Fundamentals of Cyber Security and Digital Forensics

A practical, research-led reference

Fundamentals of Cyber Security and Digital Forensics has been developed to provide readers with a comprehensive understanding of the principles, technologies, practices, and emerging trends that shape the modern cyber security landscape. As digital systems become increasingly integrated into personal, organizational, and national infrastructures, the need to protect information, networks, applications, devices, and digital evidence has become more critical than ever. The book begins with the fundamental concepts and principles of cyber security, including the evolving threat landscape, before moving into computer networks, internet security, operating system protection, and endpoint security. It also provides a structured treatment of cryptography, secure communication, authentication, authorization, and access control mechanisms that form the foundation of secure digital environments. Subsequent chapters examine network security technologies such as firewalls, intrusion detection and prevention systems, along with web application and cloud security. The book also addresses malware analysis, cyber attacks, and defensive mechanisms, helping readers understand both the nature of contemporary threats and the methods used to mitigate them. A major focus is placed on digital forensics, including forensic principles, processes, evidence handling, and the investigation of computers, mobile devices, and networks. Cyber crime, cyber laws, digital ethics, incident response, risk management, and business continuity are also discussed to provide a balanced technical, legal, and organizational perspective. The final chapter explores emerging developments in artificial intelligence, blockchain, and zero trust architecture, highlighting their growing importance in future cyber defence strategies. Structured for both guided study and quick reference, the book brings together key concepts, current methods and practical context.
