Today cities are growing bigger and faster than ever before. This results in various negative aspects for the citizens such as increased traffic, pollution, crime and cost of living, just to name a few. Governments and city administrations and authorities are in need to find solutions in order to alleviate these drawbacks. Over the past years one solution arose and has grown continuously was the concept of the smart city.
The concept of smart cities is based on the application of connected systems to manage a city efficiently. There are various aspects in which smart cities emphasize such as transport control, energy and water transport or public health and safety management. The broad distribution of Internet of Things (IoT) technologies favors the development of smart cities. IoT devices are considered the backbone of a smart city as they function as sensors and can be applied in many environments.
In some environments today’s cities are already really smart. For example, many large cities are using a traffic and transport control system, which can control the flow of traffic and make it more efficient, reducing or even avoiding congestion and increase traffic flow. Smart cities are becoming reality. But as the smart city technologies touching more and more aspects of the citizens everyday life, these technologies drawing increased attention from cyber attackers. Since many of the smart city technologies control safety-critical systems like the already mentioned traffic and transport control system, those systems are worthwhile and, because of the security concerns about the underlying IoT technology, often weak targets.
