Security For Service Oriented Architectures

Web services technologies are advancing fast and being extensively deployed in many di?erent application environments. Web services based on the eXt- sible Markup Language (XML), the Simple Object Access Protocol (SOAP), andrelatedstandards,anddeployedinService-OrientedArchitectures(SOAs) are the key to Web-based interoperability for applications within and across organizations. Furthermore, they are making it possible to deploy appli- tions that can be directly used by people, and thus making the Web a rich and powerful social interaction medium. The term Web 2.0 has been coined to embrace all those new collaborative applications and to indicate a new, “social” approach to generating and distributing Web content, characterized by open communication, decentralization of authority, and freedom to share and reuse. For Web services technologies to hold their promise, it is crucial that - curity of services and their interactions with users be assured. Con?dentiality, integrity,availability,anddigitalidentitymanagementareallrequired.People need to be assured that their interactions with services over the Web are kept con?dential and the privacy of their personal information is preserved. People need to be sure that information they use for looking up and selecting s- vicesiscorrectanditsintegrityisassured.Peoplewantservicestobeavailable when needed. They also require interactions to be convenient and person- ized, in addition to being private. Addressing these requirements, especially when dealing with open distributed applications, is a formidable challenge.

Based on the paradigm of model-driven security, the authors of this book show how to systematically design and realize security-critical applications for SOAs. In a second step, they apply the principles of model-driven security to SOAs.

This complete guide to security for web services and SOA considers the malicious user story of the abuses and attacks against applications as examples of how design flaws and oversights have subverted the goals of providing resilient business functionality. It reviews recent research on access control for simple and conversation-based web services, advanced digital identity management techniques, and access control for web-based workflows. Filled with illustrative examples and analyses of critical issues, this book provides both security and software architects with a bridge between software and service-oriented architectures and security architectures, with the goal of providing a means to develop software architectures that leverage security architectures.

Service-Oriented Security is complex and hard. This books helps business managers understand that implementing security in a service-oriented architecture environment is a journey and not a project. This will allow the organization to reap the benefits of SOA and optimize the business for success.

This book examines both application and security architectures and illustrates the relationship between the two. Supplying authoritative guidance through the design of distributed and resilient applications, it provides an overview of the various standards that service oriented and distributed applications leverage to provide the understanding required to make intelligent decisions regarding their design. The book reviews recent research on access control for simple and conversation-based web services, advanced digital identity management techniques, and access control for web-based workflows.

Software services are established as a programming concept, but their impact on the overall architecture of enterprise IT and business operations is not well-understood. This has led to problems in deploying SOA, and some disillusionment. The SOA Source Book adds to this a collection of reference material for SOA. It is an invaluable resource for enterprise architects working with SOA.The SOA Source Book will help enterprise architects to use SOA effectively. It explains: What SOA is How to evaluate SOA features in business terms How to model SOA How to use The Open Group Architecture Framework (TOGAF™) for SOA SOA governance This book explains how TOGAF can help to make an Enterprise Architecture. Enterprise Architecture is an approach that can help management to understand this growing complexity.

Endorsed by all major vendors (Microsoft, Oracle, IBM, and SAP), SOA has quickly become the industry standard for building next-generation software; this practical guide shows readers how to achieve the many benefits of SOA Begins with a look at the architectural principles needed to create successful applications and then goes on to examine the process for designing services and SOA implementations Each stage of the design process has an accompanying chapter that walks readers through the details and provides helpful tips, techniques, and examples The author team of SOA practitioners also provides two unique, comprehensive, end-to-end case studies illustrating the architectural and design techniques presented in the book

Securing access to information is important to any business. Security becomes even more critical for implementations structured according to Service-Oriented Architecture (SOA) principles, due to loose coupling of services and applications, and their possible operations across trust boundaries. To enable a business so that its processes and applications are flexible, you must start by expecting changes both to process and application logic, as well as to the policies associated with them. Merely securing the perimeter is not sufficient for a flexible on demand business.
