Modern critical aviation information systems

Abstract

The problem of cyberterrorism is global and quite acute in today's information society. Leading world states are increasingly focused on critical information resources protection in different spheres. In civil aviation criticality level is amplified by communication and interaction between ground systems and aircrafts. Modern information and communication technology implementation in one hand increases civil aviation operation efficiency and in the other hand generates a set of new vulnerabilities and potential threats. Besides no one aviation security control document doesn’t include full list of critical aviation information systems, its functional features and criticality level. These make difficult the analysis of such systems, creation threat and intruder models, risk analysis and assessment and also not allow to formalize security methods against different cyberthreats. In the paper search and systematization of modern aviation information systems (information systems of aero navigation service, aircraft board information systems, information systems of air companies and airports) was carried out. Also critical aviation information systems analysis was fulfilled and basic features for its classification were defined. Given results should be used for further creation the extended classification and criticality level determining for critical aviation information systems.
