OT Cybersecurity & Resilience for Industrial Environments

Build OT cybersecurity skills through IT–OT distinctions, Purdue Model, asset visibility, modern ICS architecture

What you’ll learn
✓ Explain the fundamental differences between IT and OT systems, including priorities, constraints, and risk models.
✓ Describe the Purdue Model and how it structures industrial networks and security zones.
✓ Understand the role of asset inventory and network visibility in OT cybersecurity programs.
✓ Recognize common ICS threats, attacker motivations, and real‑world industrial cyber incidents.
✓ Identify key components of modern OT and ICS architectures, including segmentation, DMZs, and industrial protocol
✓ Apply foundational OT security concepts to improve resilience in industrial environments

Requirements
● Basic understanding of computers and networking
● No prior OT or ICS experience required
● Familiarity with general cybersecurity concepts is helpful but optional
● Interest in industrial systems, critical infrastructure, or cybersecurity
● No special software or tools needed

Description
Industrial environments are facing unprecedented cyber risks. As IT and OT systems converge, organizations must strengthen visibility, architecture, and resilience across their operational technology landscape. This course provides a clear, structured introduction to the core concepts every OT cybersecurity professional must understand.

You’ll explore the key differences between IT and OT systems, including how priorities like safety and availability shape OT security strategies. We’ll dive into the Purdue Enterprise Reference Architecture to understand how industrial networks are segmented and secured, and why this model remains foundational in ICS environments.

Next, we’ll examine asset inventory and network visibility — two critical pillars of any OT cybersecurity program. You’ll learn how passive discovery tools work, why active scanning can be risky, and how to build a living inventory of industrial assets.

The course also covers modern OT/ICS architectures, including segmentation, DMZs, and common industrial protocols like Modbus. Finally, we’ll explore the evolving ICS threat landscape, from ransomware and insider threats to nation-state attacks and malware like Stuxnet and Triton.

Whether you’re transitioning from IT, entering the OT security field, or strengthening your industrial cybersecurity knowledge, this course gives you the practical, real-world grounding needed to operate confidently in industrial environments. Please join me.

Who this course is for
