“…We propose a security model to off-load the security functions, such as VPN and IPv6, the protocol to an internet-facing device, and cluster the IoT sensory environment behind a firewall using Network Address Translation (NAT) to access the IoT using IPv4. However, there are many VPN-based security solutions reported in the literature as each development model varies with the application environment and is not a simple and straightforward solution [10,11,24]. Recently, even in the IoT context, many different ways of implementing the VPN technology are reported [25,26].…”

“…Hence, the configuring and customizing of OpenVPN needs to be given a unique consideration for different situations. It is also reported in the literature that the VPN fails to comprehend the more advanced and complex threats to the system [24][25][26]. The scope of this paper does not engage in exploring the limitations of the VPN protocol.…”

“…We need a practically viable end-to-end security model that can enforce the principles of security, privacy, and trust throughout the entire IoT system lifecycle, including the design, implementation, and operational phases [22,23]. In addition to the security burden of a Virtual Private Network (VPN) based deployment, 50 billion devices cannot be supported with IPv4 directly, as well as IPv6 with its additional support requirements that are essential for internet-facing devices [24]. All these requirements and inherent IoT resource limitations must be given due consideration for a successful and secure deployment of any large-scale IoT infrastructure in the real-world.…”

“…Recently, in the IoT context, many ways of implementing VPN technology have been reported, and each research work has been developed with a different context [24][25][26]. However, the main concerns reported in such studies are lack of adaptability, flexibility, interoperability, scalability, and low-cost viability for deploying a secure large IoT infrastructure.…”

“…We believe this is an important step in the realm of IoT and Industry 4.0 towards realizing the smart cities of the future. While there are several methods to use VPN in IoT as a common engineering practice, performance and latency are inherent issues with VPN for large-scale deployments in real-world environments [5,24]. Another important aspect to consider in the practical world is its increasing cost and complexity associated with scalability.…”

Recent growth in the Internet of Things (IoT) looks promising for realizing a smart environment of the future. However, concerns about the security of IoT devices are escalating as they are inherently constrained by limited resources, heterogeneity, and lack of standard security controls or protocols. Due to their inability to support state-of-the-art secure network protocols and defense mechanisms, standard security solutions are unsuitable for dynamic IoT environments that require large and smart IoT infrastructure deployments. At present, the IoT based smart environment deployments predominantly use cloud-centric approaches to enable continuous and on-demand data exchange that leads to further security and privacy risks. While standard security protocols, such as Virtual Private Networks (VPNs), have been explored for certain IoT environments recently, the implementation models reported have several variations and are not practically scalable for any dynamically scalable IoT deployment. This paper addresses current drawbacks in providing the required flexibility, interoperability, scalability, and low-cost practical viability of a secure IoT infrastructure. We propose an adaptive end-to-end security model that supports the defense requirements for a scalable IoT infrastructure. With low-cost embedded controllers, such as the Raspberry Pi, allowing for the convergence of more sophisticated networking protocols to be embedded at the IoT monitoring interface, we propose a scalable IoT security model integrating both the IoT devices and the controller as one embedded device. Our approach is unique, with a focus on the integration of a security protocol at the embedded interface. In addition, we demonstrate a prototype implementation of our IoT security model for a smart water monitoring system. We believe that our modest first step would instill future research interests in this direction.
