OT Security All-in-One, Volume 1: Foundations of OT, ICS, and SCADA Security
OT Security All-in-One, Volume 1: Foundations of OT, ICS, and SCADA Security is a 311-page professional reference work that builds the foundation every industrial cybersecurity practitioner needs: what operational technology is, how industrial environments actually work, and why OT security is not simply IT security applied to a factory.
Written for the world that moves, pumps, heats, cools, treats, manufactures, transports and generates, the book explains SCADA, ICS, PLCs, RTUs, DCS, HMIs, historians, sensors, actuators, safety instrumented systems and engineering workstations from first principles, then walks the Purdue Enterprise Reference Architecture level by level, from the physical process at Level 0 to the industrial DMZ at Level 3.5.
Thirty chapters cover the modern critical infrastructure threat landscape, the difference between data at risk and the plant stopping, industrial protocols including Modbus, DNP3, Profinet, EtherNet/IP and OPC UA, why legacy protocols were never built for security, protocol gateways, jump hosts and data diodes, secure industrial communications design, the OT security golden rules, safety before security and availability before convenience, and the human operator as a security control.
Each chapter follows the same practitioner rhythm: objectives, an opening control-room scenario, a plain-English explanation, an engineer-grade technical deep dive, a verified real-world incident, common failure patterns, a controls-and-evidence table, the board-level implication, a checklist, review questions and key takeaways. A final review chapter provides exam questions and a field checklist, supported by asset-foundation field templates, references and an index.
Written for CISOs, CIOs, COOs, OT security architects, control engineers, SOC leaders, GRC managers, auditors, board advisors, critical infrastructure operators, consultants, suppliers and system integrators, this volume is the operating manual for industrial cyber survival and the reference the rest of the OT Security All-in-One series depends on.
Key topics include: operational technology; ICS; SCADA; PLC security; Purdue model; industrial protocols; safety instrumented systems; industrial DMZ; critical infrastructure; OT risk; industrial cybersecurity; practitioner handbook.
