摘要

A Web service is defined as an autonomous unit of application logic that provides either some business functionality or information to other applications through an Internet connection. Web services are based on a set of XML standards such as Simple Object Access Protocol (SOAP), Universal Description, Discovery and Integration (UDDI) and Web Services Description Language (WSDL). The benefits of adopting Web services over traditional business-to-business applications include faster time to production, convergence of disparate business functionalities, a significant reduction in total cost of development, and easy to deploy business applications for trading partners. However, security concerns are the major barrier that prevents many business organisations from implementing or employing Web services. This paper discusses one of the classical security policies that deal with Conflict of Interest (CIR) - the Chinese wall security policy. In the example of financial applications, this paper then extends this concept into specifying and implementing conflict of interest assertions in the newly developed WS-Policy. WS-Policy is an XML representation that provides a grammar for expressing Web services policies, to allow service locators to have a common interpretation of security requirements for the matchmaking process between Web services and activities. By using C# in .Net framework, this paper also describes a prototype Web service called "CIRDetector" for supporting conflict of interest assertions discussed in this paper.
