OT/ICS Security Foundations and Professional Prep

Critical infrastructure, manufacturing plants, and utility grids rely on Operational Technology (OT) and Industrial Control Systems (ICS) that require specialized security measures. This text-based course guides you through the foundational concepts and modern practices needed to secure these vital environments. You will transition from understanding basic IT security to grasping the unique, high-availability demands of OT/ICS security, preparing you with the core knowledge required for professional security roles in industrial environments. What you'll learn: Understand the core differences between traditional IT security and OT/ICS environments; Identify common ICS components including PLCs, RTUs, SCADA systems, and HMIs; Analyze the modern threat landscape targeting industrial control networks and critical infrastructure; Apply foundational network segmentation techniques and the Purdue Model for secure architecture; Implement zero-trust security concepts and secure remote access protocols for industrial sites; Practice incident response planning and vulnerability management tailored for high-availability systems. The course begins with essential terminology, foundational definitions, and architectural models before moving into practical security controls, threat analysis, and risk management strategies. You will read through clear explanations, real-world scenarios, and structured text exercises designed to reinforce your learning. This course is designed for IT professionals, entry-level security analysts, and engineering students who want to break into industrial cybersecurity. No prior experience with OT or ICS hardware is required. Start reading today to build a strong foundation in protecting the physical systems that power our world.
