Industrial Cybersecurity Essentials
Course Description
When we think of cybersecurity, we usually think of computers, servers, and data. But what about the systems that run our power grids, water treatment plants, factories, and oil refineries? These industrial control systems (ICS) and operational technology (OT) environments have unique security challenges—and a breach can have real-world physical consequences.
This free course from Cisco Networking Academy introduces you to the specialized field of industrial cybersecurity. You'll learn the difference between IT and OT environments, common threats to industrial systems, risk management strategies, and security best practices for protecting critical infrastructure. The course covers industry standards (like ISA/IEC 62443), network segmentation (the Purdue Model), and incident response for industrial environments.
This free, self-paced course takes about 15 hours to complete and includes interactive modules, case studies (including real-world attacks like Stuxnet and Triton), and a final exam. Upon completion, you'll earn an official Cisco digital badge. It's ideal for IT professionals moving into OT security, industrial automation engineers, and anyone interested in protecting critical infrastructure.

Course Prerequisites
Technical: Basic understanding of networking (IP addresses, TCP/IP, routing) and general cybersecurity concepts. Some familiarity with industrial environments is helpful but not required.
Recommended prior courses: Networking Basics and Introduction to Cybersecurity (Cisco) or equivalent knowledge.
Who should take this: IT security professionals transitioning to OT security, industrial automation engineers, control system technicians, critical infrastructure operators, and anyone interested in protecting power grids, water systems, factories, and pipelines.
User Reviews
"I've worked in industrial automation for years, but I never really understood the cybersecurity side. This course was the perfect bridge. It explains the unique challenges of OT security without assuming you're an IT expert. The case studies (Stuxnet, Triton) were fascinating and scary. I've already applied the Purdue Model concepts to our factory network. Highly recommended."
"As an IT security professional, I thought I knew cybersecurity. Then I tried to apply my knowledge to our company's manufacturing floor, and nothing worked the way I expected. This course taught me why. OT environments are fundamentally different: legacy systems, safety constraints, specialized protocols. The module on incident response for OT was particularly valuable. A must for any IT person moving into industrial security."
"Excellent content, but be aware: this is a conceptual course, not a hands-on lab course. You won't be configuring firewalls or analyzing Modbus traffic. But for understanding the OT threat landscape, risk management, and industry standards, it's fantastic. The Cisco badge is a legitimate credential that helped me get an interview for an OT security role."

💡 Final Thoughts
Industrial cybersecurity is one of the fastest-growing and most critical fields in security. A cyberattack on a power grid or water treatment plant isn't just about data—it's about public safety and national security. This Cisco course gives you a solid foundation in the unique challenges of protecting operational technology (OT). You'll learn the difference between IT and OT, understand industrial protocols and architectures, study real-world attacks, and learn risk management strategies based on industry standards like ISA/IEC 62443. It's not a hands-on technical course, but it's the perfect starting point for anyone wanting to enter this high-demand field. And the Cisco badge is a legitimate credential. If you're in IT or industrial automation, this course will open your eyes to a whole new world of security challenges and opportunities.
