Operational Technology Security
Operational Technology (OT) Security is a specialized field focused on protecting industrial control systems (ICS), supervisory control and data acquisition (SCADA) systems, and other hardware and software that monitor and control physical processes in critical infrastructure sectors like energy, manufacturing, and transportation. It involves securing devices such as programmable logic controllers (PLCs), human-machine interfaces (HMIs), and sensors from cyber threats that could disrupt operations, cause safety hazards, or lead to environmental damage. Unlike traditional IT security, OT security prioritizes availability and safety over confidentiality, as system failures can have severe real-world consequences.
Developers should learn OT security when working in industries like utilities, oil and gas, or manufacturing, where cyber-physical systems are integral to operations, to prevent incidents like the Stuxnet attack or ransomware targeting industrial facilities. It is crucial for roles involving IoT in industrial settings, smart grid implementations, or automation projects, as it helps ensure compliance with standards like NIST SP 800-82 and IEC 62443. Understanding OT security enables developers to design resilient systems that protect against threats while maintaining operational continuity and safety.
