# Legal, Economic and Cyber Security Framework Considerations for Drone Usage
## 2 Literature Review Analysis
### Economic Perspective  
The third crucial perspective of drone use is the economic one. We outline below a few representative studies from this perspective. These generally analyze only the economic advantages, without analysis of the impact of cyber security and the clear identification of liability regarding the use of drones. Additionally, in 2017, material on the new economic era was presented at the United Nations Conference on Trade and Development (UNCTAD) [14]. It shows all the ways in which the economy has changed, becoming digital, but attracting a multitude of benefits with this transition. It also presents business models, along with the strengths and challenges of their implementation. This point is reflected by other studies published in recent years, such as those mentioned below. In 2018, [PERSON] et al. [15] discussed the development of the digital economy, with an emphasis on the use of drones in the field of construction. Similarly, Deloitte, in their study [16], addressed similar aspects and went further in terms of the role of drones in the infrastructure sector. In 2020, [PERSON] addressed similar issues concerning the use of drones in the medical field [17]. These studies emphasized only the usefulness of drones from the viewpoint of the economic sector's need for efficiency in operations. However, they do not address other angles that should be held in mind when deciding on the use of drones in a particular sector, including cyber-attack prevention, the role of each stakeholder in the drone ecosystem concerning the proper functionality and cyber security of the drone. Furthermore, each of the below studies presents certain specific aspects to take into account when designing the information security preventive measures (based on the used technology) and, given each particular IT solution, liability in the case of cyber-incidents can be determined differently. In 2019, [PERSON] et al. [18] described the idea of developing drones that transmit a network for radio coverage in crowded urban areas, touching upon the quality of service of drone usage and, briefly, ensuring the availability of drones. This entails enhanced and complex algorithms, including neural networks detailed by [PERSON] et al. in 2019 [19], while taking into account specific Internet of Things aspects, as detailed by [PERSON] et al. in 2019 [20]. Whereas these availability aspects are important, confidentiality and integrity principles should also be analyzed. A step in this direction has been made in the literature concerning evolution of IT solutions, including in 2020, when [PERSON] et al. described and developed an analytical framework for secure IT evolution [21]. Prevention and control methods are analyzed, while highlighting the role of IT infrastructures in the context of technological development. Nevertheless, for the drone ecosystem, the specifics of its creation and maintenance have to be taken into account when designing cyber-attack liability and prevention mechanisms. Thus, the use of drones can vary significantly, depending on location in the world and on the economic field. The above studies concentrate on the usefulness and efficiency of drones for activities that are currently being performed by humans or other automation mechanisms. Nevertheless, they do not investigate the reasoning for the increased usage of drones in certain geographic areas or economical areas, especially in terms of a cost-benefit analysis taking into account the cost of drone purchase and maintenance, cyber security during the lifetime of the drone and the clear identification of drone liability in case of incidents. As a conclusion to the literature review performed from multiple angles (legal, technological and economy), the usefulness of drones is an indisputable phenomenon, based on the number of studies that attest to the great results they have in their actions. The legal framework is an aspect that will be constantly evolving, because the conditions of use are changing at approximately the same rate as the device upgrades.
