OT Cybersecurity Frequently Asked Questions
OT Cybersecurity is the practice of protecting Operational technology (OT) from cyber threats. OT refers to the broad range of devices, hardware and software that monitors and controls physical processes or assets. This can include industrial control systems, building management systems, fire control systems and field devices like sensors and valves, as well as assets such as manufacturing equipment, boilers and chillers.
OT has many characteristics that differ from traditional IT systems, with the main differences being the purpose and priorities of the systems. Let’s compare an Engineering Workstation (EWS) to a normal business use laptop. While they may both use a Microsoft Windows operating system, an EWS could be critical to the operations of a manufacturing line, processing plant, or safety system. The EWS device often cannot be simply restarted for a new patch like a traditional business machine used for word processing or email. Instead, updating these systems requires a careful plan and patch management policy, including validation with system vendors, a recorded baseline, and a rollback plan to protect business continuity and maintain safety.
Any industry using OT systems should have a dedicated strategy to protect these assets in their cybersecurity program. Industries considered “critical infrastructure” by governments and regulators, such as energy, water, transportation, healthcare, and manufacturing, may also be required to comply with specific OT security regulations.
The threats facing OT environments range widely in both sophistication and impact from nation states targeting critical infrastructure, hacktivists with ideological goals, insider threats from employees, supply chain attacks and malware pivoting from IT networks. In The 2025 Honeywell Cyber Threat Report, we found that ransomware attacks targeting industrial operators jumped 46% in the first quarter of 2025.
Depending on the countries and industries in which your organizations operates, there may be regulations that require reporting of OT cybersecurity breaches within a specific timeframe.
