Traditionally the networking architectures used within the industrial domain have been many and varied. With its established enterprise IT roots, Ethernet was always going to be the backbone network of choice to link the worlds of operational technology (OT) and information technology (IT) together. However, since the arrival of Industrial IoT (IIoT), connecting all the production assets, such as sensors, actuators, robots, and the myriad of other equipment, typically involved proprietary, vendor-specific networking. The availability of single-pair Ethernet (SPE) looks set to change this legacy approach.

Wi-Fi 6 is increasingly seen as a complementary to cellular technologies such as LTE-M and even 5G –when it becomes widely available. In private networks, the performance uplift of Wi-Fi 6 over Wi-Fi 5 is substantial and more than sufficient to support innovative use cases such as automated guided vehicles, industrial robots and many other applications.

Among security best practices, system partitioning separates and isolates security-related hardware, software, and data in a “trusted zone” and tightly limits all attempts to access trusted content from outside the zone. Non-secure software cannot directly access secure resources. The Trusted Zone isolates security-related Microcontroller Unit (MCU) hardware, software, and external devices.

Internet of things (IoT) is a network of items embedded with sensors which are connected through the internet [1]. One IoT system consists of computing devices, physical plants and networks defined as a system-of-systems (SoS) [2]. During developing IoT systems, architectural dependencies across the entire SoS are challenged because of the massive compositions among them.

The purpose of this draft paper is to start a conversation about what it means to have confidence in the cybersecurity of IoT devices used by individuals and organizations and the various ways of gaining that confidence. This paper describes the landscape of confidence mechanisms that are currently available for establishing the security of IoT devices in the marketplace. In preparing this paper, NIST conducted extensive research on initiatives that can help to instill confidence in IoT device security and held a series of meetings with government and industry experts to glean information on the unique aspects and challenges in this space.
