"FAA has made progress in implementing information security for its air traffic control systems by establishing an agencywide information security program and addressing many of its previously identified security weaknesses; however, it still has significant weaknesses that threaten the integrity, confidentiality and availability of its systems -— including weaknesses in controls that are designed to prevent, limit and detect access to those systems." Source: A new report from the Government Accountability Office -- the investigative branch of Congress -- which says the FAA simply hasn't done enough to protect its systems from hackers. The FAA says the report doesn't reflect the true state of security in the nation's control towers and ATC centers.
