Abstract

The combination of Industrial Internet of Things (IIoT) with Software-Defined Networking (SDN) and Edge Computing (EC) provides industrial environments with enhanced flexibility and scalability and fast communication capabilities. However, the combination of these services also can lead to sophisticated security threats that impact every system element starting from basic IIoT devices up to SDN controllers and distributed edge servers. In this paper, a survey is conducted on SDN-enabled IIoT network security vulnerabilities and weaknesses that occur at each architectural level of edge computing systems. Our study enlists current security countermeasures that use lightweight cryptography and artificial intelligence-based intrusion detection systems and blockchain-based flow integrity verification methods and identifies knowledge deficits to direct future development of industrial security systems that provide both strong protection and fast response times.
