300-445 Question 166
Select 2You are testing a web application for secure authentication methods. The application needs to allow third-party authentication providers, support single sign-on, and integrate with enterprise identity systems while ensuring minimal exposure of user credentials. Which authentication method(s) would be the most appropriate in this scenario?
- A
Basic Authentication
- B
OAuth
- C
SAML
- D
Digest Authentication
- E
Bearer Tokens
Show answer and explanation
Correct answers: B, C
Explanation
OAuth and SAML are the most appropriate options for this scenario. OAuth enables secure, token-based authentication with third-party providers and supports single sign-on, reducing the need to expose user credentials. SAML is designed for enterprise identity systems and also supports single sign-on, making it an excellent choice for enterprise-level web applications requiring secure and efficient authentication. Basic and Digest Authentication do not meet the requirements of this scenario, and while Bearer Tokens are used in OAuth, they are not a standalone authentication method.
- A. Incorrect.
Basic Authentication is not suitable for this scenario because it requires users to provide their credentials directly to the application, which increases the risk of credential compromise. It also lacks support for third-party authentication providers and single sign-on.
- B. Correct.
OAuth is highly appropriate for this scenario because it facilitates third-party authentication providers, supports single sign-on, and minimizes credential exposure by using access tokens instead of sharing user credentials directly.
- C. Correct.
SAML is suitable because it is designed for enterprise identity systems and supports single sign-on. It enables secure communication between identity providers and service providers, making it ideal for a scenario requiring enterprise-grade security.
- D. Incorrect.
Digest Authentication is not suitable for this scenario as it is an outdated method and does not support third-party authentication, single sign-on, or integration with enterprise identity systems.
- E. Incorrect.
Bearer Tokens are often used in conjunction with OAuth but cannot fulfill the requirements independently. They are part of the token-based authentication mechanism rather than a standalone method.
