Abstract

As cloud computing is not viable for many Internet of Things (IoT) applications, fog computing is an emerging technology that inherits cloud computing platform and addresses the need for IoT and industry IoT. It reduces the time taken for communication between IoT and the cloud and substantially reduces the bandwidth that affects the IoT performance. The incorporation of IoT applications in fog paves way for a high chance of vulnerabilities in fog. So, the fog layer requires more security to protect the data both in transit and rest. Hence, the security issues of fog computing and the existing solutions are revealed in this chapter. It has been concluded that fog computing provides better performance than its counterparts like Edge Computing, Cloudlet, and Micro-Datacenter. This chapter investigates major security issues in fog computing and provides possible solutions and security recommendations to meet IoT security goals.
