The term “cyber” has been used widely in recent times and in particular in the context of security. Given the wide usage in formal and informal contexts, it is possible that its origin and true meaning will not be fully appreciated and understood. The Cooperative Cyber Defense Center of Excellence (CCDCE) has made available a range of various definitions. The term cyber has become very prevalent and appeared in many national and international statements and in some cases having contradictory interpretations. This chapter aims to revisit the term cyber by walking through its use in various contexts. It starts from the context of the word’s origin; what is really entailed in the cyber world; and definitions portraying the understanding of the term from academics, national, and international organizations. Finally, the chapter combines the different interpretations into a single abridged definition from the various accumulated perspectives.
