Information Security in future ATM Systems

The detection, identification and evaluation of vulnerable areas generated by the use of advanced technologies associated to the Communication, Navigation and Surveillance (CNS) infrastructure is the cornerstone of the threat analysis required to improve the security of both current and future Air Traffic Management (ATM) systems. The security analysis includes the identification of the assets, understood as things of value or things to protect from potential threats. In the future context, an infrastructure for information sharing will be deployed to enable the robust data exchange among ATM stakeholders. Information will become a major asset to be protected. The present paper aims at presenting the future ATM environment analyzing the impact of intended attacks on flight and surveillance information and how the effects are propagated throughout the whole system. For illustration purposes different potential scenarios are described in order to facilitate the identification of applicable countermeasures which can ensure confidentiality, integrity and accessibility of the data.
