CYBERACTIONING project is originated by a consortium originally formed within the European University Alliance ARQUS, with the addition of five SMEs and a Research Centre, all of them covering four different European countries and with a high level of expertise in the field of cybersecurity. It aims to train professionals in this field through the following initiatives: (a) a joint European Master in cybersecurity with a mobility path along the four universities; (b) a MOOC in cybersecurity aiming at training a minimum of 800 students from non-ICT sectors in each edition; (c) a scholarship programme to attract highly qualified students; (d) a programme of agreements and incentives to attract faculty, companies and research centres and generate synergies; and (e) the acquisition of key technological infrastructure for support of the programmes.
