Enzo Peduzzi defines a smart city as a city that strives to use its resources efficiently and has a high level of safety and security so the city will be resilient in case of accidents.

He also says we need smart cities because of the increasing urbanisation.

"A smart city works like a city today; it just has more intelligent transportation systems, uses energy in a better way, and is able to recover quickly in case of an accident. If the population inside the city feels safe and secure, it is a smart city", he says.

As more and more devices are being connected to the internet, he stresses that cyber security is a big risk for smart cities.

Enzo Peduzzi says: "This is one of the biggest challenges we have, not only in smart cities but everywhere. The hackers do not sleep, but I am confident that if we take the cyber security part and the physical security part into account, we can manage this in a proper way."
