![Blurred answer](/static/compass_v2/solution-images/blurred-answer.jpg)
- Do several methods of authentication have any negative effects? What precisely does it do to assist protect compromised accounts from being attacked again?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?Why is hashing passwords rather than encrypting password files preferable?
- Many flaws exist in password authentication methods. What are the three vulnerabilities, and what is the common mitigation for each of them?What exactly are the aims of authentication? Different authentication techniques have various strengths and limitations.Does using several authentication methods at once have any drawbacks? Is there a way in which it helps to ensure that compromised accounts remain secure?
- 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?The process of using two or more different authentication methods is referred to as "multi-factor authentication," and it is known by that name. How often do hackers succeed in gaining access to an account that has been stolen?Explain why challenge-response authentication is necessary. Password-based methods are more susceptible.
