Security in a SOA

Sat, 14 Apr 2007 16:15:00 EDT

As the name suggests, a Service Oriented Architecture is one where application functionality is packaged as autonomous services that adhere to industry standard interfaces (WSDL, SOAP), and the services are then deployed in an IT architecture that makes for their most effective use.

Any enterprise that wants to take full advantage of the business opportunity represented by 'e-services' will focus on moving the Internet beyond merely accessing data to accessing a rich array of electronic services. E-service offerings will need to blend content, transactions, and information in compelling new ways, many of which have yet to be invented.
