OT Security (Operational Technology Security)
Definition
OT security covers the protection of Operational Technology: hardware and software controlling physical processes in factories, power plants, water utilities, and other critical infrastructure.
OT environments (SCADA, PLC, DCS) are designed for reliability and safety, not cybersecurity. Many OT systems run on outdated operating systems and cannot be easily patched.
NIS2 mandates critical infrastructure operators to implement OT security measures.
