Rapid technological advancements have resulted in increasingly more efficient and lightweight devices that, coupled with low-power and wide-range wireless connectivity, have given rise to Industrial Internet of Things (IIoT) systems. As a result, the concept of intelligent environments was developed, such as smart airports, where ubiquitous sensors seamlessly cooperate through several types of communication technologies, such as WiFi, BLE, ZigBEE and 5G, enable the collection of data and the dynamic adaption of the system to changing circumstances. However, along with certain benefits, such as augmented communication, enhanced business processes and improved efficiency, IIoT introduces new vulnerabilities, enabling cyber-attackers to compromise not only the digital infrastructure of IIoT architecture-enabled smart airports, but also affecting their physical assets. In this paper, we present a novel smart airport cybertwins security-oriented IIoT testbed, named SAir-IIoT, which comprises multiple heterogeneous IIoT devices and communication protocols, organised into distinct zones, automatically interconnected with each other, that can be remotely accessed as-a-service. To the best of our knowledge, this is the first cybertwins security-oriented testbed that enables researchers and practitioners to remotely practice attack and defence scenarios in smart airport IIoT environments. Additionally, we introduce a new data management technique for dynamically collecting, analysing and tagging heterogeneous data from diverse data sources including IIoT devices and network flows. Finally, we compare SAir-IIoT with other IIoT-based testbeds, revealing its complexity and effectiveness to evaluate new cyber security methods.
