This week saw the techUK host a workshop on securing the Internet of Things and overcoming the risks associated with an increasingly connected world. The event (#IoTSecurity) attracted a variety of speakers from the public and private sector and brought about some interesting topics and further questions on this ever changing landscape.
Embedded Device and Host Device Life Cycle Disparity
Stephen Pattison from ARM, introduced the event, and brought up and interesting view of the challenge with keeping IoT devices up to date - either with firmware, software or hardware improvements. He observed there is often a disparity between the small inexpensive sensor, actuator, or controller type components and the host device with respect to life span. For example, a car may last 15 years, whilst a tracking component may last 36 months. The rip and replace nature of general consumerism has subtle issues with respect to the IoT landscape, where the re-provisioning of new embedded devices, or the improvement in existing devices is often overlooked.
