Towards a Systematic Survey of Industrial IoT Security Requirements: Research Method and Quantitative Analysis : research method and quantitative analysis

Industry 4.0 and, in particular, Industrial Internet of Things (IIoT) represent two of the major automation and data exchange trends of the 21st century, driving a steady increase in the number of smart embedded devices used by industrial applications. However, IoT devices suffer from numerous security flaws, resulting in a number of large scale cyber-attacks.

In this light, Fog computing, a relatively new paradigm born from the necessity of bridging the gap between Cloud computing and IoT, can be used as a security solution for the IIoT. To achieve this, the first step is to clearly identify the security requirements of the IIoT that can be subsequently used to design security solutions based on Fog computing.

With this in mind, our paper represents a preliminary work towards a systematic literature review of IIoT security requirements. We focus on two key steps of the review: (1) the research method that will be used in the systematic work and (2) a quantitative analysis of the results produced by the study selection process.

This lays the necessary foundations to enable the use of Fog computing as a security solution for the IIoT.
