Dear authors,

I've been looking at the notion of virtual organizations lately, and the need for service aggregation calls for secure mechanisms such as identity management, trust, secure federation overall.
How would you envisage a secure mechanism for aggregating dynamically services? Can VOs be securely achieved reasonably?

Thanks!

You can create secure virtual organizations via aggregated (web) services. If you look at the case study in Chapter 14 we discuss parts of this. If you go through the whole book you should come out with all the knowlege to construct secure VOs, but it is more than I can address in this forum.

In addition to what Chris pointed out...I wanted to highlight couple of things.

The book has extensive coverage on Identity Management using SAML, XACML, XKMS and Liberty Alliance standards to support "Federated Identity" architectures.
These standards technically serves as the basis for establishing "Virtual Orgs". Refer to Chapter 7, 12 and 14. The Case study does demonstrate security design for a Web based portal that aggregates SOAP based Web services and J2EE applications from multiple partners.
