Evaluation of Cyber Security in Digital Avionic Systems

In the course of the project “Aviation Cyber Security Study” (ACySS) [1] the IT security of avionic components and systems was investigated. The aim was to uncover security weaknesses in critical and non-critical network domains in order to describe recommendations for avoidance. For this purpose, a testbed consisting of avionic hardware was set up. Based on this testbed, attack scenarios were developed and implemented. The first part of the study deals with a risk analysis on several levels, whereby attack scenarios were recorded from the perspective of an ordinary passenger. The second part deals with the technical investigations of network components and the Inflight Entertainment System.
