Dennis has 25 years experience in IT and has worked in a diversity of business environments, like government, utilities, insurance companies and large manufacturing multinationals.

His current job is Lead Architect in the group Strategy and Innovation Management, within the office of the CIO of Philips International. His current projects are focused on the architecture and implementation of infrastructure standards, e-Invoicing and several aspects of SOA (metadata repositories, governance).

Dennis has always been interested in implementing new concepts in an innovative way, especially in distributed computing environments. In 2000 Dennis designed and implemented an Enterprise level intermediate infrastructure between heterogeneous integration solutions for Philips. This domain-based architectural design was the foundation for the concept and introduction of the Enterprise Service Bus (ESB) by Sonic Software.

Presentation
SOA Security Challenges in an Extended Enterprise Model

This presentation focuses on issues related to identity and access management as traditional enterprises move into an extended enterprise model, based on SOA concepts. Usually the resulting architectures are a mix of eBusiness portals with an enterprise internal SOA and a strong and inflexible set of legacy components. As a consequence, identities must be managed across all domains and legal/regulatory requirements adhered to. Although solutions exist for most parts of the overall puzzle, the resulting architecture presents considerable challenges for governance and operations.

Philips and CGI have joined forces in a pilot project that involves some out of the box thinking and which we hope will result in a greatly simplified but generalizable solution for these issues.
