The emergence of Artificial Intelligence (AI) has drastically altered the conditions of warfare. AI now plays an integral role in every facet of a nation-state's military/surveillance structure, from cybersecurity to espionage to covert operations. AI technologies are reshaping the science of cyber warfare. A single slip could mean dire consequences with the new world order where AI technologies have become mainstream not just for nation states but organisations as well. For organisation and state-sponsored alike, the associated risk grows ever higher against stakes that have outpaced sophistication which can be claimed to be unprecedented. This book outlines the new standards where deep learning, automated reasoning, and advanced algorithms have created new frontiers on offence and defence in digital warfare. A single error in enterprise security could lead to the downfall of a business. Exceeding malware threats and recovering inside jobs have become trivially easy now AI powered programmes have taken the wheel. AI systems can execute actions at lightning speeds allowing business alongside governments to carry out covert operations without breaking a sweat. A powerful pioneer such as AI comes with risks that do not only end at the sidelines. Offensively, AI can now be applied to autonomously run social engineering schemes through swiftly mobilisable global bots that rapidly span across borders. These nodes come armed with advanced features like adaptive maneuvers and evasion protocols, allowing them to adapt the information they feed to infiltrator malware all while dodging identifiers and making undetectable changes in real time. In a world superseded by advanced technologies, one does not simply remain undetected.By using practical examples and future-focused studies, the book explores how AI can act as both a protective shield and a sword. Most importantly, the book does not act as a mere technical guide. It analyses the social, legal, and political consequences of AI cyber-power strategies. What constitutes permissible boundaries of electronic warfare? How do global treaties cope with autonomous strategy algorithms for attacking? In an AI-enabled warfare, where does human accountability start and stop? It is intended for practitioners in security, IT executives, scholars, and other concerned citizens who wish to engage with the future of digital technology. This book untangles the complicated theories and concepts of modern cyber defence and offence, equipping readers to deal with these challenges in the future. If you are looking for protective strategies for your organisation, or want to understand emerging cyber threats, Cyber Defence and Offensive AI Strategies offers an authoritative yet balanced take on the global intelligence competition that is urgently reshaping the world's digital infrastructure.This text will be highly useful for cybersecurity practitioners, IT managers, penetration testers, and threat intelligence analysts looking to familiarise themselves with the new dimensions of AI technology in both defence and offence of cyber domains. Security architects and CISOs will find relevant actionable strategies on use of AI in their defensive strategies, while educators, students, and researchers in computer science and security studies will find a thorough contemporary reference. Besides, policymakers, lawyers, and ethical commentators concerned with the social consequences of autonomous cyber operations would be interested in the book's discussions on regulation and the limits of warfare in cyberspace. It doesn't matter whether you are a seasoned authority, an emerging professional, or simply someone who cares about the evolution of digital security. This book is a must-read for you.
