    In recent years, there has been a growing demand for cybersecurity experts, and, according to predictions, this demand will continue to increase. Cyber Ranges can fill this gap by combining hands-on experience with educational courses, and conducting cybersecurity competitions. In this paper, we conduct a systematic survey of ten Cyber Ranges that were developed in the last decade, with a structured interview. The purpose of the interview is to find details about essential components, and especially the tools used to design, create, implement and operate a Cyber Range platform, and to present the findings

    This article presents the cybersecurity progress in Greece since the creation of the Greek National Cyber Security Authority as nation-wide cybersecurity coordination and policy-making unit. During this period, Greece issued a Ministerial Decree that established the National Cyber Security Authority, issued the National Cybersecurity Strategy, transposed the NIS Directive to National Law, and issued a Ministerial Decree that helped establish a cybersecurity framework for the public sector and the critical infrastructures that reside in Greece. This structured effort led to the achievement of gaining the 1st position in the prestigious NCSI index for Greece, amongst 160 countries.

    Smart cars have started taking over the world and, sooner rather than later, they might become the new normal in the automotive industry. Over-the-air software updates have been developed and established in the telecommunications industry and proven their worth. Their adaptation to the automotive industry has its challenges seeing as human lives are at stake there. A lot of work has been done to shorten the gap, so much so that this technology has already been applied to car models in the market sometimes successfully and others not. Until the gap is non-existent, there is still a lot to learn and improve on. This paper has described the advantages, threats and vulnerabilities tied to smart cars and over-the-air updates; it has gathered a list of existing solutions to them and a short examination of the situation in today’s relevant research and industry.
