In a presentation at the Black Hat and Defcon security conference in July, for instance, French security researcher Andre Costin presented vulnerabilities in the next-generation air traffic control system known as ADS-B that he said would allow a hacker with a software-defined radio to track and even spoof planes in the sky, potentially creating dangerous distractions for pilots.
Under the new system, software will analyze the entire Norfolk network every hour and, to keep traffic flowing efficiently, suggest changes in speed, routing and train meeting places.
