300-445 Question 164
Select 3You are designing a network assurance solution for a web application that requires secure authentication and supports integration with third-party identity providers. The application must allow users to log in using their corporate credentials with minimal user interaction while ensuring token-based access to APIs. Which authentication methods should you implement?
- A
OAuth
- B
SAML
- C
Basic Authentication
- D
Bearer Tokens
- E
Digest Authentication
Show answer and explanation
Correct answers: A, B, D
Explanation
To meet the requirements of secure authentication, third-party identity provider integration, and token-based API access, implementing OAuth and SAML is essential. OAuth provides a framework for secure token-based access, while SAML facilitates Single Sign-On (SSO) and corporate credential integration. Bearer Tokens complement OAuth by providing a mechanism for secure token-based access. Basic and Digest Authentication are outdated and do not meet modern security or integration requirements.
- A. Correct.
OAuth is a widely used framework for token-based authentication and is suitable for enabling secure API access. It also supports integration with third-party identity providers.
- B. Correct.
SAML (Security Assertion Markup Language) is ideal for enabling Single Sign-On (SSO) and supports integration with corporate identity providers, allowing users to log in using their corporate credentials.
- C. Incorrect.
Basic Authentication involves sending usernames and passwords directly in each request, making it less secure for modern applications. It does not meet the requirements for secure token-based authentication or SSO.
- D. Correct.
Bearer Tokens are used in conjunction with OAuth to enable secure token-based access to APIs, which aligns with the requirement for token-based authentication.
- E. Incorrect.
Digest Authentication is an improvement over Basic Authentication but is still outdated and does not provide the flexibility or security required for integrating with third-party identity providers or enabling SSO.
