A Web service is an autonomous unit of application logic that provides either some business functionalities or information to other applications through an Internet connection. A business process contains a set of activities, and service locators assign an appropriate Web service for each activity.Recently IBM proposed a new XML language called Web Services Endpoint Language (WSEL) for describing endpoint properties of Web services. Web services will be described through endpoint properties by the appropriate extensibility elements in WSEL in order to facilitate the processes of matchmaking and delegation.It is obvious that security issues are important endpoint properties at Web services.This paper extends the WSEL to specify the conflict of interest in the processes of matchmaking and delegation as one of the endpoint properties.In addition to this, this paper also introduces the concepts of separation of duties and security risk factor in the Web service assignments.
