Fundamentals of Secure Software - OAuth

The video tutorial provides an in-depth explanation of OAuth, an open standard for access delegation. It covers how OAuth allows users to grant websites or applications access to their information without sharing passwords. The tutorial explains the OAuth flow, including the roles of resource owner, resource server, client, and authorization server. It discusses scopes, which define permissions requested by applications, and the use of access and refresh tokens for secure API access. An example of an OAuth request using Gmail's API is also provided, illustrating the process of obtaining authorization codes and tokens.

What is the primary purpose of OAuth?

In the OAuth flow, who is the resource owner?

• The individual owning the data

• The API storing the data

• The application requesting access

• The server issuing tokens

What is the role of the authorization server in OAuth?

• To encrypt data

• To manage user accounts

• To issue access tokens to clients

• To store user data

What is a characteristic of access tokens in OAuth?

• They are issued by the resource server

• They are short-lived and cannot be revoked

• They are long-lived and can last for years

• They are used to store user passwords

How can a refresh token be used in OAuth?

• To manage user accounts

• To store user passwords

• To obtain new access tokens

• To encrypt user data

What is the purpose of the 'state' parameter in OAuth?

• To store user data

• To ensure the request is not forged

• To encrypt the access token

• To manage user accounts
