A Fog Network-based Approach for Security of IoT Applications

Fog Computing is a term made by Cisco that insinuates extending cloud computing to the edge of a network. Fog computing supports the operation of Fog/cloud, storage, and networking services between end devices and conveyed processing data centers. While depending on the fog network will enhance the performance by eliminating the upper layer between IoT devices and Cloud servers by making users and devices closer to the servers. But as users become closer to the servers and data centers, attackers also become closer too, this will make the fog layer subjected more to attack and the data centers will be dangerous. Now fog computing faces new-fangled security and assurance defies other than those procured from cloud computing. In this paperwork, we will list the types of attacks that affect the Fog network and we discuss the available solution, moreover, we will illustrate our new method to protect this layer from the attacks which will introduce a new security layer between IoT devices and fog network to detect and prevent the attacks from reaching the fog layer, in addition, we will protect the fog layer from blocking when an attack is presented.
