While the Industrial Internet of Things (IIoT) and Wireless Sensor Networks (WSN) continue to redefine industrial infrastructure, the need for proactive, intelligent, and scalable cybersecurity solutions has never been more pressing. This book provides a hands-on, research-driven guide to building, deploying, and understanding machine learning models tailored for securing IIoT and WSN environments. Whether you're a student, researcher, or professional, this book takes you through the full data science lifecycle—from data collection and EDA to model development and deployment—with a special focus on real-world attack detection, anomaly analysis, and predictive defense strategies. What You’ll Learn: How to run cybersecurity-focused exploratory data analysis (EDA) Step-by-step model design, training, and evaluation for threat detection Building and deploying web-based AI cybersecurity solutions Practical use of Python Visualizing attacks and insights to drive decision-making Future trends include Edge AI, federated learning, and zero-trust security This book is thoughtful for Cybersecurity professionals working in industrial or smart environments, including smart cities, aerospace, manufacturing, etc. It is also a valuable resource for Data scientists and ML engineers applying AI to security, industrial engineers, and University students and educators in computer science, data science, and security. Build secure, data-driven defenses for the next generation of connected systems—start here.
