Security and Privacy Issues in Cloud, Fog and Edge Computing

The advent of technologies like IoT and 5G brought a new computing paradigm called cloud computing into the world. Cloud computing has become the main platform for data warehousing and processing. However, storing data into the cloud has its own set of challenges and security concerns. Moreover, with increasing data being generated from each device; the traditional cloud computing paradigm has become ineffective in addressing problems like high latency, bandwidth limitation, and resource limitation. So, new computational paradigms like edge and fog computing are proposed to solve the former's issues at the device itself or near the device. Both these paradigms provide computing and memory storage options close to the device itself. Despite their advantages, no system is perfect. In this paper, I list down the different privacy and security problems in all three computing paradigms and their proposed solutions.
