Vulnerabilities in fog/edge computing from architectural perspectives

Abstract

Recently, the emerging IoTization paradigm generates a tremendous amount of heterogeneous data offloaded from digital devices to networks. The heterogeneity of these big IoT data requires the networks to expand their computational capability from the cloud to the edge, realizing a new fog/edge computing (FEC) system. The FEC system provides multiple satisfactory levels in terms of performance, latency, security, etc. to user devices according to service demands. Because the FEC system is in between the cloud and user devices, this supplemental part introduces several vulnerabilities on both north and south interfaces as well as among internal FEC components. This chapter analyzes open security and privacy issues in FEC from architectural perspectives. First, a comprehensive overview of computational cloudization is presented, which leads to a hierarchical computing architecture in the network. From that, vulnerabilities within each architectural model, such as intrinsic FEC, the standard reference FEC architecture, FEC virtualization, and FEC integration into the 5G network, are discussed in detail. Finally, we summarize the chapter in the last section. © 2021, Springer Nature Switzerland AG.
