Ch 2 — Automation

Manual vs. automated process, sensors & actuators, logic control, tags & setpoints, data historian, safety instrumented systems.

Ch 3 — Distributed Control Systems

Functional levels, controllers, marshalling cabinet, PID, HMI, engineering workstations.

Ch 4 — SCADA vs. DCS

SCADA server, PLC, RTU/PAC, IED, industrial PC, IEC 61131 languages (IL, ST, SFC, FBD, LLD), alarms.

Ch 5 — OT terminology & classification

IT vs. OT, air-gap myth, IT/OT convergence.

Part 2 Communications

Ch 6 — OT network architecture

Purdue model, DMZ, reading architecture diagrams, OOB networks, data diodes, SPAN, TAPs, virtualization, NAT, performance, form factor, IP ratings, topologies & protocols.

Ch 7 — IoT / IIoT

IoT World Forum reference model, challenges, cyber risk, MQTT, 5G cybersecurity.

Ch 8 — IT/OT protocol analysis

Headers and payload, network & OT protocols, capture and analysis, OT network threats, services protocols.

Part 3 Common Industries

Ch 9 — Electrical power: substations & IEC 61850

Substation components, automation system, IEC 61850 data modeling, network architecture, MMS / GOOSE / SMV / PTP protocols.

Ch 10 — Oil & gas

Upstream, midstream, downstream, pipeline monitoring, Modbus.

Ch 11 — Building management systems

BMS/BAS use cases, BACnet, BACnet/IP, BBMD.

Part 4 OT Cybersecurity

Ch 12 — Standards & regulations

IEC 62443, people-process-technology, RACI, security levels, foundational requirements, defense in depth, zones & conduits, capability maturity model.

Ch 13 — Risk assessment

Why risk-based, OT vulnerabilities, roles & responsibilities, threat vs. risk, how to actually run an assessment, risk calculation.

Ch 14 — Cybersecurity controls

Wrong assumptions, asset visibility, posture assessment, OT NIDS, NGFW/IPS, endpoint protection, IAM, OT NAC, secure remote access, zero trust.

Prerequisites

Who this is for

You'll get the most out of this if you have

  • Basic networking — OSI model, devices, IP addressing, subnetting.
  • TCP/IP communications fundamentals.
  • A general interest in industrial systems or critical infrastructure.

You don't need

  • Prior OT or ICS experience — Part 1 covers it from zero.
  • Cybersecurity certifications — though you'll be well placed for them after.
  • Access to a real plant. Walkthroughs and analysis exercises are self-contained.
