Broken Authentication Quiz: Test Your Cybersecurity Knowledge

📚 Quick Study Guide

🔑 Broken Authentication: Occurs when an attacker compromises or bypasses authentication mechanisms, gaining unauthorized access. 🛡️ Common Vulnerabilities: Weak passwords, credential stuffing, session fixation, predictable URLs, and insecure password recovery. ⚙️ Impact: Account takeover, data breach, financial loss, and reputational damage. 💡 Prevention Techniques: Multi-factor authentication (MFA), strong password policies, rate limiting, account lockout, regular security audits. 🔐 MFA (Multi-Factor Authentication): Requires users to provide two or more verification factors to gain access. 🔒 Rate Limiting: Limits the number of login attempts from a single IP address within a specific time frame. 🔑 Password Complexity: Enforce strong password policies, including minimum length, character types, and regular password updates.

Practice Quiz

1. Which of the following is a common symptom of broken authentication?

   2. B) Unauthorized access to user accounts.
   3. C) The website displays a CAPTCHA on every page.
   4. D) The server experiences frequent downtime.
2. What is multi-factor authentication (MFA)?
   1. A) A single password that changes regularly.
   2. B) Requiring multiple usernames for a single account.
   3. C) Using two or more verification factors to authenticate.
   4. D) Storing passwords in plain text.
3. What is credential stuffing?
   1. A) Filling out forms with random data.
   2. B) Using stolen usernames and passwords to attempt logins on multiple sites.
   3. C) Encrypting passwords using strong algorithms.
   4. D) Forcing users to create very long passwords.
4. Which of the following is a prevention technique against broken authentication?
   1. A) Disabling password recovery features.
   2. B) Using default passwords for all accounts.
   3. C) Implementing rate limiting on login attempts.
   4. D) Storing passwords in plain text in the database.
5. What is session fixation?
   1. A) A technique to keep user sessions active indefinitely.
   2. B) Forcing users to log out after a short period of inactivity.
   3. C) When an attacker is able to hijack a user session by injecting a known session ID.
   4. D) Using strong encryption for session cookies.
6. Why is it important to enforce strong password policies?
   1. A) To make passwords easier to remember.
   2. B) To reduce the risk of password cracking and unauthorized access.
   3. C) To encourage users to share passwords with each other.
   4. D) To simplify the password recovery process.
7. What is the primary goal of rate limiting on login attempts?
   1. A) To slow down legitimate users.
   2. B) To prevent brute-force attacks by limiting the number of attempts.
   3. C) To make it easier for attackers to guess passwords.
   4. D) To increase server load and cause denial-of-service.
