A user's transactions with modern networks and services pro duce a vast amount of user related data. The byproduct of every phone call a person makes or every web page one visits is translated into a log record with usage data. By studying these log records, the user's behavior is revealed and one may come up w ith clues about user preferences, identify security issues , or discover fraudulent use of the network or the service one provides. Thus, the modeling of network users' behavior may serve as an in valuable tool for the IT manager. In this paper, many of these issues are discussed and emphasis is given on the construction of appropriate user behavior representation in telecommunications. As an example, the application of two clustering techniques is presented, with the task to identify appropriate user behavior representation s (profiles) inside a large organization's telecommunicati ons network, in order to spot fraudulent usage. Through this study a researcher and/or the organization's network manager may gain more insig ht into the problems of user profiling and fraud detection.
