Modern approaches to prevent fraud in mobile communications networks

This article focuses on the effectiveness of modern techniques of fraud prevention in the communications networks. The main security systems used to counteract the fraud, have been considered in the article. The basic methods and approaches (e.g. analysis of individual events, control of the integrity of data flows and analysis of subscriber behavior profiles) to detect and prevent fraud have been reviewed in this publication. The key challenge of fraud counteraction systems and solutions is that information about subscribers is allocated in different systems that might lead to the problem of data synchronization. Fraud detection and prevention approaches, which represent the creation of a single centralized system for managing fraud, are described in the article. The major purpose is to identify the intruders by analyzing an aggregated data from the adjacent anti-fraud systems. This approach, based on the experiences of a number of anti-fraud systems, allows setting rules and patterns to prevent intruders. In addition, a single fraud management system enables the analyst to receive up-to-date aggregated data on an unscrupulous client online.
