer suffice in the Industry 4.0 era. The article presents a multi-layered roadmap for manufacturers- spanning asset hardening, network segmentation, supply chain risk management, incident response, and security-by-design–while emphasizing the need for a human-centric approach that fosters collaboration across IT, OT, and business teams.

It reinforces that resilient OT cybersecurity is not just protection- it is a foundation for innovation, compliance, and operational continuity in modern manufacturing.
