Cybersecurity in the Age of Artificial Intelligence: Securing the Future of Intelligent Systems

Artificial intelligence has stopped knocking politely on cybersecurity’s door—it has barged in and started rewriting the rules. From phishing emails that mirror a colleague’s tone to adaptive malware that evolves in real time, AI has turned threats faster, smarter, and harder to predict. Traditional defenses—static rules, perimeter controls, blacklists—are faltering against systems that learn, infer, and sometimes hallucinate with unsettling confidence.

This book is a clear-eyed guide for leaders, engineers, and policymakers navigating this volatile terrain. You’ll learn how attackers already use AI to automate reconnaissance and craft malicious code, why defending AI demands new thinking, and what it takes to design trustworthy, explainable systems. Packed with real-world examples and practical strategies, it will help you make better decisions—and avoid the costly mistake of treating AI as just another tool in your security stack.
