Udemy – OT Cybersecurity & Resilience for Industrial Environments

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.
