FIGURE 1. CYBER ECOSYSTEM

The IT component that describes cyberspace is made up of two main parts the Internet and isolated systems
(networks, systems and storing devices not connected to the Internet).
012.
In the military world, both the Internet and isolated systems are crucial the Internet provides global connectivity and massive access to information, and the isolated systems provide an effective environment to manage classified information and to carryout activities that require a high level of confidentiality and isolation.
013.
These two characteristics, global connectivity and isolation, are not exclusive of each part of cyberspace (the Internet and isolated systems, since confidential and isolated environments can be created on the Internet and isolated networks can be implemented with high connectivity. But they are not the natural environments.
014.
Both parts, the Internet and isolated systems, are paramount in a national cyber defense framework, considering that global connectivity is essential in order to have extensive access to information and for national and international cooperation and isolation and confidentiality are fundamental in the activities related to operations and research and development.
Cyberspace layers
015.
From a practical and operational point of view, it is helpful to assemble the components that interact in cyberspace indifferent layers (human, cyber-human,
cognitive, logical, IT infrastructure and
geographic) to facilitate the assignment, organization and distribution of activities, functions, services and responsibilities.
016.
Different activities are performed in each of the layers, relating to different means, processes and professional profiles.
017.
The representation of cyberspace in layers follows a logical process whereby humans generate knowledge that is processed on information systems implemented in IT networks located in specific places of the geography.
