Security for a Web Services architecture will need to propose a shift in the traditional understanding of security to accommodate new models for supporting the finding and execution of services in an open dynamic Web environment.

Agassi said that SAP is well-positioned to continue to be a trusted partner during the newest wave -- the Web services wave. "Increased flexibility and speed are the business requirements that will be served as customers begin their migration to services-based solutions," said Agassi. "This next wave of innovation will be enabled not just by the technology infrastructure but by agreement on a common language of business, which will give customers the ability to change processes very rapidly to address their growing needs. SAP is working to deliver both the infrastructure and the common business semantics to enable global businesses to operate."
