There has been an increase in cybercrime and a search for government or private company assets that have failed security and support critical infrastructure services. This paper addresses the issue of cyber security and its importance on the world stage. Cyberspace contains various information and critical infrastructure services that must be given special attention by the actors involved. In this context, cyber security policies are fundamental, as they establish the regulatory framework from which actions will be established and monitored, roles and responsibilities are defined. This study evaluates Brazil's Cyber Defence Policy (CDP) with the aim of contributing to the enrichment of discussions on this topic. To this end, the cyber security policies of other countries are analysed and their guidelines compared with the PCD. The relevance of the results is checked with an expert in the field. The work also presents aspects of the UCP that deserve attention.
