CIA war game simulates cyber-attack

THE CIA is conducting a secretive war game, dubbed ‘Silent Horizon’, this week to practice defending against an electronic assault on the same scale as the September 11 terrorism attacks.

The three-day exercise, which ended yesterday, tested the ability of government and industry to respond to internet disruptions over many months.

Participants spoke on condition of anonymity because they had been asked not to disclose details of the exercise in Charlottesville, Virginia.
