Hellenic Cyber Security Team 2023


Today, most countries lack sufficient IT security professionals to protect their IT infrastructure. The European Cyber Security Challenge (ECSC) is aimed at identifying new talent – by having national teams compete in a Cyber Security Challenge!

The European Cyber Security Challenge (ECSC), organized by ENISA, leverages these competitions in that it adds a pan-European layer to them: The top cyber talents from each country meet to network and collaborate and finally compete against each other to determine which country has the best cyber talents. To find out which country’s team is the best, contestants have to solve security related tasks from domains such as web security, mobile security, crypto puzzles, reverse engineering, and forensics and collect points for solving them.

The European Cyber Security Challenge (ECSC) is an annual cybersecurity event, aimed at identifying new talent across Europe by having national teams compete in a Cyber Security Challenge!

In this competition, young cybersecurity experts compete with each other by solving security related challenges, which require technical skills such as pen-testing, as well as soft skills in order to deliver a presentation. The activities of the ECSC are supervised by this Steering Committee, made out of representatives of the attending countries which are assigned by the European Union Agency for Cyber Security (ENISA).

For Greece, the role of Steering Committee member has been assigned from ENISA to the “Systems Security Laboratory of the Department of Digital Systems” of the University of Piraeus, represented by Prof. Christos Xenakis.

The Greek National ECSC Team operates under the auspices of the Hellenic Ministry of Digital Governance which is always in close cooperation with the Hellenic Steering Committee.
