Security and Privacy Issues and Solutions for Fog

This chapter presents an overview of the primary security and privacy issues in fog computing. It discusses the state‐of‐the‐art solutions that deal with fog computing‐related security and privacy challenges. The chapter also discusses the major attacks on fog‐based Internet of Things (IoT) applications. It provides a side‐by‐side comparison of the state‐of‐the‐art methods toward secure and privacy‐preserving fog‐based IoT applications. The chapter aims to summarize all up‐to‐date research contributions and to outline future research directions that researcher can follow in order to address different security and privacy preservation challenges in fog computing. Cloud computing suffers from substantial yet unsolved challenges such as large end‐to‐end delay, traffic congestion, lack of mobility, location awareness, and communication cost. Due to lack of centralized and privileged control in security management as in cloud computing, access control becomes a challenging issue in fog computing with heterogeneous and service requirements.
