ICS Security Foundations: Control Systems, Defence in Depth and the 62443 Requirements
The ground floor of industrial cyber security, taught through the systems themselves: what a DCS, PLC, SCADA, BACS and safety system actually do, the Purdue model, why OT is not IT, how industrial attacks unfold, defence in depth and a layered architecture, then the seven ISA/IEC 62443 foundational requirements one at a time, asset registers, segmentation, discovery, IDS and IPS, secure remote access, SIEM and endpoint protection.

What you will learn
Name the control systems in a plant and say what each one runs, place any device on a Purdue level, explain why an IT security policy cannot be applied unchanged to OT, describe how an industrial attack unfolds and what it costs, build a layered defence, apply each of the seven ISA/IEC 62443 foundational requirements to a real asset, keep an asset register, segment a network, discover devices safely, and choose between IDS, IPS, secure remote access, SIEM and endpoint controls.
- Tell a DCS, PLC, SCADA, BACS and safety system apart
- Place any device on a Purdue level and defend the choice
- Explain why an IT security policy cannot be applied to a plant
- Build a layered defence and pick compensating controls
- Apply the seven ISA/IEC 62443 foundational requirements
- Keep an asset register, segment a network and discover devices safely

Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.
- Questions answered in the context of the module you are on
- The same engineers who teach the AEP programme
- Career tools, CV help and public job listings included
- Your progress and notes stay in your account for good

Common questions
Is this the same as the ISA/IEC 62443 course?
No, and it is the one to take first. This course teaches the systems and the seven foundational requirements from the ground up. The 62443 course goes on to security levels, risk assessment, governance and certification preparation.
Do I need a security background?
None. It starts from what a PLC is.
Do I need any software or hardware?
Neither. Every module is diagrams and worked examples you can follow on paper.
Does it prepare me for a certification?
It is the groundwork rather than exam preparation. Take the ISA/IEC 62443 course after this one for the certification material.
