Security Analysis of Meteorological Support Software for UAS Flight Planning

The unmanned aircraft system (UAS) operation depends on the weather significantly. This was the motivation to develop the decision support system that analyzes the range of factors including general and operative weather, type of aircraft, mission sensors, and area of flight to help remote pilots in their decision-making at the pre-flight stage and during the flight operation. Taking into account the cyber-physical nature of modern UAS it is important to evaluate the possible cyber risks that can be encountered during the operation of developed software. In this paper, the attack trees are built to understand how and for what reasons attacks on the software environment, database, or drone used to carry out the mission occur. The consequences of the cyber hazards are analyzed and some decisions on risk mitigations are made.
