Alan Gray wrote a detailed article “Protecting IoT devices from cyberattacks: A critical missing piece». One approach to IoT security is to build protection directly into the device. Before selecting an IoT security framework, it is important to step back and look at the requirements at both device and system levels.
One of the unique tasks of IoT is that the network perimeter is often blurred. Network security devices can protect cloud computing resources and any IoT devices that are within the perimeter of the network, but do little to protect mobile devices or IoT endpoints located in the field. Therefore, while security devices play a critical role in protecting IoT, they do not provide a complete solution.
Ultimately, some combination of hardware and software will be required, but creating software in IoT devices is a critical missing element that needs to be addressed.
This article will be for some guide and help to understand this topic.
