The Role of AI in Cybersecurity is a comprehensive exploration of how Artificial Intelligence is transforming the landscape of digital security. As cyber threats grow more sophisticated and frequent, the limitations of traditional security approaches become increasingly evident. This book highlights how AI through technologies like machine learning, deep learning, and natural language processing is redefining the way organizations detect, prevent, and respond to cyberattacks. From real-time threat detection to behavioural analytics and malware identification, AI is enabling faster, smarter, and more adaptive cybersecurity systems. This book delves into both the technical mechanisms and real-world applications of AI in cybersecurity, offering readers an understanding of how these intelligent systems work, where they are most effective, and what challenges they still face. In addition to technical implementations, the book also addresses critical ethical and regulatory considerations. Topics such as AI bias, data privacy, automated decision-making, and the need for responsible AI governance in cybersecurity are thoughtfully explored. Whether you’re a cybersecurity professional, researcher, student, or simply curious about the intersection of AI and digital security, this book offers valuable insights into the current state and future potential of AI-driven defense systems. Through a mix of foundational knowledge, emerging trends, and practical examples, it provides a well-rounded perspective on one of the most important developments in modern cybersecurity.
