The book serves two very important purposes. Firstly, the concept of vulnerabilities due to cyberattacks in all walks of lives are explained along with how to detect and reduce the risk through digital forensics. Secondly, the book describes how such threats at a larger scale can threaten national security. This book discusses for the first time various dimensions of national security, the risks involved due to cyber threats, and ultimately the detection and prevention of cyber threats through cyber forensics and cybersecurity architectures. This book empowers readers with a deep comprehension of the various cyber threats targeting nations, businesses, and individuals, allowing them to recognize and respond to these threats effectively. It provides a comprehensive guide to digital investigation techniques, including evidence collection, analysis, and presentation in a legal context, addressing a vital need for cybersecurity professionals and law enforcement. The book navigates the complex legal and policy considerations surrounding cybercrime and national security, ensuring readers are well-versed in compliance and ethical aspects. The primary purpose of Cybersecurity, Forensics and National Security is to fill a critical gap in the realm of literature on cybersecurity, digital forensics, and their nexus with national security. The need for this resource arises from the escalating threats posed by cyberattacks, espionage, and other digital crimes, which demand a comprehensive understanding of how to investigate, respond to, and prevent such incidents.
