Introduction to ICS and SCADA Security: Protecting Operational Technology

Industrial control systems (ICS) and operational technology (OT) power our critical infrastructure, but they are increasingly targeted by modern cyber threats. Securing these environments requires a specialized mindset that prioritizes physical safety and operational uptime alongside data security. This text-only course provides a comprehensive foundation in ICS/SCADA security, taking you from core terminology to practical defense strategies. You will understand how industrial networks operate, how they differ from traditional IT environments, and how to implement modern security frameworks to protect critical assets. What you'll learn: Understand foundational ICS/SCADA concepts, including the Purdue Model and common industrial protocols; Analyze the modern OT threat landscape and identify common vulnerabilities in industrial environments; Apply network segmentation and zero-trust principles to isolate and protect critical control systems; Develop basic incident response and resilience strategies tailored for continuous industrial operations; Implement essential security controls without disrupting physical processes or safety systems. The course begins with essential definitions and architectural baselines before exploring threat vectors, defensive controls, and risk management strategies. You will progress through detailed written explanations, real-world scenarios, and practical review exercises to solidify your understanding. This course is designed for IT professionals transitioning to OT, plant operators curious about cybersecurity, and beginners looking to enter the field of industrial security, with no prior cybersecurity experience required.
