Industrial Network Security is an accessible guide that explains how modern factories, utilities and chemical plants protect computer-based control systems. Written for readers without a cybersecurity background, this book describes what industrial networks are, why they matter to critical infrastructure and how commercial off-the-shelf (COTS) technology and increased connectivity create both benefits and new risks. It covers core concepts such as the AIC triad (availability, integrity and confidentiality), threat types (including viruses, worms and insider threats), common vulnerabilities (e.g., buffer overflows) and practical risk assessment methods.

This book presents a layered defense approach that combines design and planning, technical controls (such as firewalls, VPNs, intrusion detection and encryption) and human factors (policies, training, physical security and personnel security). Real case histories and new topics, such as red teaming, provide concrete examples of successes and failures. Overall, Industrial Network Security provides a concise and practical roadmap for managers, engineers and students seeking to understand how to secure industrial control systems.
