When most people think of cyberwarfare, they think of CNA. They believe such attacks will bring down electrical grids. They imagine cars coming to a halt in their tracks. They imagine planes crashing. All of these are theoretical possibilities.
CNA stands for computer-based asset compromise and system manipulation. Systems can be shut down, data can be altered, resources can be used for botnets, and any other action that jeopardises a system's integrity or availability can be taken. The organization's computer system is either utilised against it or its resources and data are made unavailable.
