What is Cyber Defense?

Cybernetic Defense is a set of techniques used to defend the diversity of servers, electronic systems, networks, computers and other devices from online attacks .

Basically, the concept concerns actions carried out in cyberspace. That is, we are talking about the entire domain of the computer network, but in the context of national planning at a strategic level, coordinated and integrated by the Ministry of Defense.

Its objective is to protect information assets of interest to the National Defense , in addition to obtaining data for the production of Intelligence knowledge and, furthermore, seeking superiority over the information systems of adversary countries.
