Explain the purpose of a "multifactor authentication" system. What degree of security does it provide in terms of guarding against password theft?
Step by step
Solved in 2 steps
- Explain the concept behind an authentication method that relies on a question and response (CRAS). Why is this method safer than using a password, exactly?An authentication system that uses challenges and responses should be described in detail. What makes it more safe than a system that relies on passwords?Explain the concept of a challenge–response authentication system. What makes it more safe than a normal password-based approach is that
- Explain what the term "authentication challenge-response system" means and why it is more secure than other systems that rely on passwords.Explain how an authentication system that relies on a challenge and a response works. It is not immediately obvious how this new technique offers a higher level of security compared to the standard approach of using passwords.Explain a challenge–response authentication system. It's unclear how this strategy is safer than passwords.
- Explain the practical use of a challenge-response authentication system.How does it make a system that needs a password to access it any less secure?Many flaws exist in password authentication methods. What are the three vulnerabilities, and what is the common mitigation for each of them?An authentication challenge–response system may be described. Why is this approach more secure than a password-based method?
- There are several security flaws in password authentication methods. A common mitigation may be found for each of these vulnerabilities.Distinguish between the benefits and drawbacks of various authentication techniques when it comes to security.Authentication using several factors defies my little knowledge of the subject. In what ways does it help to keep passwords safe, and how does it do this?
