ICS/OT Cybersecurity Fundamentals
ICS/OT Cybersecurity Fundamentals
Understand the Systems. Assess the Risks. Apply the Right Defenses.
Industrial control systems were designed to run reliably for decades. They were not designed to defend themselves against modern adversaries. ICS/OT Cybersecurity Fundamentals gives engineers, technicians, and IT professionals a clear, practical path from understanding what these systems are to knowing how to protect them.
What This Book Delivers
- ICS foundations first. Understand what PLCs, HMIs, SCADA systems, and DCS platforms actually do before any security concepts are introduced.
- The IEC 62443 framework, applied. Zone and conduit design, security levels, and the risk assessment workflow that the standard defines.
- Real threats, real incidents. Attack reconstructions from Stuxnet to Colonial Pipeline, explained in terms that make the defensive lessons stick.
- OT-specific defenses. Passive monitoring, network segmentation, remote access controls, and vendor evaluation methods that fit operational constraints.
- Risk language that lands. Communicate risk clearly to management, auditors, and IT teams using the vocabulary they expect.
Who It's For
- OT engineers and automation technicians who are being asked to take on cybersecurity responsibilities.
- IT security professionals transitioning into ICS or OT environments.
- Anyone who needs to understand ICS cybersecurity at a working level before applying it on the job.
How It's Structured
- Chapters 1-3: ICS foundations — what the systems are, how they work, and how they communicate.
- Chapters 4-13: Cybersecurity fundamentals — threats, defenses, risk assessment, and the IEC 62443 framework.
- Each chapter builds on the last. No concept is introduced before the foundation for it exists.
ICS/OT Cybersecurity Fundamentals — Security Built for Industrial Systems
Industrial control systems cannot be secured like ordinary IT. A forced reboot, aggressive scan, or incompatible patch can interrupt production and create real safety consequences. Effective OT security begins with understanding the systems, constraints, and risks unique to industrial environments.
This course gives IT professionals, engineers, operators, and security practitioners a practical foundation in ICS threats, zone and conduit design, risk assessment, passive asset visibility, and vendor evaluation. You will learn how IEC 62443, NIST CSF, and MITRE ATT&CK for ICS apply where availability and safety come first.
Eight reconstructed incidents—including Stuxnet, Triton, Ukraine 2015, Colonial Pipeline, and PIPEDREAM—show how attackers move through OT environments, what they target, and which defenses could have changed the outcome.
Watch the course preview, then build the vocabulary, frameworks, and judgment needed to take credible first steps in ICS/OT cybersecurity.

Build an ICS/OT cybersecurity foundation that fits the real environment
Standard IT controls can disrupt the industrial systems they are meant to protect. Learn how to assess OT risk, design zones and conduits, apply IEC 62443 security levels, use MITRE ATT&CK for ICS, and establish passive asset visibility without risking production. Eight reconstructed incidents connect attacker techniques to the controls that failed, giving you the vocabulary and judgment to make credible security decisions from day one.
