What is the difference between IT cybersecurity and OT (Operational Technology) cybersecurity?

The primary difference lies in their priorities: IT cybersecurity prioritizes confidentiality, integrity, and availability (CIA), while OT cybersecurity prioritizes availability, integrity, and then confidentiality (AIC). OT systems, like those in manufacturing or power grids, are critical for continuous operations, so downtime is far more impactful than data breaches. Attacks on OT can lead to physical damage, production halts, or even loss of life. In Bangalore, companies like Schneider Electric or ABB, which deal with industrial control systems, heavily invest in OT security, often using specialized protocols and isolated networks, distinct from their corporate IT infrastructure. Interviewers at these firms will expect you to understand this fundamental distinction.
