Abstract
Innovative technologies such as cloud computing systems provide global cooperative services for end users and medium-large companies. Fog computing extends cloud computing storage networking and computing capabilities to edge and backbone servers on the cloud for Internet of Things (IoT) devices, to optimize efficiency with low latency, location awareness, and geographical distribution applications. One of the considerable difficulties facing fog computing systems is security and privacy challenges. This survey reviews current fog computing system architectures, their features, security challenges associated with IoT devices, and existing countermeasures, in order to guide researchers to find comprehensive solutions to reduce the security risks related to fog computing systems.
