Protection of Air Transport Against Acts of Unlawful Interference: What's Next?

75-88

Air transport consists in moving people or goods by air. Aircrafts, known as the main means of air transport, can be divided into two categories: airplanes and helicopters. Such transport is the most modern and the most dynamically developing branch of transport. It is also considered to be the safest mode of transport, even though, for various reasons, aviation accidents still occur. Security in aviation has various connotations. According to the International Civil Aviation Organization (ICAO), it is a state in which the possibility of damage to persons or property is minimized and is maintained as part of a continuous process of hazard identification and safety risk management at an acceptable level or below this acceptable level. Aviation security includes flight safety and aviation security against acts of unlawful interference. There is a significant difference between the meaning of "safety" and "security". The first of these concepts means preventing unintentional damage, while the second refers to the procedures undertaken in order to prevent deliberate damage resulting from an intentional act. As it appears from the abovementioned information, the immovable part of aviation safety is aircraft protection, including the protection of civilian airports.The aim of the article is to draw attention to the problems of air transport security, including the security of airports, related to the evolution of threats and the functioning of the airport security system. The problem that the authors address is expressed in a question: in what directions should the current solutions in the field of air transport security be improved in order to effectively prevent acts of unlawful interference in the future? Theoretical research methods, such as the analysis and synthesis of information contained in literature and source materials, inference, comparison, were used to develop the article.

The article deals with the problems in constructing a protection system of executable code. The techniques of breaking the integrity of executable code and ways to eliminate them are described. The adoption of virtual machine technology in the context of executable code protection from analysis is considered. The substantiation of the application of virtual machines as the best way to oppose the analysis of executable code is made. The protection of executable code by transferring the protected code in a virtual execution environment is considered. An efficient implementation of the method is proposed. Also, general characteristics of information systems software life cycle are specified in this paper, considered software protection applications reliability questions and use of fail-safe ensuring programming. In addition there presented some known models used for software debugging and operating.

Artykuł dotyczy problemów w opracowywaniu systemów ochrony kodu wykonywalnego. Zostały opisane techniki przerwania integralności kodu wykonywalnego. Uwzględniono zastosowanie technologii maszyn wirtualnych w kontekście ochrony analizy kodu wykonywalnego. Przedstawiono dowód na zastosowanie maszyn wirtualnych, jako najlepszego sposobu przeciwdziałania analizy kodu wykonywalnego. Ponadto przedstawiono ogólną charakterystyka systemów informatycznych, cyklu życia oprogramowania, ochrony oprogramowania, kwestie niezawodności aplikacji oraz zapewnienia bezawaryjności działania oprogramowania
