While the prediction of cyberspace future landscape is quite difficult, Greece must seek to define the potential threats and understand the forces that are formulating the national, regional but also the global future of Cyberspace in order to modulate influence and adapt to these changes. As we look toward 2020 and beyond, it is crystal clear that there are significant challenges, issues and functions that might need to be taken under consideration. However, in order Greece to form an effective cyber defense strategy, a significant number of future challenges need, to be taken into account. Till now independent practical steps and incoherent cyber defense initiatives are under implementation. The majority of NATO nations but also a significant number of non-NATO nations developed their own national strategies in order to establish an efficient and effective response mechanism and roadmap for the future. The answer for Greece to all these future requirements, is a comprehensive mid-term strategic framework, through which the nation will guide its activities and will react to all changes and advances in technology, in order to actively meet both the threats and opportunities. Greece requires an “early warning-early response” cyber defense strategy in order to articulate the framework to 2020. The goal must be to keep technological efficiency and effectiveness in close cooperation and coordination with our allies and other critical stakeholders, in order the nation to be able to respond faster than vulnerabilities and threats will be exploited. Through this roadmap Greece will meet its vision for a safe, secure and resilient cyberspace and will establish a strong foundation for all efforts in the future full of challenges complex cyberspace environment.
