Securing Device Connectivity in the Industrial Internet of Things (IoT)

The Internet revolution has produced fundamental changes in the way we work and communicate. It has enabled any-to-any connectivity. This connectivity has evolved through various stages. At the first stage, we saw user locations (homes and offices) connected with business locations through wired Internet connections. At the second stage, mobile user devices (laptops, smartphones, and tablets) are connected to businesses and each other using wireless Internet connections. The transformation brought by the Internet is moving forward and the next target is intelligent connected devices. Today, we see the latest stage of connectivity where intelligent devices connect people, businesses, and other diverse intelligent devices using a mix of wired and wireless Internet connections. These devices need beyond imagination capabilities in order to successfully interact with other device in the real world. The Internet of Things (IoT) expects to bring more profound changes in the world around us, and to do so, the IoT must come up with solutions and strategies to respond to the pressing issues of device connectivity including security, availability, and reliability. This chapter provides a review of various IoT connectivity protocols and analyzes their security capabilities. The chapter also provides some specific recommendations.
