Service-oriented infrastructures pose new challenges in a number of areas, notably with regard to security and dependability. BT has developed a combination of innovative security solutions and governance frameworks that can address these challenges. They include advances in identity federation; distributed usage and access management; context-aware secure messaging, routing and transformation; and (security) policy governance for service oriented architectures. This paper discusses these developments and the steps being taken to validate their functionality and performance. In contrast to traditional infrastructures, in which resources that were scaled to meet peak demand were dedicated to particular applications on a permanent basis, SOIs exploit virtualisation to the full, allocating resources to applications in a way that constantly matches supply with demand.
