NATO networks are susceptible to a variety of threats and actors. The military needs to operate in this contested, and at times, chaotic domain.
Military organizations are heavily reliant on CIS for their activities, whether it is for Command and Control purposes, or for the use of the latest weapon systems.
The cyberspace has added a new dimension to military activities and warfare. The actions that take place in cyberspace is becoming a game changer as cyber security not only permeates all aspects of military activities but also affects all aspects of the life of a modern society.
