Advances in information technology depend on the availability of telecommunication, network and mobile technologies. With the rapid increasing number of mobile devices being used as essential terminals or platforms for communication, security threats now target the whole telecommunication infrastructure that includes mobile devices, radio access network, and the core network operated by the mobile operators. In particular, the mobile core network is the most important part of the mobile communication system because different access networks are consolidated at the core network. Therefore, any risks associated with the core network would have a significant impact on the mobile network regardless of technologies of access networks are in use. This paper reviews the security risks in the mobile core network for data services by considering the confidentiality, integrity and availability (CIA) aspects, and then relates them to the ITU-T X.805 reference framework. Finally, this paper provides a recommendation on how to address these risks using the ITU-T X.805 reference framework. This paper will benefit mobile operators and network designers looking to secure the mobile packet core system.
