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.

The need for software transparency

Software transparency provides development teams with a solid understanding of the components within their products. 

As of the time of writing, there are efforts to enhance the transparency of software through efforts such as the Software Bill of Materials (SBOM), led by the National Telecommunications and Information Administration (NTIA). An argument can be made that having an IoT product SBOM is a side-effect of having good development processes in place. 

Transparency also provides a valuable tool within the software supply chain. Providing users with an understanding of the third-party libraries used within a product can provide those users with important security knowledge.

For example, the OpenSSL Heartbleed vulnerability discovered in 2014 resulted in a worldwide, catastrophic security hole exposing the majority of the internet's web servers (read more at https://en.wikipedia.org/wiki/Heartbleed). Many companies did not even know about their exposure...
