This is the second cyber security workshop to be held in Barcelona, Spain in Conjunction with IEEE FiCloud 2018 and Innovate-Data 2018. Cyber security continues to be a challenging area that requires a sustained commitment in terms of research, development and investment to ensure better solutions are developed. Although there have been excellent advances in this area, academic research into cyber security could benefit enormously by pooling resources together with other disciplines to provide novel ideas that can make the cyber space more secure without impacting upon performance and networking. This workshop is targeted at enabling the interaction of both academic and industry sectors and is looking at bridging the gaps in knowledge sharing and the development of workable solutions.
