explores the strategic and tactical approaches for offense and defense in the digital age. Drawing on historical conflicts from Sun Tzu to Carl von Clausewitz, the author illustrates that, despite changed conditions such as time, location, means, and resources – but not the laws of physics – it is possible to learn from past actions and reactions. The author aims to demonstrate in this book that, in reality, we have only transferred old methods into our current era but have forgotten to translate their reasons, effects, and the resulting lessons. For, as it has been for thousands of years, the reasons for human-created conflicts remain the same: wealth, fame, power, honor, or desire. Can we learn something from history for present and future (cyber) wars?
