1. What is Cross-Site Request Forgery (CSRF) in web security?
- A technique to enhance website aesthetics
- Unauthorized takeover of a user's active session
- A method for securely displaying user preferences on the website
- Forcing a user to perform an unwanted action without their consent
Cross-Site Request Forgery (CSRF) involves forcing a user to perform an unwanted action without their consent.
2. How can CSRF attacks exploit an active user session?
- By improving website aesthetics
- By preventing user authentication
- By tricking the victim into unknowingly submitting a request on a trusted website where they are authenticated
- By displaying user preferences on the website
CSRF attacks exploit an active user session by tricking the victim into unknowingly submitting a request on a trusted website where they are authenticated.
3. What is the primary goal of an attacker in a CSRF attack?
- To improve website aesthetics
- To gain unauthorized access to an active user session
- To encourage secure user interactions
- To perform actions on behalf of the victim without their consent
The primary goal of an attacker in a CSRF attack is to perform actions on behalf of the victim without their consent.
4. How does a CSRF attack differ from a Cross-Site Scripting (XSS) attack?
- CSRF attacks involve injecting malicious scripts into web pages
- XSS attacks force users to perform unwanted actions without their consent
- CSRF attacks trick users into unknowingly submitting requests on trusted websites where they are authenticated
- XSS attacks manipulate the Document Object Model (DOM) to steal session data
CSRF attacks trick users into unknowingly submitting requests on trusted websites where they are authenticated, whereas XSS attacks involve injecting malicious scripts into web pages.
5. What type of actions can CSRF attacks potentially lead to?
- Enhancing website aesthetics
- Improving user experience
- Performing unauthorized actions, such as changing account settings or making financial transactions
- Displaying user preferences on the website
CSRF attacks can potentially lead to performing unauthorized actions, such as changing account settings or making financial transactions.
6. How can anti-CSRF tokens help prevent CSRF attacks?
- By enhancing website aesthetics
- By preventing user authentication
- By including unique tokens in each request that are verified on the server side
- By displaying user preferences on the website
Anti-CSRF tokens help prevent CSRF attacks by including unique tokens in each request that are verified on the server side.
7. What role does the SameSite attribute in cookies play in mitigating CSRF vulnerabilities?
- To improve website aesthetics
- To prevent user authentication

- By enhancing website aesthetics
- By preventing user authentication
- By including additional headers in requests that are checked on the server side to validate the origin
- By displaying user preferences on the website
The use of custom headers can contribute to CSRF prevention by including additional headers in requests that are checked on the server side to validate the origin.
9. Why is it essential to validate and sanitize user inputs in web applications?
- To improve website aesthetics
- To prevent user authentication
- To ensure that user inputs, such as form data, are safe and do not contain malicious content
- To display user preferences on the website
Validating and sanitizing user inputs is essential to ensure that user inputs, such as form data, are safe and do not contain malicious content, thus helping prevent CSRF attacks.
