HURLBURT FIELD, Fla –Students in the Undergraduate Network Warfare Training course at the 39th Information Operations Squadron inspect a model town used in an experiment to depict what could occur if a hacker invaded a water distribution plant’s control network.An off picture laptop acts as a human machine interface that serves to show water supply operators a graphic representation of the overall status of the water distribution. The simulated hacker was successful in this scenario and caused the water tank to overflow but still showed operators that everything was normal. UNWT represents the most comprehensive network warfare training available in the Air Force and graduated its fifth class Dec. 19. (U.S. Air Force photo/ Capt. Ashley Conner)
