Researchers at the University of Illinois at Urbana-Champaign and the U.S. National Science Foundation recently organized a workshop on security for cloud computing. The goal of the workshop was to identify the research challenges for securing cloud computing services and systems and to rally a broader computer science and engineering research community behind the challenges that need to be solved. The researchers developed challenges in adversary models for cloud computing, delegation and authorization in cloud computing, end-to-end security in cloud computing, and new problems in security for cloud computing. The workshop brought forward many new challenges in well-known areas of security as well as new security problems that are emerging in the cloud computing domain. The researchers noted that the effort is needed because clouds are complex systems with hundreds of service dependencies, competing solutions, and multi-tenancy demands, and are being held back by a lack standards and pressures for interoperability, bandwidth, and other resources.
