This dissertation was written as part of the MSc in Communications and Cybersecurity at the International Hellenic University. More specifically, this paper critically examines the implementation of Network and Information Systems Directive (NISD) by the identified operators of essential services (OESs) of the Critical Infrastructure (CI) sectors (public and private) and certain digital service providers (DSPs) for all Members in the European Union. To introduce the unfamiliar reader to cybersecurity conception, this thesis provides an analytic description of the general provisions of the NISD alongside the proposed security measures for all Member States. Following, it examines the way Greece has transposed the context of the directive into national laws and analyzes in detail its effectiveness, providing some conclusions about it. Subsequently, the thesis tries to reach some general conclusions about the context of the NISD, by understanding its significance since it must be regarded as a national priority among Member States. Finally, this paper studies the implementation of the NISD into Greek aviation industry making a recommendation for the air transport sector to set up an aviation cybersecurity strategy. It is also worth stating that the findings for this thesis were drawn from the literature, and empirical studies in Cybersecurity area.
