Following the success of NIS'08 and NIS'09, the 3rd edition of the Summer School on Network and Information Security (NIS'10) will cover topics that address legal, technical, and policy issues in this emerging world. ENISA and FORTH have taken the initiative to create this Summer School following the recognition of the importance of NIS and the need for raising awareness. The Summer School aims to provide a forum for experts in Information Security, policy makers from EU Member States and EU Institutions, decision makers from the industry, as well as members of the research and academic community, for interacting on cuttingedge and interesting topics in NIS.
