The IoT (Internet of Things) has become a reality and is gradually entering new fields and sectors.
This harbours both opportunities and risks. Intelligent networking of embedded systems can save resources and provide significantly improved functionality and added comfort. The potential vulnerability of the systems is risky, because even devices that were previously independent are now connected to the Internet and (often permanently) interlinked.
Security is often insufficient, and a single weak point can be used to paralyse or manipulate entire processes. For this reason, security has to be taken into consideration even before “things” are networked, i.e. at the device design stage.
