Over the past decade we have seen an impressive increase in cyberattacks ranging from ransomware to IoT DDoS attacks. Such cyberattacks are usually driven by cybercriminals who are financially motivated: they do the attack to gain money: they charge credit cards, they empty bank accounts, they ask for ransom, and in general, they find quite a number of ingenuous ways to monetize these attacks. Having realized the severity of the problem, the European Commission has started building a sequence of defenses including the European Cyber Shield. Although most of Europe is building defenses against cyberattacks, Greece is unfortunately lagging behind. For example, according to the ENISA map of CSIRTs, Greece has a very small number of operating CSIRTs (per capita) among countries of similar size in Europe. At the same time, Greece is hammered with cyberattacks - much more intensely compared to countries of similar size. Indeed, recent results (https://www.ekathimerini.com/economy/1177683/greece-ranked-5th-in-phishi... shows/) suggest that Greece is ranked among the top 5 countries in the world with the most phishing attacks. To be able to address these cyberattacks, Greece needs a new generation of vibrant Security Operations Centers that can monitor a large percentage of the Internet to find signals of attacks. C-SOC proposes the development of such a Security Operation Center in the island of Crete. Supported by FORTH, one of the leading Research Centers in the area of Cybersecurity, C-SOC
