A Glance into the Future: The Security and Privacy Challenges (Cyber Attacks) of Smart Cities and How to Overcome Them

Smart cities are already prevalent throughout the world. With various data, algorithms, and sensors, urban centers are optimizing functionality to improve the lives of the inhabitants. With smart city technology, you can interact and live without the hassles. That makes the cities more efficient, reduces resources, offers more services, and much more.

The push for smart city integration is inevitable. Companies use data in every facet of their business. Therefore, it’s just a matter of time before the world governments embrace this approach and apply those technologies in everyday life.

Despite the many advantages that come from a smart city, there are many cautions to consider, too. There’s tons of personal information collected from citizens on their mobile device options. This brings up the risk of privacy issues and cybersecurity problems.

What Is a Smart City?

The exact definition of the smart city is blurred because there are various technologies and approaches considered to be smart. In a sense, they’re cities that leverage IoT to optimize functions. This is especially true when collecting information from a user’s device, analyzing it with algorithms, and using it in various ways.

They want to take advantage of the latest developments in technology along with data insights. This approach can improve the lives of everyone, boost efficiency and productivity, cut back on consumption of energy resources, enhance adaptability, reduce costs, and more.

In fact, the UN has estimated that two-thirds of the entire population should be living in cities by 2050, which is up from about half in previous years.

Though the benefits are plentiful, there are various concerns about smart cities. These include cyber security attacks, data breaches, and infrastructure problems.

What Are the Four Types of Cyber Attacks?

There are primarily four types of cyber-attack including:

  • Malware attack
  • Phishing and Spear Phishing attacks
  • Credential stuffing
  • Brute-force attacks

Cyber security focuses on all of those, and an intelligence service is essential to protect the cities. However, this requires each city to have plenty of security officers within the network and infrastructure. These people are always connected to the resources of the city, and therefore, they must be trustworthy.

How Does a Cyber Attack Happen?

In a sense, cyber attacks happen when cybercriminals try gaining access to electronic data illegally, which is stored in a network or computer infrastructure. They are often successful in gaining information without proper authorization. The information they get can include passwords, Social Security numbers, and other data.

What Are the Advantages and Disadvantages of Smart City?

There are various economic and practical benefits of smart digital technologies and smart cities. However, there are also concerns. Here are some of the advantages:

  • Ability to make data-based decisions effectively
  • Better transportation services
  • Safer communities
  • Efficient public services
  • Reduction of the city’s environmental footprint
  • Increase digital equity
  • New economic development options
  • Infrastructure improvement

With that, though, come a few disadvantages:

  • Limited privacy – There are intelligence systems and digital security cameras everywhere, so anonymity is challenging.
  • Social control – With the ability to centralize and track data, the person handling that information has more power. If in the wrong hands, it can be used for manipulation and control.
  • Excess network trust – You must put the entire city on networks and electronics, so they are always connected.

What Are the Potential Cyber Security Challenges Faced in Securing Smart Cities?

City administrators are tempted by the possibility of controlling and monitoring processes and assets remotely throughout their districts. This means they’re already implementing smart technologies throughout a wide host of services. These include utilities, traffic control, transportation, and street lighting.

However, with more connectivity comes the greater risk of a successful cyber attack on the city’s electricity grid. That could knock out power to the entire area for an extended period. With that, companies can’t operate, residents don’t have heating, cooking facilities, and lighting, and much more.

Plus, IoT (Internet of Things) sensors are often used in these smart cities to notify refuse collectors to pick up trash. Those are taken down because there’s no electricity. The result is that trash piles up, creating a significant public health risk.

On top of the physical impact of the cyber attack, such systems must run on huge amounts of data. This is another tempting target for would-be thieves.

Again, a smart city must be connected at all times, so information gets where it needs to go. The easiest way to do that is through the IoT and other network solutions. They can facilitate rapid communication between servers, data-collecting devices, and their points of action.

Data is sent to central servers to make decisions or to other smart mobile devices that can influence the actions. In a sense, it’s like the body’s physical nerves, which directs information where it must go.

In a sense, the information is all stored on the cloud, which is highly secure. However, that doesn’t mean cybersecurity is easy. Hackers can still get into these systems and affect other related software. Sometimes, they do that with no one knowing, including the government.

With that, there are various data streams coming together to tell people what’s going on in the city. Real-time data is combined with historical information to make better decisions. This can include local traffic and much more. Relevant info is fed into algorithms to decide on the right action with human operatives available, too.

Ultimately, this approach can offer solutions to various problems and enhance things. Cities figure out the best time for traffic lights to turn green or when streetlights should brighten up because people walk by.

Risks

The smart city does have risks, even though the benefits and improvements that technology brings are beneficial. The most prominent concern is cybersecurity, especially if a malfunction or attack causes a full system failure or a large-scale data breach.

Hacker Attacks and Failures

Smart cities often combine various aspects that make them vulnerable. They’re centralized, so integration is key, and they’re connected to the internet. Such online access gives a window of opportunity to attackers, who can access those vital systems and services. Integration and centralization open up the door to do significant damage to the infrastructure, even when it’s in the cloud.

In the past, those system options were usually offline, and the infrastructure (power grids) were localized, so it was almost impossible to cause a mass destruction without widespread violence or invasion.

Though hackers could infiltrate one power plant, it wasn’t a widespread threat to the existence of the city, and now it is. These malicious threats focus primarily on integration, which means more services and infrastructure are opened up for attack. What’s more, hackers don’t have to be in the same country to hurt a business through computers.

Such attacks can come from sophisticated gangs, but the biggest threat is actually from nation-state groups that want to stop everything and cause disruptions related to the city and local government.

You may not think that traffic problems could be that damaging, but the risks far outweigh the advantages if enough people are injured or hurt. With that, it can all be done by a mobile device anywhere in the world. It might taint the drinking water, cause train delays, and so much more.

Though no one wants to dissuade the world from using smart city technology, it must be emphasized that cybersecurity is crucial for a smart city development. You can’t build a smart world without keeping it secure, or you might end up with chaos.

Data Breaches

Smart cities include the harvesting, storage, and analysis of huge data amounts related to individuals. From their location throughout the day to the personal data stored on government platforms, it is sensitive and highly valuable to attackers.

The most extreme smart city visions could involve surveillance of every interaction to build up profiles of people being monitored. If that data ever gets leaked or stolen, it poses a significant threat to those related to the problem.

If the person’s location is exposed, it could reveal their entire schedule. Thieves might use such information to rob the house, stalk their moves, and even more malicious things. With that, leaked data causes identity theft, which could drain the bank account and so much more.

Given how much data is collected from the smart city, there are tons of ways to take advantage of such technology and harm others. Securing smart cities is possible, but cyber solutions and cyber intelligence have to be on point and perfect to do that. The cloud and IoT technologies are required to handle cybersecurity and prevent an attack.

Why Smart Cities Pose a Risk to Privacy

Risks to privacy are another concern for urban smart cities. If the information falls into the wrong hands, the privacy risk is significant. However, what happens when the data is where it should be, pushed through different algorithms and stored in databases in the cloud? Smart cities have a potential to collect tons of data through various services and devices connected to the cloud that can be used to impact different things.

With the IoT sensors, the data could end up under the government’s control or a private company. These places have various software technologies and service options to protect them and keep them secure on the network.

Typically, it is stored in the cloud or on network computers. Various smart city initiatives are conducted through public-private partnerships are launched solely from private companies.

Since the world is still in its infancy relating to privacy law and many countries don’t have regulatory frameworks for it, we aren’t sure what data can be collected, when, or under what conditions.

Why Worry about Privacy and Security?

Cyber connectivity brings about tons of malicious people and various challenges and threats. Though most people focus on making these smart cities secure, you must also consider that people also have the mindset of “don’t do anything wrong and have nothing to hide.” Privacy doesn’t really focus on what you’re doing; it’s more about the right you have to it. Cyber attacks are prevalent, even now without a smart city. Online attacks happen every day, and people often worry about their information being protected. You use mobile technology with your smart device to provide secure solutions and often connect to the cloud.

However, the cloud isn’t completely secure. You’re not under surveillance at all times right now, and the government doesn’t have full control over your life. Connectivity threats and being online can change that and impact certain things, but it’s not all about the digital challenges.

There’s a moral code that smart cities might violate where privacy is concerned.

The IoT network is there for a reason. IoT means Internet of Things, and it pertains to the networks of physical objects – those that are embedded with software, sensors, and all the rest. Typically it’s in the form of devices, and a cyber attack is prevalent.

The severity of the Threat

Now that you know cyber issues are prevalent, it’s important to find the right cyber solutions to keep the smart city secure and safe. This requires each device to be protected if it might be added to the digital framework or networks of the city itself.

While cyber security primarily focuses on the cloud, there are other secure software options and resources available in the digital space. It is possible to mitigate the risks, but it requires that all devices be secure, each area within the city has a local service, and attacks are watched for and stopped immediately.

It is easy to compromise smart cities, so security is often the thing focused on most. However, this also relates to management, device access, service options, and so much more.

Mitigating Risk

To ensure that people reap the benefits of smart cities without putting security at risk, administrators must focus on a cybersecurity-first approach. It’s essential to train and recruit security specialists who understand the cyber concerns and offer cyber services.

Administrators should also focus on implementing appropriate processes and using the right security services with the right technological advancements. That way, they have visibility of what’s going on in the system and can keep it secure and safe.

Security teams must know everything that’s going on and offer management solutions that meet the needs of the smart cities. Armed with the right information security professionals can prevent an attack by understanding where the vulnerabilities are and removing them from the physical system.

Management then continues on each device to provide appropriate service wherever possible. More analysis must be done so that there’s no compromise on smart technology versus safety and security.
