Firstly, this is not an original piece of work. It's a collection of whitepapers written by other people. Second, the vaguely worded Amazon description is not accurate. A more accurate description appears in the forward:
"This book concerns security aspects of SOAP-based Web services [through a collection of whitepapers]. The core of SOAP security is a set of WS-* specifications--including WS-Trust and WS-SecureConversation--built on the security header defined by WS-Security. This core was introduced by IBM and Microsoft in a 2002 white paper. Again, from the outset the emphasis is on interoperability."
Lastly, this book has almost nothing to do with what the vast majority of the Internet considers to be web services and focuses solely on SOAP based services, XML and similar ilk. If you're a physicist, mathematician or other academic type and have been asked to write a business to business SOAP based service, this book is probably ideal. Otherwise, don't waste your money.
