Grid computing is a wide area parallel distributed computing environment where idle processor cycles and underutilized storages of geographically dispersed resources are utilized optimum way which act as a supercomputer. In this paper, the authors identify and explain the problematic key security issues and propose briefly some novel approaches for solving those existing security related problems lie in Grid computing environment. The conception of Grid states a potent wide area distributed parallel computing architecture with advanced services which is first presented by Ian Foster et al.. The key characteristic of this architecture is Virtual Organization (VO), where geographically distributed resources like CPU cycles, storage, software, etc. are shared and accessed across the multi administrative domains.
