Significance of intruder detection techniques in the context of industry 4.0

Abstract

With the advent of Industry 4.0, many physical systems are transforming into cyber-physical systems (CPS). As these CPS are connected to the internet, have a lot of vulnerabilities. There is a need to protect them from cyber-attacks. This is true across domains. Many cyber-attacks are being reported in the literature. These cyber-attacks had devastating effects. The cyber-attacks not only result in an economic loss but also resulted in the loss of effort and inconvenience. Hence a complete understanding of the type of cyber-attacks and predicting the behavior of intruders is very much important for protecting CPS. Though many cyber-attacks are reported across multiple domains, the type of attacks is unique about each domain. This makes solving security problems even more difficult. What is also observed from the literature review is that the security infrastructure that is available today may not be secure for tomorrow. This clearly shows the complexity of solving the security problems- Intrusion detection system(IDS). Hence, an effort has been made in this work to consolidate different types of attacks reported across multiple domains. This is valuable not only for academicians but also for researchers and practitioners, as this paper contains not only the work reported so far but also provides future directions for promoting further research in the area of intruder detection.
