Multi-Tenancy Cloud-Enabled Small Cell Security

The anticipated technological advancement of 5th Generation (5G) network is the ability to apply intelligence directly to network's edge, in the form of virtual network appliances through the archetypes of Network Functions Virtualisation (NFV) and Edge Cloud Computing. The adoption and use of innovative technologies, such as Software Defined Networking (SDN) and NFV is the key to making 5G networks more promising. However, implementing these technologies yield to the imaging of new security challenges. A Cloud-Enabled Small Cell (CESC) provides multi-operator platform to integrates and execute at the virtualised environment. Providing services to multiple operators/tenants to access technologies and protocols in unified network architecture requires well-define security approach in order to deliver secured data communication, privacy and integrity. The CESC security requirement analysis was carried out using Secure Tropos (SecTro) methodology. The paper will thoroughly examine the CESC security challenges and provide possible solutions to mitigate those challenges.
