The Wireless and mobile devices, and their applications often run on different platforms, which can make integration problematic. Enterprise-service-bus (ESB) approach and service-orchestration platforms through mobile agents might offer good solutions. However, the centralized ESB introduces serious limitations and the federated ESB architectural pattern conquers those limitations by partition...

Client software for modern service-oriented web architectures is often implemented as mobile code applets made available by service-providers. Protecting clients from malicious mobile code is therefore an important concern in these architectures; however, the burden of security enforcement is typically placed entirely on the client. This approach violates the service-oriented paradigm. A method...

Web services technologies change the software industry drastically by developing and integrating enterprise web services and applications in order to enable the users to access them. There are several research initiatives in the field of Web services for enterprise applications. However, none of the initiatives have attempted for web applications pertaining to academic institution using Web ser...

Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...

Current Grid Security Infrastructure using PKI based on SSO. Trust is hard to establish in a service-oriented grid architecture because of the need to support end user SSO and dynamic transient service. Open Grid Service (OGS) Security Infrastructure in Global Grid Forum will extend use of Grid system or services up to business area using XML Web Service security technology. This paper describe...

This paper presents an analysis of security aspect of Web-Based applications that utilize Service Oriented Architecture (SOA). The architectural solutions which address security requirements are examined and compared with other quality attributes relevant to web-based systems. More specifically, a trade off analysis in which security is the main focus is performed to select an architecture that...

The Service Oriented Architecture (SOA) became a dominant paradigm for enterprise computing. The web services are the implementation of SOA that works for heterogeneous platforms as they use common Internet protocols for communication and simple text format such as XML for data representation. The basic SOA architecture does not contain any security solution within it and the security is applie...

With the prevalence of loosely coupled web service composition in the service oriented infrastructure, distributed security management has become important to offer flexible web security. In our project affiliated with NatureServe [2], we developed a XACML [3, 4] policy oriented security system to provide trust data service to 75 network partners in the Natural Heritage Program [1]. A Horn Logi...

The promising features of Web services also make them vulnerable to new types of security threats. Web service providers must assure their clients’ confidentiality, integrity and availability over a trusted relationship that may be asynchronous and that may involve multiple business partners. Despite the continued significance of the traditional approaches to securing content, transmission and ...

The Semantic Web’s success will depend on the implementation and use of Web service, becoming preeminent in E-commerce, which will likely be agent-based in the future. Agents use the large amount of information available over the web, but it will allow agents more subtle attacks. Agents and supporting technologies need to be secure and reliable for safe Web service as they adopt more mission cr...
