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.

Managing firmware and patching updates


Patching and updates concern how software and firmware binaries are provisioned to IoT devices. Most legacy and even some new systems require direct connections (for example, USB, console, JTAG, Ethernet, or others) to locally and manually update a device to new versions. Given the migration to cloud-based monitoring and management, many newer devices have the capability to update or patch software over the network from the manufacturer or dedicated device/system manager. Severe vulnerabilities are possible in software update and patching workflows; therefore, in the device engineering process, it is crucial that the following be supported in any over-the-air patching capability:

  • End-to-end software/firmware integrity and authentication from the build system through any staged transit to the device (in many cases, confidentiality may also be needed)
  • The software/update process should only be performed via a special access function that is only available...
