Practical Internet of Things Security - Second Edition

By: Brian Russell, Drew Van Duren

Overview of this book

With the advent of the Internet of Things (IoT), businesses have to defend against new types of threat. The business ecosystem now includes the cloud computing infrastructure, mobile and fixed endpoints that open up new attack surfaces. It therefore becomes critical to ensure that cybersecurity threats are contained to a minimum when implementing new IoT services and solutions. This book shows you how to implement cybersecurity solutions, IoT design best practices, and risk mitigation methodologies to address device and infrastructure threats to IoT solutions. In this second edition, you will go through some typical and unique vulnerabilities seen within various layers of the IoT technology stack and also learn new ways in which IT and physical threats interact. You will then explore the different engineering approaches a developer/manufacturer might take to securely design and deploy IoT devices. Furthermore, you will securely develop your own custom additions for an enterprise IoT implementation. You will also be provided with actionable guidance through setting up a cryptographic infrastructure for your IoT implementations. You will then be guided on the selection and configuration of Identity and Access Management solutions for an IoT implementation. In conclusion, you will explore cloud security architectures and security best practices for operating and managing cross-organizational, multi-domain IoT deployments.

Configuring gateway and network security


IoT systems consist of multiple gateways, networking protocols, and even physical mediums. Edge devices may connect to each other within a Wireless Sensor Network (WSN) using short-range protocols such as ZigBee and Z-Wave, while gateways connect to the cloud over IP connections using messaging frameworks, such as MQTT or REST. Securing an IoT system requires a comprehensive evaluation and lockdown of the gateways and networking components of the system. 

Securing WSN 

WSNs can consist of thousands or more low-power battery-operated sensors that communicate using protocols, such as ZigBee, Z-Wave, Bluetooth, NFC, or Thread. WSNs make use of gateways that can act as translation devices between the short-range RF protocols and IP-based protocols that communicate with the cloud. Security administrators must consider the secure configuration of the devices and protocols used within WSNs, as well as how to manage securely keys used within WSNs.
