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, where mobile devices and other integrated hardware components are primary targets, to application-based risks, where malware, spyware, and other malicious software are leveraged by attackers to disturb user applications or gather critical user information. The back-end platform comprises the cloud servers, data storage systems, virtual machines, hypervisor, and protocols needed to facilitate cloud services. On this platform, security threats chiefly target mobile cloud servers. Network-based mobile security threats are aimed towards the Radio Access Technologies (RATs) that interface mobile devices to the cloud. Cyber-attacks in this group include Wi-Fi sniffing, DoS attacks, and session hijacking.
