utilizes cloud-based data storage

Moreover, the 5G network doesn’t have many physical boundaries as it utilizes cloud-based data storage and NFV. Thus, 5G operators may have less direct control of the data storage in cloud environments. As different service providers, companies, and even countries have different data privacy mechanisms depending upon their preferred context, privacy could be at risk depending on location. Because the cloud computing systems contain various resources shared internally amongst users, there is the possibility of a user spreading malicious traffic to pull down the performance of the entire system, consume more resources, or secretly access resources of other users. Likewise, in multi-tenant cloud networks, where tenants manage their own control logic, interactions can trigger conflicts in the network configurations. Mobile Cloud Computing (MCC) transfers the concepts of cloud computing into the 5G ecosystems. This could introduce several security vulnerabilities that could surface with the architectural and infrastructural modifications in 5G. The open architecture of Mobile Cloud Computing and the versatility of mobile terminals develop loopholes via which cyber attackers could launch threats and breach privacy in mobile clouds.

MCC threats can be classified as front-end, back-end, and network-based mobile security threats. The front-end of the MCC architecture refers to the client platform, which comprises the mobile terminal on which the applications and interfaces needed to access the cloud facilities operate. The threat landscape in this part may range from physical threats
