Practical Internet of Things Security

By: Drew Van Duren, Brian Russell

Overview of this book

With the advent of Internet of Things (IoT), businesses will be faced with defending against new types of threats. The business ecosystem now includes cloud computing infrastructure, mobile and fixed endpoints that open up new attack surfaces, a desire to share information with many stakeholders and a need to take action quickly based on large quantities of collected data. . It therefore becomes critical to ensure that cyber security threats are contained to a minimum when implementing new IoT services and solutions. . The interconnectivity of people, devices, and companies raises stakes to a new level as computing and action become even more mobile, everything becomes connected to the cloud, and infrastructure is strained to securely manage the billions of devices that will connect us all to the IoT. This book shows you how to implement cyber-security solutions, IoT design best practices and risk mitigation methodologies to address device and infrastructure threats to IoT solutions. This book will take readers on a journey that begins with understanding the IoT and how it can be applied in various industries, goes on to describe the security challenges associated with the IoT, and then provides a set of guidelines to architect and deploy a secure IoT in your Enterprise. The book will showcase how the IoT is implemented in early-adopting industries and describe how lessons can be learned and shared across diverse industries to support a secure IoT.

IoT IAM infrastructure


Now that we have addressed many of the enablers of identity and access management, it is important to elaborate how solutions are realized in infrastructure. This section is primarily devoted to public key infrastructures (PKI) and their utility in securing IAM deployments for the IoT.

802.1x

802.1x authentication mechanisms can be employed to limit IP-based IoT device access to a network. Note though that not all IoT devices rely on the provisioning of an IP address. While it cannot accommodate all IoT device types, implementing 802.1x is a component of a good access control strategy able to address many use cases.

Enabling 802.1x authentication requires an access device and an authentication server. The access device is typically an access point and the authentication server can take the form of a RADIUS or some authentication, authorization, and accounting (AAA) server.
