Operational technology cybersecurity applies to control systems, industrial networks, sensors and devices used in power, water, manufacturing and other physical operations. Security decisions must account for safety, uptime and equipment lifecycles as well as ordinary information protection.
Operational systems can be difficult to patch or take offline, and exposure may arise through remote access or connected business networks. Segmentation, asset inventory, controlled access and coordinated incident planning are central defenses.

Operational technology cybersecurity protects computer systems that control physical equipment and industrial processes. Security must protect people, uptime and machinery as well as information.
For example, a water plant can separate pump controllers from ordinary office networks and tightly control remote access. Updates and incident plans need care because taking a physical process offline may itself create danger.
How is OT cybersecurity different from ordinary IT security?
Operational technology controls physical processes, so safety, availability and equipment constraints can make standard patching and response practices unsuitable.
Why are remote connections to operational systems risky?
Remote access can create a path from internet-facing or business networks into physical operations if authentication, segmentation and monitoring are weak.
