The use of UAVs in various domains is continuously increasing. The advantages of UAVs provide to ability to facilitate functionalities or perform activities such as search and rescue that otherwise could not be possible, all while maintain low cost. Further-more, UAVs are important for the military domain since they are considered as efficient weapons. Therefore, many countries and retail companies are investing towards the massive production of UAVs for market as well as government purposes. Nevertheless, most UAVs, including military, lack even basic cybersecurity mechanisms, thus posing a cybersecurity threat that significantly affect cybersecurity aspect or result in physical damages and even loss of human life. Many cybersecurity solutions are proposed in-cluding both reactive and proactive measures, with the latter being more preferable. Threat modeling emerges as an effective proactive measure with minimal cost and complexity.
The current thesis conducts an extensive and comprehensive research concerning the domain of UAVs and the Internet of UAVs infrastructure. Initially, the thesis provides the history of UAVs and the different taxonomies that are available in the literature. A comprehensive description of the IoD environment and the various relevant cybersecu-rity issues is included in the next sections. Subsequently, the thesis provides an exten-sive study and evaluation of the variety of threat modeling approaches in the literature, while categorising relevant papers as either describing solutions which integrates threat modeling or proposing a novel threat model approach. Finally, the thesis describes the development and results of two technical experiments concerning the study of UAV communication vulnerabilities as well as an anti-drone system that leverages thermal detection.
