Future Research Challenges of Secure Heterogeneous Industrial Communication Networks

A growing concern of cyber threats towards industrial plants has prompted industrial practitioners to focus on secure communication solutions which can protect their systems from vulnerabilities and as well as their brand image. The security concerns and the solutions for industrial communication networks have become well-discussed topics in research communities. Despite a huge research effort in the area of industrial communication network security, there are several issues that need to be addressed properly such that a unified security solution can be adopted in the industrial domain.In this article, we aim to outline the research direction for industrial communication security. Though security is considered as an on-going process, the major issues that still need to be addressed are trust management for heterogeneous networks, managing network performance with security requirements, usable security and key management.
