Digital Technologies Have Risks

Sustainable Development Goal 16 (SDG 16), introduced by the United Nations in 2015, aims to provide people with safe, fair, and fear-free societies. The UN is an international organization founded in 1945, committed to maintaining peace and security, developing friendly relations among nations, and promoting social progress, better living standards, and human rights worldwide. SDGs are a set of 17 global objectives adopted by UN member states in 2015 as part of the 2030 Agenda for Sustainable Development. They cover a broad range of interconnected issues such as poverty, inequality, climate change, and peace. The main target of SDG 16 is to promote peaceful environments, where conflicts and disputes are kindly resolved. It emphasizes the importance of eliminating all forms of violence, especially against children. SDG 16 also aims to ensure that groups of people and countries have equal rights, an identity, and that they are protected by law. By enforcing those important values among individuals, organizations, and countries, SDG 16 will ensure a healthy society [1].

Information and communications technologies (ICT), like social media platforms, messaging apps, and online shopping websites, play an important role in our lives. We now live in a so-called digital environment—but this environment can sometimes be unsafe. Users of ICT might face multiple threats, like cyber-bullying, which is a form of violence, or theft of their private information, which threatens their safety. Therefore, cautious ICT usage is crucial to achieving SDG 16.

Risks Related to ICT Usage

More and more people of all ages are using technology for many kinds of activities. In many schools, students use websites and emails for education and communication. Mobile applications are used for purposes including entertainment, training, and tracking physical activity. Friends connect on social media to share their experiences. Some meet on gaming platforms. Although these tools are beneficial, they come with many cybersecurity and safety concerns that you should be aware of as a young ICT user.

From the cybersecurity perspective, there are three main concerns to look out for. The first is when information that should be kept secret, like passwords, is disclosed to other people. This is much like a stranger who somehow has a copy of your house key or who is trying to use your identity cheat on an exam. This is called a confidentiality issue. Second, when files and documents, such as study reports, are changed without the consent and awareness of the owner. Think of a situation in which a classmate messes up your project without you knowing it. This is an integrity issue. Third, when your devices cannot be used properly anymore because they are being used by people who are not allowed to use them. This is known as an availability issue.

How do these cybersecurity issues show up in our everyday lives?

Websites and Email Boxes

We use websites and email boxes every day to accomplish tasks, interact with one another, or learn things. Although engaging, some websites can damage our devices or show us inappropriate content. For instance, if you click on a suspicious object, you might be redirected to another website—perhaps one that shows unsuitable content. In other situations, after clicking, malware can be downloaded to your device. Depending on its nature, malware can cause various kinds of damage [2].

Malware may damage your data, for example by erasing the content of your files. Or it may impact confidentiality by allowing access to sensitive information, such as your identity information, home address, or bank details. Some types of malware target availability by consuming all the resources (like processing power and storage space) we have on our devices. For example, a trojan horse is a well-known kind of malware that can give hackers access our devices (Figure 1). You can imagine those hackers as cyber thieves, trying to take things that do not belong to them in the digital environment. Those things can be photos, passwords, or even a country’s important security documents, if they invade a government device.

Mobile Applications

Many ICT users download applications onto mobile phones. Games and activity-tracking apps are popular ones. Although those applications may seem to be safe, some of them may contain malware, often in the form of auto-clickers. An auto-clicker is a simple malware that imitates the user’s actions and clicks on many places at once (Figure 2). This causes our devices to use a lot of resources, making them slow at performing tasks. Auto-clickers can also click on download buttons and download more malware to our devices, which hackers can then use to access our information. Sadly, applications with malware are common. For instance, out of 56 mobile applications found to have malware, 24 were children’s applications [3].

All these security threats may affect our safety in the digital environment, put our money in danger, and damage our ability to access vital services. When you think about this at the country level, and how it can impact the overall safety, integrity, and privacy of citizens’ data, it is easy to understand that cybersecurity directly impacts how safe, fair, and strong a society can be.

How Can Science Help?

Fortunately, many people are working together to make the digital environment safer. Cybersecurity researchers work on protecting the digital world against threats. They develop ways to detect and stop malware before it causes any damage. They also try to figure out who is responsible for the bad actions, such as identity theft. To strengthen the security level of ICT, researchers also work on things like authentication, which means verifying the identity of users to ensure they are who they claim to be, or access control, such as limiting who can access certain resources or data.

As an example of one of our research projects, we set out to create software that could prevent damage to ICT systems even in the face of harmful events. In other words, we wondered if we could build a software that could protect devices from any malicious activities [3, 4]. The software has two main components, a detection component and a recovery component. You can think of the detection component as a policeman and the recovery component as an ambulance rescuer. Much like a policeman, the detection component continuously keeps an eye on what is happening in the device and checks for any unusual activities. This is called monitoring. When the detection component suspects something is wrong, it raises an alarm for immediate attention and action. The alarm instantly triggers the recovery component, which repairs any possible damage, to bring the device back to a healthy state (Figure 3).

This is similar to a real-life situation in which a policeman calls an ambulance after an accident occurs. The ambulance rescuer collects important information from the police and works to understand the damage and rescue injured people. By testing our software with simulated threats, we found that it successfully detected the threats and could repair the damage caused by our mock-attack! In a nutshell, we built a digital hero to safeguard our digital environment.

Enjoying a Safe and Secure Experience While Using Our Devices

Several institutions are putting plans in place to help people use ICT safely. For instance, the International Telecommunication Union (ITU) - the specialized agency from the United Nations for digital technology - provides a series of guidelines on how to minimize the risk and protect children while using ICT’s [5]. It prohibits websites from getting children’s personal information without the agreement of their parents [6].

To keep yourself safe while enjoying the ICT universe, you should be aware of the risks and acquire good behaviors. Be cautious when accessing and using websites and email boxes; only access websites that are suggested and approved by teachers/parents; not download files from unknown senders; limit the number of downloaded applications on your devices; and, finally, tell your teachers/parents about any abnormal or offensive behaviors, such as cyber-bullying or hate messages.

Conclusion

ICT can be a wonderful resource for learning, working, and having fun. However, these technologies can also carry threats that endanger everyone’s safety. In this article, we told you about some of those threats and summarized some ways that the research community and institutions are working on making ICT safer and more secure. We also provided some basic precaution tips you can use for fear-free ICT usage. By ensuring everyone uses ICT safely, we can keep everyone protected and able to enjoy a safer and happier life, in strong and trusted countries—just like SDG 16 envisions. We hope you become more aware of cybersecurity and share its importance in keeping our societies safe.
