Özet:

Critical infrastructure is defined as "facilities or infrastructures that can cause loss of life and property when confidentiality, integrity or accessibility is weakened or that may damage national security and public order." On a sectoral basis, the transport sector is handled within the framework of critical infrastructures in many countries. The fact that critical infrastructures meet the increasing communication needs through network and internet connections makes these institutions more vulnerable to cyber attacks. The fact that the current cyber security measures for airports are focused only on flight control systems, increases the importance of the issue. Airports, where passenger, baggage and cargo transportation are carried out simultaneously, need more general cyber security policies to cover all these activities. The aim of this study is to emphasize the importance of protecting the airports, which should be considered as a critical infrastructure in the scope of cyber security applications, to increase the awareness of the possible weaknesses and to contribute to the cyber security of airports. In this context; in the first part of the study, studies, applications and legal arrangements on cyber security and critical infrastructure cyber security were examined. Previous cyber attacks against critical infrastructures were examined and evaluations were made. In the second part; the legal regulations and public policies on cyber security and protection of critical infrastructure implemented in Turkey are given. In the third and last part; evaluations and suggestions on policies aimed at improving the protection of critical infrastructure and cyber security in Turkey are given.
