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.

Authentication credentials


IoT messaging protocols often support the ability to use different types of credentials for authentication with external services and other IoT devices. This section examines the typical options available for these functions.

Passwords

Some protocols, such as MQTT, only provide the ability to use a username/password combination for native-protocol authentication purposes. Within MQTT, the CONNECT message includes the fields for passing this information to an MQTT Broker. In the MQTT Version 3.1.1 specification defined by OASIS, you can see these fields within the CONNECT message (reference: http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html):

Note

Note that there are no protections applied to support the confidentiality of the username/password in transit by the MQTT protocol. Instead, implementers should consider using the transport layer security (TLS) protocol to provide cryptographic protections.

There are numerous security considerations related...
