AN EXECUTIVE ’ S GUIDE TO INDUSTRIAL CYBERSECURITY
Industrial control systems ( ICS ) and operational technology ( OT ) are the systems and networks that control physical processes across the enterprise . ICS / OT systems bridge the gap from the software world to the physical world .
Prevalent in industrial settings , ICS / OT systems are the ones that control physical processes including electricity generation , oil and gas refining and pipelines , automated mining rigs , and factory automation . But OT is actually present in a much broader range of use cases than that . It ’ s crucial for operating warehousing and distribution systems , transportation lines , and even HVAC systems in data centers , large buildings , and campuses . In short , OT is to physical systems what IT is to business systems
Often OT and IT share similar technologies , running on similar operating systems , network connections , and digital architectures . But OT is not a direct one-to-one equivalent to its IT counterpart . OT working environments are very different than IT and are tied to the core function of the business : producing electricity , manufacturing products , transporting products , and keeping facilities open and functional . p
