CSCU - Certified Secure Computer User Safe Internet Browsing Questions and Answers

Question 1

When you visit a website, it stores a small text file on your computer to remember your preferences, login status, and items in your shopping cart. What is this file called, and what is a primary security risk associated with it?

Accepted Answer

Cookie; it can be hijacked to impersonate you and gain unauthorized access to your accounts.

Answer

This file is a cookie. While cookies are essential for a personalized web experience, they can pose a security risk. If a session cookie is stolen (hijacked), an attacker can use it to impersonate a legitimate user and gain unauthorized access to their accounts and personal information without needing a password.

Question 2

A user wants to research a sensitive topic on a shared family computer without saving the browsing history, search queries, or cookies on the device itself. Which browser feature should they use, and what is a key limitation of this feature?

Accepted Answer

Private Browsing (or Incognito Mode); it does not hide your IP address from your ISP or the websites you visit.

Answer

Private Browsing (or Incognito Mode) creates a temporary session that does not save browsing history, cookies, or form data on the local device. However, it is not truly anonymous. Your Internet Service Provider (ISP), school, or employer can still see your online activity, and the websites you visit can still identify your IP address.

Question 3

Which of the following is the MOST critical visual indicator that a website encrypts the data transmitted between your browser and the server, protecting it from eavesdroppers?

Accepted Answer

The presence of 'https://' and a padlock icon in the browser's address bar.

Answer

The 'https://' in the URL and the corresponding padlock icon are the standard indicators that a website is using HTTPS (Hypertext Transfer Protocol Secure). This protocol encrypts the data in transit, making it unreadable to anyone who might intercept it, which is crucial for protecting sensitive information like passwords and credit card numbers.

Question 4

A user is considering installing a new browser extension that offers to organize their tabs. During installation, it requests permission to 'Read and change all your data on the websites you visit.' Why should this be a cause for concern?

Accepted Answer

This permission level is excessive and could be abused to steal login credentials, monitor activity, or inject malicious scripts.

Answer

Requesting excessive permissions is a major security red flag for browser extensions. An extension with the ability to read and change all data on websites can potentially capture sensitive information like passwords and financial details, track all browsing activity, or inject malicious code into legitimate websites without the user's knowledge.

Question 5

You receive an email with a link to what appears to be your bank's website. Which of the following is the BEST technique to verify the link's legitimacy before clicking?

Accepted Answer

Checking if the email contains the bank's official logo.

Answer

Phishing attacks often use hyperlinks where the displayed text looks legitimate, but the underlying URL points to a malicious site. By hovering the mouse over the link without clicking, you can preview the actual destination URL in the bottom corner of the browser window. This allows you to check for misspellings or entirely different domains before navigating to a potentially dangerous site.
