The evolution and integration of technologies such as IoT, big data, the cloud, and smart cities transform the way we live and work. However, despite the many benefits, this evolution also brings along challenges. One of the main concerns to be taken into account is security. With the rapid evolution of technology, it is of primary importance that we take a step back to consider the origin of key threats. Thinking about the possible threats will help to prevent possible risks. The rapid development of technology brings along new considerations. Therefore, when implementing these technologies into smart cities there needs to be a certain level of preparation. This will help encounter new threats and risks.

Smart cities need to be prepared for the following threats and risks:

    Smart grid attacks that can be the origin of a blackout.
    Traffic congestion or accidents – these can be accessed by hackers through smart traffic systems and affect all of the city’s transportation.
    Attacks against the city’s wastewater sewer system – this can cause pollution within the water to spread dangerous and contagious diseases across the city.
    Attacks against smart trash cans – this can bring issues in the public health sector.

Vulnerability in Security

According to the interview given to eGovinnovation, Mr. David Siah, says that currently, every aspect of the security of a smart city are still vulnerable. Especially as the infrastructure is utilized by the wider population. Therefore, the emphasis should be on protecting these systems (power generators and water networks). Due to the considerable impact that this could have on the city’s population and society.  According to Mr. David Siah, it is important that governments take into consideration the gap between the old and new generation of threats. It is therefore recommended that cities set up cyber security enforcement agencies. This will help to ensure the safety of the smart cities. An example other cities can learn from is Singapore, who has set up its Cyber Security Agency (CSA) which oversees the nation’s cyber security strategy, landscape and education.
