This book is not about promoting cyber warfare; rather, it aims to help peace lovers, policy makers and defenders of the freedom of India understand the cyber warfare that is already being waged, so as to defend our cyber and cyber dependent assets, critical to national security, and deter future cyber warfare. The book explores in depth and detail, the place and role of cyber warfare in the emerging national security calculus, with special emphasis on military networks and aviation cyber security besides addressing the concerns related to the governance of the internet, and how India can tackle the complex cyber warfare challenge strategically. For those who share the increasing global cyber anxiety, who seek to grasp cyber security issues at global, national and military levels, and who want India to remain secure from cyber threats, this book is an essential read.
