A technical deep dive into Modbus, BACNet and OPC UA. Build a lab, inspect traffic, and simulate protocol-level attack
What you'll learn
Understand Operational Technology Fundamentals
Dissect common industrial protocols, understanding their frame structure, and communication flow packet-by-packet.
Create a safe, simulated ICS environment on your own computer to practice packet analysis and security testing.
Learn to capture live OT traffic in Wireshark and simulate realistic attack scenarios, such as the "Rogue Setpoint".
Requirements
A computer (Windows, Mac, or Linux) capable of running virtualization software like VirtualBox or VMWare Workstation.
Basic understanding of networking (IP addresses, Ports, TCP/UDP).
No physical PLCs, HVACs or industrial hardware required.
Familiarity with Operational Technology and Industrial Control Systems
Description
This course contains the use of artificial intelligence. For more details, see the note at the end.Bridge the gap between IT Security and Critical Infrastructure.Operational Technology (OT) and Industrial Control Systems (ICS) manage the physical world around us—from manufacturing lines to energy grids. For many security professionals and network engineers, these systems remain a "black box," operating on legacy protocols that differ significantly from standard IT networks.Offensive Security for OT & ICS Protocols is designed to demystify these systems through a practical, hands-on approach.The core focus is on the technical reality of how industrial devices communicate. We believe that to truly secure an industrial network, you must understand exactly what is happening inside the wire.What We Cover in This Course?We begin by establishing a strong foundation. You will learn why OT security is distinct from IT security, exploring the unique constraints of industrial environments. We cover the Purdue Model for segmentation and introduce the "Big Three" protocols that dominate the industry.Learning OT security traditionally required expensive hardware. In this course, we guide you through setting up a Virtual Industrial Lab on your own computer. You will deploy simulated devices and establish a functional network that mimics a real-world facility.A Living CourseThe world of OT is vast. This course is designed as an evolving resource.Current Focus: We launch with a comprehensive focus on Modbus.Future Roadmap: We are actively developing modules for BACnet and OPC UA. As an enrolled student, you are part of this journey, and these updates will be added to the curriculum to expand your knowledge base.Who Should Take This Course? This course is written for the curious. Whether you are a Penetration Tester looking to expand into OT, an OT Engineer encountering industrial devices, or an enthusiast wanting to understand how industrial systems communicate, this course provides the technical groundwork you need.Legal Disclaimer: This course is for educational purposes only. All demonstrations are performed in a controlled, virtual lab environment created specifically for this course. The skills taught here are intended to help you identify vulnerabilities and secure industrial systems.Note: All course content is personally researched, scripted, and structured by the instructor. To ensure clear, consistent, and noise-free audio, the narration is delivered by professional AI voice synthesis.
Who this course is for
Cybersecurity professionals pivoting to OT/ICS
Red Team operators
OT engineers interested in security
Ethical Hackers & Pentesters
