Secure Operations Technology
IT-SEC protects the information. SEC-OT protects physical, industrial operations from information, more specifically from attacks embedded in information. When the consequences of compromise are unacceptable - unscheduled downtime, impaired product quality and damaged equipment - software-based IT-SEC defences are not enough. Secure Operations Technology (SEC-OT) is a perspective, a methodology, and a set of best practices used at secure industrial sites. SEC-OT demands cyber-physical protections - because all software can be compromised. SEC-OT strictly controls the flow of information - because all information can encode attacks. SEC-OT uses a wide range of attack capabilities to determine the strength of security postures - because nothing is secure. This book documents the Secure Operations Technology approach, including physical offline and online protections against cyber attacks and a set of twenty standard cyber-attack patterns to use in risk assessments.
Cyber Security Operational Technology Environments
A Critical, Must-Read for Industrial Cybersecurity Professionals Mark Hayward's Cyber Security Operational Technology Environments is the definitive resource for anyone operating within or securing the world of industrial control systems. This book is vital because it addresses the single most critical gap in modern security: the chasm between traditional Information Technology (IT) defense and Operational Technology (OT) defense. Hayward provides exceptional clarity by defining the unique characteristics of OT. Unlike IT, which prioritizes data, OT is designed to control physical processes in manufacturing, energy, transportation, and utilities. This fundamental difference means that an OT security failure risks safety, physical damage, and mass downtime, not just data theft. What You Will Learn: The Foundational Difference: Why standard IT security policies fail when applied to systems designed for "maximum safety and efficiency" over confidentiality. Core OT Components: Gain a clear understanding of the security challenges posed by Programmable Logic Controllers (PLCs), Supervisory Control and Data Acquisition (SCADA) systems, and Distributed Control Systems (DCS). Strategic Imperative: Position yourself as the expert who can secure the hardware and software that monitors and controls real-world assets. This book is essential reading for CISOs, Security Architects, and OT Engineers who are responsible for maintaining the safety and efficiency of critical infrastructure. If you need to secure the systems that keep the lights on and the factories running, start here.
Industrial Control System (ICS) and Operational Technology (OT) Security
Operational Technology (OT) refers to hardware and software used to monitor, control, and manage industrial processes, infrastructure, and assets across sectors like manufacturing, energy, transportation, and utilities. It includes systems such as Industrial Control Systems (ICS), SCADA, PLCs, and DCS. ICS Security is the protection of industrial automation and control systems that manage critical operations like power generation, water treatment, and oil and gas production. Its goal is to safeguard confidentiality, integrity, and availability while mitigating risks from cyber threats, disruptions, and unauthorized access. With this book, our goal is to help readers understand how to secure complex industrial environments by providing a clear introduction to ICS and OT security. We will begin by explaining what ICS and OT are, how they differ from traditional IT, and why those differences matter. From there, the discussion will focus on the increasing importance of ICS/OT security—particularly in the context of IT and OT convergence, where systems and data are becoming more interconnected. You will also gain an understanding of the key components that make up Industrial Control Systems and how they work together to monitor and control industrial operations. These components—including SCADA, PLC, HMI, and DCS—are essential for ensuring operational efficiency, safety, and security in industries like manufacturing, energy, and critical infrastructure.
