Fundamentals of Secure Software - OpenID and OpenID Connect

The video tutorial explains Open ID, a decentralized authentication protocol that allows users to log into multiple websites using a single identity. It covers the Open ID process, where users authenticate with an identity provider, which then confirms their identity to other websites. The tutorial also introduces Open ID Connect, an identity layer on top of Oauth 2.0, and explains its flow, including the exchange of authentication codes and access tokens. The video highlights the benefits of using Open ID and Open ID Connect for secure and efficient user authentication across various platforms.

What is the primary benefit of using Open ID for authentication?

• It centralizes user data storage on a single server.

• It allows users to create multiple passwords for different websites.

• It requires webmasters to develop their own login systems.

• It enables users to authenticate across multiple sites with one identity.

In the Open ID protocol, who confirms the user's identity to the website?

• The relying party

• The identity provider

• The end user

• The webmaster

What is a common example of a relying party in the Open ID process?

• A user's personal computer

• A social media platform like Facebook

• A mobile application

• A local network server

How does Open ID Connect enhance OAuth 2.0?

• By providing a new encryption method

• By simplifying the login process

• By adding an authorization layer

• By introducing an identity layer

What is the role of the Open ID Connect provider in the authentication process?

• To redirect users to the relying party

• To send an authentication code to the client

• To store user passwords

• To manage user sessions

Which of the following is NOT a feature of Open ID Connect?

• Discovery of Open ID providers

• Session management

• Encryption of identity data

• Centralized password storage

What is the relationship between OAuth and XACML?

• OAuth is a subset of XACML.

• OAuth and XACML are unrelated standards.

• OAuth handles ownership and consent, while XACML defines authorization policies.

• OAuth is used for authorization policies, while XACML is for authentication.
