Textbook of Cybersecurity: Methods for Detecting and Preventing Cyber Attacks BY Prof. Harshal Diwakarrao Wankhade,Dr. Ritu Aggarwal,Prof. Priyanka R Raval,Prof. Faizal Nujumudeen

PREFACE
In an increasingly interconnected digital world, cybersecurity has emerged as a critical domain for ensuring the confidentiality, integrity, and availability of data and systems. The rapid evolution of cyber threats, from ransomware and phishing to advanced persistent threats and zero-day exploits, necessitates a robust understanding of both the theoretical foundations and practical methodologies used to detect, prevent, and respond to attacks. With this pressing need in mind, we present the Textbook of Cybersecurity: Methods for Detecting and Preventing Cyber Attacks.
This textbook is the outcome of a collaborative effort by a diverse group of researchers, academics, and industry professionals who bring together their unique perspectives and experiences from various corners of the cybersecurity landscape. Each chapter has been carefully crafted by subject matter experts to provide readers with a comprehensive and up-to-date understanding of the field.
The structure of this book is designed to be both pedagogically sound and practically relevant. The initial chapters lay a solid theoretical foundation, while subsequent sections delve into applied tools, techniques, and real-world case studies. We have taken care to ensure that the content is accessible to students, professionals, and decision-makers alike—whether they are new to cybersecurity or seeking to deepen their expertise.
Our collective vision for this book is to empower the next generation of cybersecurity professionals, educators, and researchers with the knowledge and tools needed to navigate and secure an increasingly digital future. In addition, we aim to contribute to the global discourse on cybersecurity resilience and promote a more secure digital ecosystem.
We extend our sincere gratitude to the institutions and organizations that supported the development of this work, and to the reviewers and editors who provided invaluable feedback. Above all, we thank our readers for their interest in this field and hope that this textbook serves as a valuable resource in their academic, professional, and personal pursuits.
