ABSTRACT
Grid systems were initially developed for supporting scientific computations. Today, companies, users and researchers are looking at ways to use the Grid approach to commercial uses and for applications in many different areas. Security in grid systems however has not been much addressed and yet is an important prerequisite to really make grid systems usable in a variety of commercial applications.The goal of this panel is to explore relevant security issues, with special emphasis on access control, for grid-based computing systems. The panel will discuss security requirements that are specific to grid-based systems and set these systems apart from conventional distributed systems, and outline directions for future research. Questions addressed by the panel include the following ones:
What needs to be protected in a grid system: hosts, resources, data, computations?
Access control languages and policies: do we need ad-hoc languages for specifying access control policies for grid hosts? If so, which would be the most relevant and features of these languages?
User requirements: different grid hosts may provide different levels of security. How can a user specify his/her security requirements when running computations? Which assurance has the user that his/her own requirements have been met?
Scalability and evolution: grid computing systems may encompass a very large number of nodes (hundreds or even thousands). Moreover, they can be quite dynamic with hosts and clients dynamically joining and leaving. How can we design scalable access systems able to cope with the required dynamicity?

Grid-computing portals and security issues
Scalable web services and architectureComputational grids provide computing power by sharing resources across administrative domains. This sharing, coupled with the need to execute untrusted code from arbitrary users, introduces security hazards. Grid environments are built on top of platforms ...
Grid Computing Security: A Taxonomy
Grid computing helps us overcome heterogeneity in terms of computing elements, operating systems, policy decisions, and environments. However, security issues impede us from adopting the grid as a widespread IT virtualization solution, so we must ...

ACAI '11: Proceedings of the International Conference on Advances in Computing and Artificial IntelligenceGrid computing has made substantial advances during the last decade. A major concern in Grid environments is dealing with the high degree of heterogeneity of resources that can range from laptops and PCs to supercomputers. The unified virtual view of ...
