Security for Web services and service-oriented architectures

Web services based on the eXtensible Markup Language (XML), the Simple Object Access Protocol (SOAP), and related standards, and deployed in Service-Oriented Architectures (SOA), are the key to Web-based interoperability for applications within and across organizations. It is crucial that the security of services and their interactions with users is ensured if Web services technology is to live up to its promise. However, the very features that make it attractive – such as greater and ubiquitous access to data and other resources, dynamic application configuration and reconfiguration through workflows, and relative autonomy – conflict with conventional security models and mechanisms. Elisa Bertino and her coauthors provide a comprehensive guide to security for Web services and SOA. They cover in detail all recent standards that address Web service security, including XML Encryption, XML Signature, WS-Security, and WS-SecureConversation, as well as recent research on access control for simple and conversation-based Web services, advanced digital identity management techniques, and access control for Web-based workflows. They explain how these implement means for identification, authentication, and authorization with respect to security aspects such as integrity, confidentiality, and availability. This book will serve practitioners as a comprehensive critical reference on Web service standards, with illustrative examples and analyses of critical issues; researchers will use it as a state-of-the-art overview of ongoing research and innovative new directions; and graduate students will use it as a textbook on advanced topics in computer and system security.

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.
