CIA runs cyber war game
In May 2005, several US news outlets reported on a classified war game being conducted by the US Central Intelligence Agency (CIA) to rehearse defending against a massive electronic cyber attack. The exercise, entitled 'Silent Horizon', follows 'Livewire', a similar war game run earlier by the Department of Homeland Security. 'Silent Horizon', according to reports, sought to follow on from the lessons learned during 'Livewire' and other war games, and was in part intended to test responses to large-scale, multiple attacks.

This decade truly sucks. I believe I've mentioned this before.
