The fast development and adoption of Internet-based computer systems have left their users in misconception concerning the various risks associated with online networks. It is only recently that cyber risk has started to be seen as the serious threat that it is, which in turn reflects on the growing amount of research on the topic. In the aim of improving cybersecurity, the role of research is essential, as it raises awareness and contributes to a good breeding ground for cyber safety development.
