A Computational Grid is a collection of heterogeneous computers and resources spread across multiple administrative domains with the intent of providing users uniform access to these resources. There are many ways to access the resources of a Computational Grid, each with unique security requirements and implications for both the resource user and the resource provider. A comprehensive set of Grid usage scenarios are presented and analyzed with regard to security requirements such as authentic cation , authorization, integrity, and confidentiality. The main value of these scenarios and the associated security discussions are to provide a library of situations against which an application designer can match, thereby facilitating security-aware application use and development from the initial stages of the application design and invocation. A broader goal of these scenarios are to increase the awareness of security issues in Grid Computing. In the networked access to computation with a single-sign-on system as the portal to the possibilities of world wide computing grids security plays an important role. Keywords: Grid Computing, Security, Intrusion detection system etc I. INTRODUCTION Security is a latest topic today for the smart grid, and progresses are being done in this field every day. Most communications uses standard cryptographic algorithms AES-128 to protect the data on the network. Grid computing is a technique which provides high-performance computing; in this resources are shared in order to improve the performance of the system at a lower price. According to literature, “Grid computing is a system where multiple applications can integrate and use their resource efficiently”. According to Foster and Kesselman , “A grid is a system that has three important categories: coordination of resources not under centralized control, use standard general purpose interface, and it delivers nontrivial quality of service”. Kon et al define grid computing as, “coordination of resource sharing and dynamic problem solving in multi-institution virtual organizations” One goal of software designed as infrastructure supporting Computational Grids is to provide easy and secure access to the Grid’s diverse resources. First we survey security problems which exist in grid computing and then we analyze security requirements. At the end we introduce a framework which Erin Cody has posed as a solution for security problems of grid computing. The classification system group grid security solutions according to system solutions, behavioral solutions, hybrid solutions as well as technologies related to grid that could be useful in providing grid security. II. SECURITY REQUIREMENTS Grid systems and applications require standard security functions which are authentication, access control, integrity, privacy, and no repudiation. Authentication and access control issues are. It provides authentication to verify the users, process which have user’s computation and resources used by the processes to authenticate (2) allow local access control mechanisms to be used without change. To develop security architecture we have to satisfy the following constraints which are taken from the characteristics of grid environment and application. Single sign-on: A user should authenticate once and they should be able to acquire resources, use them, and release them and to communicate internally without any further authentication. Protection of credentials: User passwords, private keys, etc. should be protected.
