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.

Authorization and access control


Once a device is identified and authenticated, determining what that device can read or write to other devices and services is required. In some cases, being a member of a particular Community Of Interest (COI) is sufficient; however, in many instances there are restrictions that must be put in place, even upon members of a COI.

OAuth 2.0

To refresh, OAuth 2.0 is a token-based authorization framework specified in IETF RFC 6749, which allows a client to access protected, distributed resources (that is, from different websites and organizations) without having to enter passwords for each. As such, it was created to address the frequently cited sad state of password hygiene on the internet. Many implementations of OAuth 2.0 exist, supporting a variety of programming languages to suit. Google, Facebook, and many other large tech companies make extensive use of this protocol.

The IETF ACE working group has created working papers that define the application of OAuth...
