ABSTRACT
This chapter examines cyber power, identifies its area of influence in Brazil, and proposes ways to develop instruments of cyber power on behalf of the national defence. Since the assurance of defence is a product of the correct notion of space and time, it is important to establish the notion of time (when) and space (where) used in the chapter and how it relates to cyber power. The National Defence Policy (PND), approved by Decree No. 5,484, on 30 June 2005, was formulated to protect Brazil mainly against external enemies. It stipulates three strategic fields as priorities: nuclear, space, and cyberspace. Cyber power implies the expression of national power that seeks to regulate, control, and develop (in accordance with the moral principles of the society) the transmission of information between individuals and/or social groups as well as the effects of this relationship of power on attaining and maintaining the national objectives.
