A Brief Review on Security in IoT Environments Based on Fog Computing Architecture

The Internet of Things (IoT) is an innovative technology that encompasses the connectivity of physical, intelligent objects to the Internet, enabling the collection, sharing and analysis of data. Currently regarded as one of the revolutionary technologies of the 21st century, the significant increase of IoT devices and the huge amount of data they produce at the network's edge has led to the Cloud Computing (CC) paradigm being over-loaded. Consequently, new computing paradigms are emerging, such as Edge Computing and Fog Computing (FC). Although these paradigms offer different functionalities and improve Quality of Service (QoS), they also introduce huge risks in terms of data security and privacy. This paper presents a brief review on security in IoT environments based on Fog Computing (FC) architecture, with particular attention to security measures such as authentication, confidentiality and data integrity. Furthermore, it addresses attacks targeting these measures, in order to avoid or reduce security issues in Fog Computing-IoT environments.
