Civil aviation is an important asset of today’s mobile society and belongs to the critical infrastructures. Thus, the protection of civil aviation is of high importance to society.
In aviation, economic pressure requests cost reductions and improved efficiency in handling aircraft. As a consequence, the infrastructure and technical systems become more and more interconnected to save costs through re-use of resources and exploitation of synergies. Besides these desired effects, the interconnection of formerly separate technical systems generates new risks. These risks are especially caused by threats from cyberspace. Main goal of the project ARIEL is to perform a holistic risk analysis and evaluation of critical infrastructures in aviation, since these might become the target of sophisticated cyberattacks to create new threats to public safety and security.
Main goal of DLR’s work in the project ARIEL is to determine and analyze potential threats at the physical layer of current and future technologies for communications, navigation, and surveillance (CNS) in aviation. To achieve this goal, the work is subdivided into three steps. First step is to capture and describe the current as well as the near-future CNS infrastructure (Work-package “Scenarios”). Based on the obtained description, in a second step, vulnerabilities of the CNS infrastructure are identified which might be used by attackers to intrude into the infrastructure. In the third step, potential attacks to the identified vulnerabilities together with their impact onto safety and security in aviation are investigated and assessed. The final results will be used to compile a set of recommendations to stakeholders, where improved security measures need to be put into place.
