Once the USAF Cyber Command was effectively put on ice recently, coverage of the US military’s approach to network warfare and defence also went away. The existing infrastructure and systems that had been in place prior to the attempted set up of Cyber Command still continue to operate and the head of US Strategic Command, General Kevin Chilton, recently spoke about a range of the issues being faced in operating the US military’s lesser-classified networks.General Chilton is continuing to support the concept that “cyberspace” represents a fifth realm of warfare, complementing air, land, sea, and space as the realms that battle will be conducted in into the future. This idea is one that still has its critics even though it has been in use since at least 1996.
