Cross-Site Request Forgery Overview

  1. What is Cross-Site Request Forgery (CSRF)?

    • A) A type of attack that involves manipulating user input fields
    • B) An attack that tricks a user into sending a malicious request to a target website
    • C) A method for accessing encrypted data
    • D) An attack that involves exploiting vulnerabilities in network protocols

  2. What types of requests can be involved in a CSRF attack?

    • A) GET and POST requests
    • B) PUT and DELETE requests
    • C) PATCH and OPTIONS requests
    • D) HEAD and TRACE requests

Examples of CSRF Attacks

  1. What can a CSRF attack potentially use a POST request for?

    • A) To access encrypted messages
    • B) To transfer funds or make purchases using sensitive data
    • C) To scan for vulnerabilities in a network
    • D) To send spam emails

  2. What is a potential use of a GET request in a CSRF attack?

    • A) To update a user’s email address
    • B) To execute a command such as deleting all users
    • C) To encrypt sensitive data
    • D) To generate an API key

Impact of CSRF Attacks

  1. What might be the impact of a CSRF attack on an average user?

    • A) The user’s account credentials are encrypted
    • B) The user’s funds are transferred or purchases are made without their knowledge
    • C) The user’s network connection is disrupted
    • D) The user’s data is backed up automatically

  2. What can a successful CSRF attack on a high-privilege user lead to?

    • A) Data encryption
    • B) Full system compromise
    • C) Network speed optimization
    • D) Automated email responses

CSRF vs. XSS

  1. How do CSRF and XSS attacks differ?

    • A) CSRF requires user authentication, while XSS does not
    • B) XSS is used to exploit network protocols, while CSRF does not
    • C) XSS involves email phishing, while CSRF does not
    • D) CSRF is a “two-way” attack, while XSS is a “one-way” attack

  2. What is a defining characteristic of XSS compared to CSRF?

    • A) XSS requires user authentication and involves sending requests
    • B) XSS does not require authentication but involves executing scripts within the user’s browser
    • C) XSS is used to encrypt data, while CSRF does not
    • D) XSS only targets server-side vulnerabilities, while CSRF targets client-side vulnerabilities

Mitigating CSRF

  1. Which of the following is a recommended practice for protecting against CSRF attacks?

    • A) Use CAPTCHA to prevent automated requests
    • B) Encrypt all data before transmission
    • C) Increase the session timeout period
    • D) Disable all external API access

  2. What role do anti-CSRF tokens play in mitigating CSRF attacks?

    • A) They encrypt user data
    • B) They validate requests to ensure they are legitimate
    • C) They enhance the network speed
    • D) They prevent unauthorized access to network resources

  3. Why is using HTTPS important in preventing CSRF attacks?

    • A) It improves the speed of request handling
    • B) It prevents attackers from intercepting requests
    • C) It provides encryption for sensitive data
    • D) It prevents the use of weak passwords

  4. What is one way to protect against CSRF attacks related to user sessions?

    • A) Set a maximum lifetime for sessions
    • B) Use public Wi-Fi for accessing the application
    • C) Disable all user accounts
    • D) Use only GET requests for sensitive actions

  5. What is the benefit of enforcing strong passwords and two-factor authentication?

    • A) It reduces the risk of unauthorized access and strengthens user authentication
    • B) It speeds up the login process
    • C) It prevents encrypted data from being accessed
    • D) It ensures users always use HTTPS
