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.

Review

From the reviews of the third edition:

“It is encouraging to encounter a textbook for undergraduate students that is devoted to information age ethics … . This third edition contains three new chapters. … I appreciate Kizza’s work in the ethical education of information technology (IT) students. … Overall, I recommend this very basic … but significant educational topic as an introductory text.” (Brad Reid, Computing Reviews, December, 2008)

Product Description
Rapid advances in computing and information science often outpace society’s ability to adapt its moral and legal codes. Different computing paradigms applied to the same ethical issues can often lead to conflicting confusions.

This second edition examines ethical, social, and policy challenges stemming from the emergence of cyberspace, the convergence of telecommunications, and other information handling products. The book broadly surveys thought-provoking questions about the impact of these new technologies, with particular emphasis on the growth of the Internet, artificial intelligence, cyberspace, and virtual reality.

Topics and features:

* Describes how changes in information technology influence morality and the law.

* Surveys the history of computing and the recent evolution of computer crimes

* Incorporates recent requirements for computer science curricula

* Assess workplace concerns related to privacy, surveillance, and virtual offices

* Contains numerous discussion and research projects on all presented material

* Considers what should be covered in a professional code of conduct of IT professionals

* Offers a pertinent discussion on civil liberties, harassment, and discrimination..
