The use of different cloud computing technologies increased with the rise of 5G technology and IoT. Cloud computing also enabled intense data processing and warehousing. Data storage in the cloud comes with several issues and security concerns. Moreover, when the volume of data created by every device increases, the conventional cloud computing architecture fails to address concerns such as excessive latency, bandwidth limits, and resource constraints. As a result, new computational paradigms such as edge and fog computing have been proposed to address the former's issues. Both of these paradigms offer computation and memory storage alternatives. Regardless of their benefits, implementing these technologies introduces many new privacy and security issues. This work presents a list of security and privacy concerns, as well as dangers, that exist in all three computing paradigms: cloud, fog, and edge computing.
