What Is OT Cybersecurity?
Summary: Dragos and the SANS Institute describe OT cybersecurity as the practice of protecting the industrial assets and processes that run on OT networks, the systems that control and monitor physical devices in sectors such as manufacturing, energy, water, and transportation. The article states that industrial control systems are a major subset of operational technology, and that OT security differs from IT security in goals, challenges, and requirements even as IT/OT convergence makes the two more interconnected.
Bottom line: The distinction is concrete: IT security protects data and systems that store and transmit information, while OT security protects the physical processes behind critical infrastructure - and the article notes that convergence is driven by digital transformation, business integration, and the cyber threat landscape, so the boundary a security leader relies on is already eroding.
