A certification-aware service-oriented architecture
No full textThe widespread development of Service-Oriented Architecture (SOA) and web services is changing the traditional view of information technology. Today, software applications are increasingly distributed and consumed as a service, and business processes are implemented by selecting and composing services provided by different suppliers at run-time and with a minimal human intervention. In this scenario, where services are usually selected on the basis of clients’ functional preferences, the risk of providing powerful but insecure applications raises, and the problem of guaranteeing and preserving the security of services and business processes becomes stringent. To this aim, we put forward the idea that security certification techniques can be adopted to provide the evidence that a service system has some security properties and behaves as expected. However, existing security certification techniques are not well-suited to the service scenario, since they are designed for static and monolithic software and then cannot support the intrinsic SOA dynamics. In this chapter, we discuss recent developments in the area of extending security certifications to web services. In particular, we first review current certification approaches, and highlight requirements and challenges for applying them to the service ecosystem. We then present an advanced methodology for security certification based on testing, as a crucial part of a novel approach for security certification developed in the context of the FP7 EU project Advanced Security Service cERTificate for SOA (Assert4Soa)
Advanced Web Services
No full textWeb services and Service-Oriented Computing (SOC) have become thriving areas of academic research, joint university/industry research projects, and novel IT products on the market. SOC is the computing paradigm that uses Web services as building blocks for the engineering of composite, distributed applications out of the reusable application logic encapsulated by Web services. Web services could be considered the best-known and most standardized technology in use today for distributed computing over the Internet. This book is the second installment of a two-book collection covering the state-of-the-art of both theoretical and practical aspects of Web services and SOC research and deployments. Advanced Web Services specifically focuses on advanced topics of Web services and SOC and covers topics including Web services transactions, security and trust, Web service management, real-world case studies, and novel perspectives and future directions. The editors present foundational topics in the first book of the collection, Web Services Foundations (Springer, 2013). Together, both books comprise approximately 1400 pages and are the result of an enormous community effort that involved more than 100 authors, comprising the world's leading experts in this field.Athman Bouguettaya, Quan Z.

Towards a two-layered framework for managing web services interaction
No full text© Copyright 2007 IEEE – All Rights ReservedThis paper discusses the use of a framework for analyzing the interactions that arise between Web services engaged in composition. For the sake of achieving better coordination and avoiding conflicts, this framework assigns interactions to two layers known as business logic and support. The business-logic layer comprises control and transactional flows, whereas the support layer comprises exception and message flows. Additional features of this framework include the use of context to oversee interaction progress between Web services and a set of policies to constrain the behavior of these Web services.Maamar, Z., Benslimane, D. and Sheng, Q.Z
Smart Adelaide guide: A context-aware web application
No full textContext-aware Web services are currently emerging as an important technology for building innovative context-aware Web applications. Unfortunately, context-aware Web services are still difficult to build. This paper describes Smart Adelaide Guide, a context-aware Web application developed by ContextServ platform, a research project sponsored by Australian Research Council. ContextServ adopts model-driven development where a UML based modeling language - -ContextUML - -is used to model Web services and its context-awareness features. The platform offers a set of visual editing and automation tools for rapid generating and deploying context-aware Web services. © 2010 ACM.K. Liao, Q.Z. Sheng, J. Yu, H.S.
