Cyber warfare evokes different images to different people. This book deals with the technological aspects denoted by "cyber" and the information operations connected to social media\'s role in digital struggle. It discusses numerous mythologies about cyber warfare, including its presumptively instantaneous speed, that it makes distance and location irrelevant, and that victims of cyber attacks deserve blame for not defending against attacks. The volume outlines why beliefs about cyber weapons need modification and suggests more nuanced and contextualized conclusions about how cyber domain hostility impacts conflict in the modern world. It distinguishes between the nature of warfare and the character of wars, probes the widespread assumptions about cyber weapons themselves, explores the role of social media and the consequences of the digital realm being a battlespace in 21st-century conflicts, and considers security affairs and people\'s relationships with institutions and trends.
