According to a recent Statistica report, the number of Wi-Fi® connected devices being used globally is projected to grow to 22.2 billion in 2021. This expansive growth in Wi-Fi adoption not only includes consumer Wi-Fi usage, but it also includes Wi-Fi usage in the Industrial Internet of Things (IIoT). In fact, global management consulting firm Bain & Company predicts that IIoT will grow into a $200B market by 2021, according to its 2019 Beyond Proofs of Concept: Scaling the Industrial IoT report.

The Bain report cites that the main adoption barriers to Wi-Fi in IIoT are implementation risks, including technical expertise and integration, including system and data transition and data portability risks. Among the barriers to IIoT Wi-Fi adoption is ensuring secure Wi-Fi roaming in challenging industrial IoT environments, including the growing number of devices that rapidly move among access points, such as robots, forklifts, hospital equipment and test instruments.

Security Challenges to Successful IIoT Wi-Fi Deployment

In order to successfully and securely deploy wireless devices in IIoT applications, there are multiple domains that must be considered including:

• Secure Boot: This includes securing the device itself, which requires implementing the right capabilities to prevent unauthorized firmware from being deployed.
• Access Control: End-to-end encryption is necessary to secure the data transmission from the device to the access point.
• Certification Storage: Wireless connections need to be secured, which requires Enterprise Security standards (802.1x).

Solution: Lantronix Fully Certified, Secure Wi-Fi Modules and Security Suite

Powered by the Cypress embedded security software suite (CYW43907/CYW20707), the Lantronix xPico270 is an embedded IoT gateway solution with 802.11ac Dual-Band Wi-Fi System-on-Chip and embedded application processor (see sidebar).

Among this solution’s security benefits are:

• Secure Boot:
  • Ensures that only trusted firmware runs on the device
  • Establishes a root of trust for secure identification of servers and the device itself

• Access Control:
  • Allows for multiple users, each with a role that gives different access rights
  • Admin level, which is the only level that can configure users
  • Allows users to have different privilege levels and passwords, limiting their access to applicable data while protecting sensitive configuration changes

• Certification Storage:
  • TLS certificates required to encrypt data sent to servers and to identify devices with client certificates for certain enterprise security standards
  • Storage for certificates, which are securely stored in xPico 200 flash
  • Ability to store multiple certificates for secure communications with multiple servers
  • Updates for certificates that can be updated via standard configuration methods (e.g., via ConsoleFlow™ or over the air)
