The most important recent development in Grid systems is the adoption of the Web Services model as its basic architecture. The result is called the Open Grid Services Architecture (OGSA). This paper describes a component framework for distributed Grid applications that is consistent with that model. The framework, called XCAT, is based on the U.S. Department of Energy Common Component Architecture (CCA) but with an implementation based on the standard Web Services stack. Using this framework, an application programmer can compose an application from a set of distributed components. The result is a set of WebServices that collectively represent the executing application instance. This paper describes the basic architecture of XCAT and the design issues to be considered for a component to serve as both a CCA and Open Grid Service Infrastructure (OGSI) service.

This paper proposes a system to provide security for the grid infrastructure where authorization and authentication will be made scalable by setting up an authorization framework at the resource provider's end. Our proposed architecture intends to relieve the grid middleware from taking the responsibility of the authorization mechanism, as well as improves the resource provider's trust in the event of a request from the data portal, since the authorization policy will be pulled from its own organizational server. We will demonstrate that this architecture is secure, scalable, and robust, by improving the existing authorization mechanism in Grid infrastructures.

“…The ability of a service to delegate this responsibility to an agent making and monitoring these types of contracts greatly reduces the complexity of a service. The design seeks to increase flexibility, robustness, maintainability and portability by abstracting the security policies out of application layers into middleware [19]. Our OGSA based design will help applications securely participate in VOs without changes to the application layers.…”

A major problem facing organizations using gridcomputing models is the reluctance to participate in multiorganizational collaborative environments due to security concerns, such as unauthorized access, and fair resource usage. The Joint control of Virtual Organizations (JoVO) framework enables organizations to form a unified VO, with jointly agreed, knowable and enforceable security policies. The JoVO framework is based on the fault and intrusion tolerant joint control of identity, attributes, and access control policy through the use of threshold-based certification authorities. We propose a set of agents, the Credential Management Agent and Identity and Authorization Agent to aid grid services when operating in a multi-domain environment. One of the key areas of concern in grid computing is the assurance of all parties involved that security policies are appropriate and will be enforced. We propose an automated distributed audit agent framework consisting of white-box and black-box service testing for joint validation of access control policy.
