Summary:
|
Communication Service Providers(CSPs) interconnect their networks through Network Network Interface(NNI) and the relations between the network entities are regarded as trusted based on the closeness and isolation of the network. Interconnection between network entities of different CSPs is also trusted based on the commercial contracts or agreements rather than security technologies. Security measures and policies on NNI are usually not implemented due to this trusted relationship. Nowadays, telecommunication networks are more and more open. Under such circumstances, signalling for controlling and management may be abused, resulting in theft or fraud of sensitive information related to the user, such as calling line identification (CLI), international mobile subscriber identity (IMSI) and location information, etc. Furthermore, short message service (SMS) and calls of users may also be under surveillance illegally.
