This book promotes Quadrasis EASI security kit (like a UserGuide) which made me so annoying! It does not provide practical examples from industry leading security vendors like Netegity TransactionMinder, SunONE Identity server etc.
If you are looking for implementing XML Security using Netegrity TransactionMinder, Microsoft Passport, SunONE Identity server..then this book is a WRONG CHOICE. You may find this book more appropriate if you are a Quadrasis user.
The first part also has a good introduction into the building blocks for WS security solutions, including not only SOAP and XML security, but also security of the underlying middleware technologies. Here, they could do a better job on going into more details about WS-Security spec and its friends. In the second part, they show how to use those building blocks together. Again, chapters on security of Java-based WS and the security interoperability lack a good structure and some times are just confusing.
From reading the book, it became clear to me that WS security is yet another instance of the old problem of enterprise security integration, although with a SOAP twist. Therefore, many methods from middleware security can be used for securing WS applications. I would recommend reading this book only to those who build complex heterogeneous WS applications.
Some previous reviews of this book thought that EASI was exclusively a description of the product from the authors' company. I didn't see it that way -- in fact, I didn't see any specific details describing vendor products based on EASI. I viewed EASI more as an architectural technique that can be applied to many vendor products. Different Web Services vendors of Service Oriented Architectures (SOAs) offer frameworks that look like EASI, which makes this book useful when evaluating those alternatives.
Dr. Carrington whose uncompromising work ethic drives away the woman he loves; Dr. Savage, brilliant GYN doctor with the morals of a "savage" alley cat and Dr. Merrick, Chief of Surgery, has a do-as-I-say, not-as-I-do behavior problem.
The story blends the secret lives of these three men into an intriguing drama of love, lust and revenge. Written in the '70's and still a dramatic presentation.
