ABSTRACT
Grid computing is concerned with the creation of distributed virtual organizations across multiple control domains to enable the sharing of diverse remote resources. Due to its multi-institutional nature, securing the grid is one of the main challenges in grid computing. In this chapter we provide an overview of the grid security fundamentals, standards, requirements, models, architecture, and use patterns. We survey the major security challenges and requirements for grids, the main grid security models that address these requirements, current grid security architectures, emerging grid security standards and standard bodies, the convergence of grid and Web services, and the emerging enterprise grids.
