ABSTRACT
This chapter examines some of the common types and the ways in which they can be investigated. It should be remembered that telecommunications networks are, primarily, businesses and they are subject to all the 'normal' fraud types that any organization faces. The telecommunications industry has been one of those most affected by the developments in technology during the last 30 years. Depending on the nature of services offered there is always the possibility that telecoms businesses will need to become authorized for financial services and will need also to be able to demonstrate their ability to monitor transactions. The industry was then faced with a loss of confidence in its products and began, hastily, to retro-fit security measures such as RF fingerprinting and to introduce fraud management systems to identify the use of cloned equipment. Prepaid fraud is extremely likely and common. The service centres upon the ability of the network to differentiate between handsets which are pre- and post-paid.
