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 keys and certificates


Keys and certificates provide identities to IoT devices, gateways, and other components and enable secure data in transit across IoT systems. Although most organizations have existing agreements with PKI providers for Secure Sockets Layer (SSL) certificates, the provisioning of certificates to IoT devices frequently do not fit the typical SSL model. PKI service providers such as GlobalSign and Digicert have begun tailoring their certificate offerings towards the IoT. Another option however is the stand-up of an in-house PKI.

Device certificates chain up to root certificates, also known as trust anchors. These trust anchors are provisioned to devices and enable trust within an organization. There must be processes in place to manage these trust anchors. For example, deleting trust anchors that may have been compromised or adding new trust anchors to extend trust.

Certificates must also be actively managed. Certificate lifetimes should be limited (for example,...
