An organization wants to utilize a common, Internet-based third-party provider for authorization and authentication.
The provider uses a technology based on OAuth 2.0 to provide required services.
To which of the following technologies is the provider referring?
Click on the arrows to vote for the correct answer
A. B. C. D.A.
The third-party provider mentioned in the question uses OAuth 2.0 technology for providing authentication and authorization services.
OAuth 2.0 is a widely adopted authorization framework that enables a user to grant limited access to their resources on one site, to another site, without sharing their credentials. It works by providing access tokens that allow the third-party provider to access resources on behalf of the user. This technology is commonly used by social media platforms to allow users to grant access to their profiles without providing their login credentials to other apps.
Now, let's look at the answer options and their respective technologies:
A. Open ID Connect: It is an authentication layer built on top of OAuth 2.0 protocol, which provides identity verification services. It allows users to authenticate across multiple domains without having to remember different usernames and passwords. However, in this case, the provider is referring to the OAuth 2.0 protocol, not Open ID Connect.
B. SAML (Security Assertion Markup Language): It is an XML-based standard used for exchanging authentication and authorization data between parties, particularly between an identity provider and a service provider. SAML provides a framework for exchanging security-related information, but it is not based on OAuth 2.0.
C. XACML (eXtensible Access Control Markup Language): It is a standard for access control policies, which defines a language for expressing policies and a protocol for evaluating them. It enables fine-grained access control policies that are more flexible than traditional access control mechanisms, but it is not related to OAuth 2.0.
D. LDAP (Lightweight Directory Access Protocol): It is a protocol used for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. LDAP is commonly used for authentication, but it is not related to OAuth 2.0.
Therefore, the correct answer is A. Open ID Connect is not the technology that the provider is referring to, but rather OAuth 2.0.
