IIoT and OT security
Industrial networks, Node-RED for data and dashboards, and ISA/IEC 62443 to keep the plant safe once it is connected.
Step 1Industrial networksIntermediateIndustrial Communication: Serial, Fieldbus, Ethernet, Modbus, PROFINET and OPC UA
Every network a PLC engineer meets, from RS-485 and Modbus to PROFINET, EtherNet/IP and OPC UA, with hands-on PLC-to-PLC and Modbus configuration in TIA Portal.
- Explain the OSI model, Ethernet, IP addressing and subnets
- Wire RS-485 and read a Modbus frame, function code and address
- Place PROFIBUS DP and PA, DeviceNet, AS-i and IO-Link
Step 2IIoTBeginnerNode-RED for Industrial IoT
The open-source glue of Industry 4.0: Node-RED fundamentals, core nodes and JSON, dashboards, Raspberry Pi and industrial hardware, Modbus RTU and TCP, Siemens S7-1500 with OPC UA and the IOT2050, MQTT, databases and email, APIs and cloud, Node-RED inside PLCs, and OEE and MES thinking.
- Install Node-RED and master the core nodes and JSON
- Build dashboards and run Node-RED on a Pi or gateway
- Read and write Modbus RTU and TCP devices and PLCs
Step 3CybersecurityIntermediateOT and ICS Cybersecurity with ISA/IEC 62443
Defensive cybersecurity for plants: ICS/OT fundamentals and threats, protocols, the Purdue model, zones and conduits, secure architecture, the ISA/IEC 62443 series, security levels, risk assessment, asset inventory, vulnerability management, incident response, governance, implementation, an introduction to authorised OT testing and certification mock tests.
- Explain OT versus IT security and the threat landscape
- Map plants with the Purdue model into zones and conduits
- Apply ISA/IEC 62443 parts, roles and security levels
How the path works
Join the path and every course is added to your account at once, each with its own progress, notes, quizzes and final. Take them in the order shown: each assumes the one before. Module quizzes are five plain questions and the final is twenty, pass mark 50%, with unlimited retries, so the assessment checks that you followed the lessons rather than testing exam nerves.
Questions
- Is the IIoT and OT security free?
- Yes. Every course in the path is free in full: lessons, notes, practice tasks and assessments. Joining the path adds all of them to your account in one step. The only paid item is the optional EDWartens Certificate of Completion for each course.
- In what order should I take the courses?
- In the order listed: each course assumes the one before it. Every course keeps its own progress, quizzes and certificate, so you can also take one on its own.
- Do I get one certificate for the whole path?
- Certificates are per course, issued when you pass that course's final assessment and bought only if you want them. Finishing every course in a path gives you one certificate per course.
