This book explains how to implement secure Web services and includes coverage of trust, confidentiality, cryptography, authentication, authorization, and Kerberos. You'll also find details on Security Assertion Markup Language (SAML), XML Key Management Specification (XKMS), XML Encryption, Hypertext Transfer Protocol-Reliability (HTTP-R) and more.

WS-Security defines how security tokens are contained in SOAP messages, and how XML Security specifications are used to encrypt and sign these tokens, as well as how to sign and encrypt other parts of a SOAP message. In practice, this means defining the XML elements and attributes that are used to enclose tokens into SOAP messages, and the means to enclose XML Signature and XML Encryption into SOAP. This chapter uses the Web Services Enhancements 1.0 for Microsoft .NET (WSE) for hands-on familiarity with WS-Security.
