Proceedings of the 6th edition of the ACM Workshop on Cloud Computing Security

It is our great pleasure to present to you the proceedings of the 6th edition of the ACM Cloud Computing Security Workshop (CCSW) held in conjunction with the 2014 ACM Computer and Communication Security (CCS) conference in Scottsdale, Arizona, USA, November 3-7, 2014. The paradigm of cloud computing has been revolutionizing todays' information communication technologies, impacting and redefining how data is stored, retrieved, processed and shared. Cloud services provide an elastic, scalable, large-scale environment typically marked by a high degree of resource virtualization and sharing among tenants. While the economic benefits of cloud computing are widely recognized, this new computing model creates security and privacy requirements different from traditional environments. With the wide adoption of cloud computing paradigm, security, privacy, and availability of the involved operations, components, and systems are becoming of increasing importance. The CCSW workshop focuses on the security challenges and research opportunities raised by the recent developments in cloud computing. The goal of the workshop is to explore the security and privacy challenges that are raised by cloud computing, and foster development of new ideas and solutions that can be transitioned into practice. The 2014 CSW workshop received a total of thirty-six high quality submissions, out of which twelve were selected by the program committee through a rigorous reviewing process. The workshop includes four invited sessions, three invited talks and one memorial session. We are delighted to have three keynote talks that bring new perspectives and practical problems from industry to the research community related to issues like security and privacy of data stored in the cloud, economic impact of security, and risk management in cloud settings. The three invited talks are: Joanne Martin, CISO and VP for IT Risk, IBM, \"Securing Cloud Environments for Enterprise Computing\" David McGrew, Fellow, Cisco, \"Privacy vs. Efficacy in Cloud-based Threat Detection\" Bryan D. Payne, Director of Security Research, Nebula, \"Reducing the Cost of Security in the Cloud\" The memorial session, organized by Elaine Shi, celebrates the life of Emil Stefanov and his research contributions to cloud computing security. The contributors to this session (Ari Juels, Srini Devadas, and Zygmunt Pizlo) discuss Emil's most impactful contributions to cloud security and beyond.
