The First International Conference on Frontiers in Cyber Security (FCS 2018) will be held in Chengdu, P.R. China from November 5th to November 7th, 2018, organized by the Center for Cyber Security, University of Electronic Science and Technology of China (UESTC). The cyber security is paid more and more attention by industry and academia. New cyber security technologies are emerging. Many universities and institutions have set up the research center or school for cyber security. Both government and enterprises are strongly supporting teaching and research in the cyber security. However, how to carry out research and education on cyber security is inexperienced. How to run the center for cyber security is also worth exploring since new center usually involves many departments. The FCS conference provides a good platform for researchers and practitioners to exchange the latest research results in cyber security and management experience in operating such a center. The conference proceedings are planned to be published by Springer Communications in Computer and Information Science (CCIS) which is indexed by EI.
