This document presents design pattern recommendations for building Grid applications based on the principles of service orientation and using existing Web Services technologies. The design pattern described in this document is a subset of the Web Services Grid Application Framework (WSGAF) approach to building Grid applications since it only focuses on the use of the Web Services Interoperabili...

However, outsourcing introduces new security vulnerabilities due to the corporation's limited knowledge and control of external providers operating in foreign countries. Security of operati...

This paper presents the analysis, design and implementation of security facilities within the edutain@grid infrastructure, to support secure hosting of Real-Time On-line Interactive Applications (ROIA). The edutain@grid project aims to develop a novel, sophisticated and service-oriented Grid infrastructure which provides a generic, scalable, reliable and secure service infrastructure for ROIA. ...

Securing an application based on Service Oriented Architecture provides defenses against a number of threats arising from exposing applications and data to the Internet. A good number of security guidelines are available to apply security in web applications. But these guidelines are sometimes difficult to understand and generate inconsistencies. Security guidelines are often represented as sec...

The Semantic Web is expected to change the way of Enterprises’ operation. This study is focused on a novel secure structure relating in an efficient networking service-oriented architecture for delivering secure Semantic Web Services. It is presented initially all the technical factors (e.g. the associated protocols) and explained the networking architecture. The proposed issues for an appropri...

Web services aiming at spontaneously integrating services from different providers in ensuring at offering a user the best possible experience, face considerable challenges in materialising that notion of improved experience. The interrelationships between the concepts of security, performance and interoperability, while critical to any web service, pose the biggest test and constitute the key ...

In this paper we present the design and implementation of a lightweight security infrastructure, for the federated security, that enables organization to share resources based on the trust federation between several organizations. The infrastructure consists of an augmented security layer placed on top of the Web Service protocol. The solution utilizes the latest WS-Security specifications and,...

Web Service is a reusable component which has set of related functionalities that service requesters can programmatically access from the service provider and manipulate through the Web. One of the main security issue is to secure web services from the malicious requesters. Since trust plays an important role in many kinds of human communication, it allows people to work under insecurity and wi...

Service description in a distributed system allows system components to know about one another and to make intelligent decisions regarding request routing and propagation. The paper discusses service description model used in a distributed system for Web search and search-based advertising. A service description consists of content description (terms), attribute set, and a number of service par...
