- Safety: The system must not harm the world
- Security: The world must not harm the system
Thus it is clear that the IoT and IoT security are much more complex than traditional networks, hosts and cybersecurity. Safety-conscious industries such as aircraft manufacturers, regulators, and researchers have evolved highly effective safety engineering approaches and standards because aircraft can harm the world, and the people in it. The aircraft industry today, like the automotive industry, is now playing catch-up with regard to security due to the accelerating growth of network connectivity to their vehicles.
