Understanding Cyber Security and Online Safety

Cybersecurity is the practice of protecting systems, networks, programs and devices from digital attacks.

These digital attacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes.

Online safety is the act of maximizing a user’s personal safety and security risks to private information and property associated with using the internet.

It involves understanding the hazards associated with the digital space and developing strategies to avoid them.

Key Vocabulary of Cyber Security

To comprehend texts on digital safety, familiarity with specific terminology is essential. The following terms are frequently encountered in discussions about online security:

1. Phishing: The fraudulent practice of sending emails or messages that appear to be from reputable companies to induce individuals to reveal personal information, such as passwords or credit card numbers.
2. Malware: Malicious software designed to disrupt, damage, or gain unauthorized access to a computer system or mobile device.
3. Digital Footprint: The permanent trail of data, posts, and digital records left behind by an individual while using the internet.
4. Social Engineering: The psychological manipulation of people into performing actions or divulging confidential information.
5. Two-Factor Authentication (2FA): A security process where a user provides two different authentication factors to verify their identity before gaining access to an account.
6. Vulnerability: A weakness in a computer system, security procedure, or internal control that can be exploited by a cyberthreat.

Passage A: The Invisible Threat

In the contemporary digital era, the internet has transformed from a luxury into an indispensable utility. From online banking and virtual classrooms to social media interactions, human lives are increasingly anchored in cyberspace. However, this rapid digitization has also birthed a sophisticated breed of criminals who exploit the vulnerabilities of unsuspecting internet users. In Nigeria, cyber threats have evolved from crude email scams to highly targeted digital operations, making cybersecurity an urgent national and individual priority.

One of the most prevalent methods employed by cybercriminals is social engineering, particularly phishing. Phishing involves the use of deceptive emails, text messages, or websites that mimic legitimate institutions, such as commercial banks, government agencies, or telecommunications companies. The primary objective is to trick the recipient into revealing sensitive personal data, such as Bank Verification Numbers (BVN), passwords, or Personal Identification Numbers (PIN). For instance, an unsuspecting user might receive an urgent SMS claiming that their bank account has been suspended due to a lack of National Identification Number (NIN) linkage. Panic-stricken, the user clicks on the provided link, unknowingly handing over their credentials to fraudsters.

To combat these threats, individuals must cultivate cyber-smart habits. Cybersecurity experts emphasize that legitimate organizations will never request sensitive credentials via SMS or unsecured links. Furthermore, the implementation of multi-factor authentication (MFA) adds an extra layer of defense, ensuring that even if a password is compromised, unauthorized access remains blocked. As the digital landscape continues to expand, vigilance remains the ultimate shield against the invisible adversaries of the virtual world.

Passage B: Guarding the Digital Footprint

The rise of social media platforms has democratized communication, allowing individuals to share their lives, opinions, and achievements with a global audience. However, many users remain oblivious to the permanent nature of their digital footprint. A digital footprint refers to the trail of data that a person leaves behind while browsing the internet, posting on social media, or interacting online. This trail can be harvested by malicious actors, advertisers, and even future employers, often with far-reaching consequences.

On popular platforms, users frequently share real-time locations, school addresses, and personal photographs. While seemingly harmless, this information provides cybercriminals with the raw material needed for identity theft and physical tracking. For example, a cybercriminal can piece together a user’s daily routine simply by analyzing their public posts. This process, known as digital profiling, enables fraudsters to craft highly convincing scams targeted at the user or their family members.

Securing one’s digital footprint requires a deliberate shift in online behavior. Privacy settings on social media platforms should be configured to restrict access to trusted connections only. Additionally, users must exercise critical judgment before sharing any piece of information online. Once data is uploaded to the internet, retrieving it completely becomes virtually impossible. Therefore, online safety is not merely a technical configuration; it is a mindset of continuous caution and digital responsibility.

Comprehension Questions for Passage B

Based on Passage B, answer the following questions:

1. What is a digital footprint according to the writer?
2. Identify three groups of people who can harvest an individual’s digital footprint.
3. How do cybercriminals use public posts to target individuals?
4. What is the writer’s view on the permanence of online data?
5. “…Once data is uploaded to the internet…”
   1. What grammatical name is given to this expression?
   2. What is its function in the sentence?
6. For each of the following words, find another word or phrase which means the same and can replace it as used in the passage:
   1. oblivious
   2. harvested
   3. harmless
   4. deliberate
   5. retrieve

Displaying Cyber-Smartness

Displaying cyber-smartness is a practical skill that involves identifying and avoiding online threats in daily life. Cybercriminals often use urgency, fear, or greed to manipulate their targets. Recognizing these psychological triggers is the first step in maintaining online safety.

Observe the diagram below to understand how a typical phishing message is structured and how to identify its red flags.

To verify the legitimacy of any digital communication, the following steps should be taken:

1. Check the Sender’s Address: Fraudulent emails often use addresses that look similar to official ones but contain subtle misspellings or use public domains like @gmail.com instead of corporate domains.
2. Analyze the Tone: Messages that demand immediate action, threaten account suspension, or offer unexpected financial rewards are highly suspicious.
3. Inspect the Links: Hovering over a link without clicking it reveals the actual destination URL. If the URL does not match the official website of the organization, it should not be clicked.
4. Avoid Sharing Personal Information: Legitimate institutions do not request passwords, PINs, or full card details via email or text message.
