Fog Security and Privacy
The Security and Privacy issues in Fog are quite different from those in the cloud. Data is better protected in Fog servers than in the IoT devices themselves. This chapter delves into the challenges of Fog Security and Privacy at three levels; (a) Authentication at IoT device level, (b) Encryption of data between the IoT device and Fog server and (c) Man-in-the-middle attacks. In addition, the possible failure recovery and backup mechanisms are presented.
