DL Cybersecurity and Online Safety 1 — Questions and Answers
Question 1: Which of the following is a strong password example?
- password123
- 12345678
- Th!s1sAStr0ngP@ssw0rd (Correct answer)
- mydogname
Correct answer: Th!s1sAStr0ngP@ssw0rd
A strong password incorporates a variety of character types, including uppercase letters, lowercase letters, numbers, and special symbols. It also needs to be sufficiently long to resist brute-force attacks. 'Th!s1sAStr0ngP@ssw0rd' meets these criteria, making it significantly more secure than simple, common, or easily guessable options like 'password123' or 'mydogname'.
Question 2: What is the main purpose of two-factor authentication (2FA)?
- To back up your data automatically
- To allow logging in from multiple devices simultaneously
- To add an extra layer of security to your account (Correct answer)
- To remember your password for you
Correct answer: To add an extra layer of security to your account
Two-factor authentication (2FA) significantly enhances account security by requiring two distinct forms of verification before granting access. This typically involves something you know (like a password) and something you have (like a code sent to your phone or generated by an app). This extra layer ensures that even if a password is compromised, an unauthorized user cannot access the account without the second factor.
Question 3: Which of the following is an example of phishing?
- Receiving an email from your bank with a security code you requested
- Getting an email with a link asking you to verify your account but coming from an unknown sender (Correct answer)
- Installing antivirus software on your device
- Receiving a newsletter you subscribed to
Correct answer: Getting an email with a link asking you to verify your account but coming from an unknown sender
Phishing is a deceptive cyberattack where criminals attempt to trick individuals into revealing sensitive information by impersonating a trustworthy entity. An email from an unknown sender asking you to click a link to 'verify' your account is a classic phishing tactic designed to steal login credentials or install malware. Legitimate organizations typically do not request account verification via unsolicited emails with embedded links.
Question 4: What should you do if you accidentally click on a suspicious link in an email?
- Ignore it and continue working
- Share the link with others to see if it’s dangerous
- Disconnect from the internet, scan your device with antivirus software, and change your passwords if needed (Correct answer)
- Call the sender immediately
Correct answer: Disconnect from the internet, scan your device with antivirus software, and change your passwords if needed
If you accidentally click a suspicious link, immediate action is crucial to mitigate potential damage. Disconnecting from the internet prevents further data transmission or malware downloads. Scanning your device with antivirus software helps detect and remove any threats, and changing passwords for accounts that might have been compromised protects your personal information.
Question 5: Which of these is the safest way to access a public Wi-Fi network?
- Connect without any precautions
- Use a VPN (Virtual Private Network) (Correct answer)
- Access only social media sites
- Save your passwords while browsing
Correct answer: Use a VPN (Virtual Private Network)
Public Wi-Fi networks are often unsecured, making your data vulnerable to interception by malicious actors. Using a Virtual Private Network (VPN) encrypts your internet connection, creating a secure tunnel for your data. This protects your online activities and sensitive information from potential eavesdroppers on the same public network.
