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.

Defining system roles 


IoT systems can oftentimes require complex access control frameworks. Consider the types of devices and types of users who will operate within your system and define a set of roles that will be granted access to various aspects of IoT system administration and operation. In the following example, roles are defined and include multiple roles for devices (such as, privileged versus regular gateway) and users:

Role

Definition

Gateway

Allows communications with IoT devices and other authorized services. 

Privileged Gateway

Allows standard gateway functions in addition to being able to manage devices (create/delete/update).

Device

Devices that can perform routine operations. They can participate in /publish/subscribe protocol interactions.

Privileged Device

Devices that require elevated privileges (for example, a first-responder vehicle moving through an intersection).

Management Application

Allows for management of IoT devices including firmware updates and configuration management...
