Which if the following is NOT one of the three components of a federated identity system transaction?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
A federated identity system transaction involves three main components: the user, the identity provider (IdP), and the relying party (RP). The user is the entity seeking access to a resource or service, the identity provider is the entity responsible for authenticating the user, and the relying party is the entity that grants access to the resource or service based on the user's authentication.
A proxy relay is not one of the three components of a federated identity system transaction. A proxy relay is a network component that acts as an intermediary between two or more network endpoints, often used to forward requests from one network to another.
In a federated identity system transaction, the user authenticates with their identity provider, which issues a security token that includes the user's identity information. The user then presents this token to the relying party, which validates the token and grants access to the requested resource or service.
Therefore, the answer to the question is D. Proxy relay.
