Secure design
Secure design of IoT devices and systems is only one component in the overarching IoT security lifecycle. The following diagram shows the design aspects of the lifecycle which will be discussed now. Other aspects of the lifecycle will be discussed in Chapter 4, The IoT Security Lifecycle.
Safety and security design
We've already introduced the need for threat modeling within IoT device and system developments. Now we will expand on additional safety and securing engineering processes to incorporate into your development and integration efforts.
Threat modeling
The IoT security lifecycle is bound to the systems development process. Planning for secure operations of an IoT system should begin while the system is being designed, and as new components of the IoT system are being considered. We therefore consider threat modeling as a key component in any security lifecycle. This is especially true given the iterative nature of the lifecycle, since threat models should always be...
