Cybersecurity in social networks

Gonçalves, Ricardo Jorge Girante

Abstract

In recent years, the use of social networks has been increasing substantially. As we know, platforms such as Facebook, Twitter, Google +, Pinterest, LinkedIn or Instagram allow millions of individuals to create online profiles and share personal information with several friends through social networks – and, often, it’s possible to do the same with a large amount of strangers. By itself, social networks should not be considered a cyber threat. However, there are several issues related to maintaining the user’s data security and privacy, especially when they upload personal information, photos and / or videos. The large majority of users ignores the security best practices, which sometimes facilitates the hackers’ attacks. The main goal of this research is to understand patterns of information that are revealed on online social networks and their privacy implications. The goal is to map people behaviour on social networks and understand if they care about the security of their data exposed on the Internet. This research also aims to understand the impact of cybersecurity in social networks and a comparison of which social network is most concerned with the exposure of its user. It will be also addressed the current defence solutions that can protect social network users from these kinds of threats.

INTRODUCTION This research aims to contribute to a better understanding of users’ behaviour on social networks. The world’s best-known social networks are investing in cybersecurity, especially now with the entry of the General Data Protection Regulation (GDPR), which is a new European reference text on the protection of personal data, that aims to “give back to the citizens the control of their data while simplifying the regulatory environment of companies” (Union, 2018). The goal is to analyse the user’s behaviour and create a model/ list of best practices that can contribute to better use of the social networks. Cybersecurity in social networks has already been studied, especial by the biggest platforms, such as Facebook and Google. Although most recently, Mark Zuckerberg, Facebook’s chairman and chief executive officer, was involved in legal issues when the Cambridge Analytica company utilized the users’ data of their social networks without their consent. What happened to Facebook is just a small example of what is happening worldwide, many people still use social networks to share everything about their lives and it is necessary to study in detail all the promises that lead people to do such things. 1.1. BACKGROUND AND PROBLEM IDENTIFICATION In the actual world or better digital world, social networks have become part of our daily life. Every day all of us post something on LinkedIn, Facebook, or Twitter and we are sharing our personal information with our friends and with persons that are strangers to us. In the article by Parker (2017), all email users are well-informed about how to handle email security issues, especially the people who deal with work emails every day. For instance, we cannot open emails that seem strange to us and click on unknown links. The malicious methods that are used in emails can also be used in social networks to infect people’s computers and smart devices. Once a single user is infected successfully, the message can be sent back to all that person’s contacts. For example, a link shared by a friend on the social network are more expected to be trusted, but when someone clicks on it there is a high probability that it will be redirected to a malicious website. A recent Symantec’s (cybersecurity firm) research indicates that 65 per cent of spear-phishing emails were used by all of the known groups carrying out targeted cyber-attacks. And 96% of the targeted attacks are carried out for the purpose of intelligence gathering (Symantec, 2019). According to the Benevenuto, Rodrigues et al. (2009), the majority of online video at social networks, such as the world’s most popular – YouTube – that allow users to post videos gives the opportunity to introduce reliable content or even poor-quality content. For instance, when a viral message is spread on WhatsApp, YouTube, Facebook, among others, it can be seen by thousands of people, which can open the “doors” to spammers access to our data. “Content pollution may jeopardize the trust of users on the system, thus compromising its 16 To start, when a user registers in any social network automatically becomes a member and has an associated profile, and from that moment the member of the social network will have the page with his information made available to the other members that can do it a request for friendship (Antunes & Rodrigues, 2018). The member has a list of friends who may or may not grow over time, you can also post posts at your page that can be commented or shared. Each member linked with another user receives all the updates of the posts of each other, ordered chronologically, that is a feed. Members can also identify their friends/ links in their posts. In social networks, there is also the possibility to create groups/ channels according to their interests. In each type of social network, we can verify there are at least one of the three options: Friendship – This type of relationship is done by sending a request for friendship, and the information shared will become available in the feed of both members. Fan – This type of relationship is most commonly used between members and the pages of brands and/ or companies. The member subscribes the page and has access to the content published by the companies through its feed. Follower – In this case, the member can only choose to follow another member, as is the case of Twitter that allows you to follow personalities. It does not imply to send and accept a friend request. It is a unilateral relationship in which the follower does not receive content published by his followers in his feed. The vast majority of social networks have adopted these terminologies, but for example, in the case of Twitter posts, are considered tweets and have a maximum of 140 characters and are classified by several words preceded by a hashtag (#) and republishing a post is called a retweet. 17 3.1.1.2. Social Network Organization Conceptually, a social network is seen as a set of bidirectionally related “members”, according to figure (3). Each of the members is connected directly to others and this link corresponds to a friendship between the two users (Antunes & Rodrigues, 2018). Figure 3 – Social Networks organization. 18 3.1.1.3. Social Network Contents Social networks can cover the most varied formats of content that essentially depend on a set of publication rules defined by each type of social network and the type of content is authorized. As well as the features that are available also vary between each type of network. To illustrate this, below we ca see two images of publications made in two of the most used networks in the world, Facebook and Twitter. Figure 4 – Facebook Post As shown in the figure above, we can observe that a post is divided into the following elements: • Content – Text message and a photograph. • User identification – The post was placed by the user “Cristiano Ronaldo”. • Comments – This post has 13 thousand comments. • Emotions – This post obtained three types of manifestations from 536 thousand users. • Shares – The post in question was shared 9583 times. 19 The above image is from Twitter. In this case, the publication has the name of tweet, and we can identify: • User identification – The post was placed by the user “La Liga”. • Hashtag – The hashtag is “#LevanteBarça”. • Content – The content consists of a short text message. • Retweets – Retweets indicate the number of times this tweet was shared; in this case it was shared only 19 times. Each time you retweet it, it is possible to see the message that accompanies it. • Emotions – This post obtained 74 emotions. 3.1.1.4. Social Communities A Social Community or online community is not built or befriended, but it is a group of people with something in common, where they can share experiences, ideas, goals, shared interests, thoughts, and solutions (usually these networks are non-profit) (Bond, 2020). There are several tools to bring together communities for discussion on topics that a community or network finds mutually interesting or beneficial. “Stack overflow” and “Zwame” are an example of a social community where we can share our doubts, ideas, and solutions for other people. Social communities are online communities that use social platforms, they can include personal communities and communities as they are built using tools such as LinkedIn. As said before an online community it’s a group of people based on proximity and with something in common, like experiences, ideals, goals, or profiles. Figure 5 – Twitter Post 20 In some communities, its users are “invisible”, such as a community that accompanies a blog. In the community that accompanies the blog there is always a central community of believers/ fans of a specific blog and other people who are only interested in a specific subject of that same blog that continue to frequent the site. But most of them will not make any kind of commentary on the published articles. As a way to identify who does not make comments the author of the blog can create forms and mechanisms to offer a voucher, or even a discount on any article in order to retain people to your site. In other communities, it is easier to identify users because they are built on the profile of each user’s interests. In the image below we can see how the inspired vision of an engagement funnel (different types of communities) shows how users interact with brands (Aboulhosn, 2020). According to Bradley and McDonald (2011), the Gartner group has created six basic principles of community involvement for a social community to succeed and enjoy the participation of its users, as mentioned below (figure 7): 1. Participation a. Some companies see social networking as a good opportunity to release some information to focus on the user’s attention. b. The design of social networks becomes the main focus of companies and with this, they sometimes lose the notion that they should focus more on “please” the customer. Figure 6 – Social Media Engagement Funnel. 21 2. Collective a. It’s so easy to get people to join a community and contribute to their growth. b. A plan must be created to be able to “reach” the target audience. 3. Transparency a. Successful communities allow users to see the participation of other users, generating mutual knowledge. b. For this purpose, community network managers provide the means for their followers to evaluate other users' posts, for example by rating the post of other users with stars or allowing feedback from the post to improve communication. 4. Independence a. In social communities, there has to be dependency so that anyone can participate, but for this, the moderator and/ or certain mechanisms can filter which types of users can participate in their sites to avoid generating conflicts. 5. Persistence a. Other great features of community networks are the ability to retain information and interactions among their users. 6. Emergency a. The fact that there is a giant collaboration on the part of its followers also causes certain behaviours to appear gradually as an interaction exists. These behaviours must be regulated but so that the communities themselves have the autonomy to manage themselves by creating productivity. Figure 7 – Six core principles of community participation according to Gartner. 22 3.1.2. Typologies There are several types of social networks, divided into different types and according to their purpose, that will be demonstrated below: 3.1.2.1. Social Networks According to Antunes and Rodrigues (2018), social networks are divided into five categories: • Generalists o Relationship Social Network: This kind of social networking is meant to connect people from all over the world. In fact, the biggest goal of social networks is to create a relationship between users. Among them, there are LinkedIn, Google+, etc. o Professional Social Network: They are social networks that aim to generate professional relationships with other users, by exposing their curriculum and skills, getting leads, jobs etc. As an example, we have the social network LinkedIn the best-know and the most used around the world. o Niche Social Network: Targeting a specific audience, be it a professional category or people who have a specific common interest. The best-known case is TripAdvisor, where users give ratings to places related to the gastronomy and tourism industry. • Multimedia o Entertainment Social Network (Multimedia): The focus of these social networks is not to create relationships between their users, as seen in the point above, their main goal is content consumption. The biggest example of such social networks is YouTube, being the largest video distribution platform in the world, where the goal is to publish and watch videos. 23 • Microblogging o The microblogs provide the origin of blogs, where it is nothing more than a mini version of the original blog, but with fewer features and interface options. These blogs have an average character size of 120-180 per post, not exceeding three lines. As an example, the most popular service in the category is microblogging Twitter with the slogan “What are you doing?”. • Messaging o The Messaging Social Networks are platforms that enable messaging, many of which started around social networking platforms, like Facebook. Facebook Messenger and WhatsApp are the best-known platforms that enable the user to interact with everyone that is on their network. • Games o Like the Messaging Social Network, in this one (Game Social Network) user has the games he bought, and he can chat with anyone on their network. Steam and Origin are the best-known platforms that enable us to play multiplayer games and chat with other users. 24 3.1.3. Vantages and disadvantages Social networks and social communities are already part of people's routines. This “fashion” has made brands and companies also begin to use and interact with their prospects and customers, bringing some advantages and disadvantages to society, such as: 3.1.3.1. Vantages 1. Social networks provide us with great ease of communication, they allow connections with a lot of people, regardless of their location. 2. The search for old friends, family, etc. The social network gives us the possibility to find people who have moved from a long time ago, colleagues and even relatives. 3. Due to a large number of users, social networks provide the possibility that all members discover friends according to their interests and hobbies. 4. Social networks can be well used as Internet ads and, looking at the number of visitors, to very effective ads, bringing incredible possibilities to find good job offers. 5. Being able to participate in discussion groups is another positive aspect of social networks. Some groups gather people interested in exchanging information on a range of subjects, such as illnesses, doubts, courses, books, etc. 6. Companies can have a much more personalized and direct relationship with each client or possible client, since you can contact each one, either to solve problems or give new information. 7. Be able to know more about each of your customers: people share their likes, desires, and other information that can be valuable to businesses when it comes to getting close to their target audience. 8. Real-time information: Social networks allow you to communicate urgent brand messages on an official channel. 3.1.3.2. Disadvantages 1. The information provided in social networks can be used by anyone without the users having any knowledge about it. 2. Contact information can be used for spam. 3. sometimes social networks can even harm families, and users who are very interested in social networks, because they spend all their free time online and do not pay attention to the people around them. 25 4. Parents should monitor what their children are doing in order to prevent them from being victims of malicious people, such as paedophiles. 5. A large number of people cannot spend a day or even a few hours without visiting the social network. The vice of people and the absence of the Internet becomes a disaster and people do not know what to do when cannot access online communication. 6. Dissemination of false information is another problem that occurs in social networks. The spread of false information leads to gigantic proportions, even seriously damaging the victims of such lies. 7. Most people demonstrate their lives on social networks, that is, they tell where they live, to where they travel, where their children study, etc. This information is a gateway to the wrong people who can use this information to plan robberies, kidnappings, etc. 3.2. COMPUTER SECURITY 3.2.1. Cybersecurity With the emergence of social networks and the advancement of technology, it was necessary to create something that would allow the safeguarding of users of social networks, so, in the 80’s, emerged the concept of cybersecurity (Academy, 2021). According to Shea (n.d.), “Cybersecurity is the protection of Internet-connected systems such as hardware, software and data from cyberthreats. The practice is used by individuals and enterprises to protect them against unauthorized access to data centers and other computerized systems”. Cybersecurity consists of a set of technologies, designed to protect networks, data, and systems against cyber-attacks. Some people consider the emergence of cyber-security as the third industrial revolution, where the presence of large-scale information and communication technologies, involved in various areas of human activity, is observed, and has the capacity to reduce the risk of attack and protect against the unauthorized entry of third parties into the systems. 3.2.2. Concepts In order to have a successful cyber-security system, it is necessary to fulfil three great characteristics, known as the Triad CIA (Walkowski, 2019), a concept without whom it would not be possible to implement any kind of cybersecurity. And the three big requirements are: 32 Information related to computer security, cybersecurity, their concepts, treats and cybersecurity in social networks were addressed in section C, using the following questions: • Do you keep the passwords saved in the browser? • Which social network provides the best data security? • Do you trust in cybersecurity? • How well informed do you feel about cybercrime risk? • Do you agree or disagree with the following statements? ▪ I avoid revealing my personal information. ▪ The risk of being a cybercrime victim is increasing. ▪ I’m concerned that my personal information isn’t secure on the websites. ▪ I’m concerned that my personal information isn’t protected the public authorities. ▪ A protection tool, like an antivirus, will protect me from cybercrime? • Cybercrimes include many types of criminal activities. How concerned are you, personally, about experiencing or being a victim of the following situations? ▪ Device infection with malicious software (malware, etc.). ▪ Identity theft (someone that steals your personal information). ▪ Bank card or online banking fraud. ▪ Hacking your social networks or email account. ▪ Online material that promotes racial or religious extremism. ▪ Cyber-attacks that prevent you from accessing online services, such as your bank account. ▪ Payment request in exchange for regaining control over your device. ▪ Online fraud in which purchased products are not delivered, counterfeit or do not correspond to the advertised. • In your opinion, which of these situations represents a very serious, reasonably serious, minor crime or is it not even a crime? ▪ Infection of devices with malicious software (malware, etc.). ▪ Identity theft (someone that steals your personal information). ▪ Bank card or online banking fraud. ▪ Hacking your social networks or email account. ▪ Online material that promotes racial or religious extremism. 33 ▪ Cyber-attacks that prevent you from accessing online services, such as your bank account. ▪ Payment request in exchange for regaining control over your device. ▪ Online fraud in which purchased products are not delivered, counterfeit or do not correspond to the advertised • What would you do in the following situations if you had been a cybercrime victim? ▪ Discover malicious software on your device (virus, etc.). ▪ Identity theft (someone that steals your data). ▪ Being a victim of online bank or bank card fraud. ▪ Find online child pornography. ▪ Hacking your social networks or email account. ▪ Finding online material that promotes racial or religious extremism. ▪ Payment request in exchange for regaining control over your device. ▪ Receive fraudulent e-mails or phone calls asking for your personal information (e.g., login, computer access, fraudulent payments, or your bank information). ▪ Online fraud in which purchased products are not delivered, counterfeit or do not correspond to the advertised. The structured survey is available in the annexes, in order to facilitate the analysis of the questions proposed to the respondents. 34 4.2. SURVEY After the creation of the structured survey, it was made available online, on Facebook, LinkedIn, and email platforms, obtaining a total of 170 final responses. 4.2.1. Part A – Characterization of respondents Of the 170 respondents, 99 (58%) are female and 71 (42%) are male. Graphic 2 – Age of Respondents. We can see that the majority of answers correspond to ages between 26 - 35 (31%), followed by the 36 to 45 age group with 24%. < 25 26 - 35 36 - 45 46 - 55 56 - 65 > 66 Age Group 15% 31% 24% 23% 6% 2% 0% 5% 10% 15% 20% 25% 30% 35% 42% 58% Male Female Graphic 1 – Gender of Respondents. 35 Graphic 3 – Education of Respondents.

In the first section, will be shown the results of the analysis of the second part of the survey related to social media. In the second section will be shown the results of the cybersecurity analysis (Part C). 4.2.2.1. Part B 1. How much time do you spend on social media per day? Graphic 5 – Analisis of Question 1. In graph 5, we can see that 37% of respondents spend between 1 and 2 hours a day on social networks. It should be noted that only 17% of respondents spend more than 3 hours on social networks. 19% 37% 27% 17% 0% 5% 10% 15% 20% 25% 30% 35% 40% Less than 1 hour From 1 hour to 2 hours From 2 hours to 3 hours More than 3 hours 37 2. Which of the following social networks do you use? Graphic 6 – Analysis of Question 2. In the chart above the vast majority of respondents use WhatsApp (18%) and then Facebook, with 17% of responses.

RESEARCH LIMITATIONS The biggest limitation of this research was the data used. the first moment starts with the survey that was sent to the respondents, as it is worrying that some of them may have provided wrong answers or false data. In fact, this is because the survey was online, both on Facebook and LinkedIn and was sent by email, it was a bit long and there was no compensation for respondents. Another limitation was the time restriction. The survey was carried out within a stipulated deadline, however, there were some delays, especially in the delivery of data by respondents. As the survey was online, users were free to fill it at any time or day. There were also other challenges beyond this research, such as balancing work for the master’s degree and my daily work. Therefore, as I was limited in terms of time, I took advantage of all the free time I had to be able to dedicate myself to this research. As there were also monetary constraints, data analysis was not done through premium tools. The main data collection tool to lower research cost. The selected sample was also a limitation, as it was very difficult to find respondents who would make available part of their time to answer the survey. Initially, when the survey was made available on social networks, not all volunteers filled in and sent back their answers. However, even with all these limitations, a significant number of responses were obtained, enough to extract the necessary information from them. And, finally the biggest limitation found in this research was writing. To carry out this research and presenting the problems objectively seems to be an easy thing to do. However, once the information becomes available and new discoveries are made, research development becomes more challenging. 65 5.3. FUTURE WORK By analysing the most diverse works in the existing literature on the subject, this research sought to address the main threats to privacy and security in social media. This has been outlined by earlier researchers in their works. For this reason, this research aims to present some areas for future researchers to deepen and, probably, bring more knowledge on the subject. One of the topics that future researchers will be able to address is to thoroughly research and analyse how applications are collecting all users’ information and how access to personal information can be limited. Another point that can be addressed in future research is how social networks and governments can collaborate together to fight cybercrime, which increases day by day, to avoid bigger problems. A third point that could also be addressed is the legislation that governments are or should be drafting to protect their citizens and how they can ensure their privacy. It would also be interesting to make the survey available by different parts of the world and also by different age groups, in order to gain more knowledge about how people are informed about the exposure of their data on online platforms and how they protect themselves. 66 BIBLIOGRAPHY Aboulhosn, S.
