ABSTRACT:
A system and method for preventing fraudulent calling activities of computer data systems such as a Private Branch Exchanges (PBX) accessed through dial-up telephone lines via a remote maintenance or administration port. The system is readily adaptable to existing PBX systems without the need to alter PBX hardware or software configurations. The system includes a device to passively monitor calling activity conducted through the remote port of the PBX without alerting the caller in order to detect a condition of activity indicative of fraud. The monitoring device may include rule based expert system software to analyze call transmission data for activities outside the norm that are indicative of fraud. Alternatively, the monitoring device may include software or hardware for comparing call digit origination data to a database of authorized call activity contained within the monitoring device. Upon the indication of a fraudulent call, the system causes the disconnection of the call from the PBX to minimize economic loss to, PBX customer and telecommunication service provider.
