Effective Cyber Security Strategies for IIoT Industrial IoT in the industry sector: Trust and Scalability

Abstract

There has been great growth in the use of IoT. It is a modern technology and is becoming increasingly popular. It is also widely used in industrial sectors where it is referred as Industrial IoT (IIoT). Although the technology can provide great benefits, it also leads to some challenges. In this thesis we will explore the security characteristics of IIoT used in industrial sectors. We will determine why and if there is a correlation between trust and scalability in IIoT infrastructure. In order to do this we will be using qualitative methods for data collection and have performed both interviews and simulations. We also use systematic literature review is used to structure and review the literature. We performed a synthesis of all the data combined from literature review, interviews and simulations inorder to provide an explanation to security aspects and trust with scalability. We discover that there is some contradiction between the results of the security aspects used in real world and the ones in literature. The relationship between trust and scalability was also discovered to strong. Trust in IIoT devices is needed to scale a network. The multiple ways you create trust is also discussed and can be done in multiple ways. The scalability is also affected by the topology of a system. As a result of our findings we will suggest some guidelines for establishing trust and scalability in IIoT infrastructure.
