OAuth 2.0 and OpenID Connect in Cybersecurity - Mini Project: Build & Apply

Understanding OAuth 2.0 and OpenID Connect

📖 Scenario: You are learning about how websites and apps let users log in securely using services like Google or Facebook without sharing their passwords directly. This is done using OAuth 2.0 and OpenID Connect protocols.Imagine you want to build a simple explanation of how these protocols work together to allow safe login and access to user information.

🎯 Goal: Build a step-by-step explanation using simple data structures that represent the key parts of OAuth 2.0 and OpenID Connect. This will help you understand the flow and components involved in these protocols.

📋 What You'll Learn

Create a dictionary representing OAuth 2.0 roles and their descriptions

Add a variable for the main OAuth 2.0 grant type used for user login

Create a list of OpenID Connect scopes that request user information

Add a final dictionary combining OAuth 2.0 and OpenID Connect elements to show their relationship

💡 Why This Matters

🌍 Real World

OAuth 2.0 and OpenID Connect are widely used to let users log in to apps securely using accounts from trusted providers like Google, Facebook, or Microsoft without sharing passwords.

💼 Career

Understanding these protocols is essential for cybersecurity professionals, software developers, and IT specialists who build or secure applications that require user authentication and authorization.

1

Create OAuth 2.0 roles dictionary

Create a dictionary called oauth_roles with these exact entries: 'Resource Owner' with value 'User who owns the data', 'Client' with value 'Application requesting access', 'Authorization Server' with value 'Server that grants tokens', and 'Resource Server' with value 'Server hosting the protected data'.

Cybersecurity

# Create the oauth_roles dictionary with specified keys and values
# Your code here

Think of the main players in OAuth 2.0 and write them as keys with simple descriptions as values.

2

Add OAuth 2.0 main grant type

Add a variable called main_grant_type and set it to the string 'Authorization Code', which is the main OAuth 2.0 grant type used for user login.

Cybersecurity

oauth_roles = {
    'Resource Owner': 'User who owns the data',
    'Client': 'Application requesting access',
    'Authorization Server': 'Server that grants tokens',
    'Resource Server': 'Server hosting the protected data'
}
# Add the main_grant_type variable below
# Your code here

Need a hint?

This grant type is the most common way users log in via OAuth 2.0.

3

Create OpenID Connect scopes list

Create a list called oidc_scopes containing these exact strings: 'openid', 'profile', and 'email'. These scopes request user identity information in OpenID Connect.

Cybersecurity

oauth_roles = {
    'Resource Owner': 'User who owns the data',
    'Client': 'Application requesting access',
    'Authorization Server': 'Server that grants tokens',
    'Resource Server': 'Server hosting the protected data'
}

main_grant_type = 'Authorization Code'
# Create the oidc_scopes list with 'openid', 'profile', and 'email'
# Your code here

Need a hint?

These scopes tell the server what user info the app wants to access.

4

Combine OAuth 2.0 and OpenID Connect elements

Create a dictionary called oauth_oidc_summary with two keys: 'OAuth 2.0' set to the oauth_roles dictionary, and 'OpenID Connect' set to the oidc_scopes list. This shows how OAuth 2.0 and OpenID Connect relate.

Cybersecurity

oauth_roles = {
    'Resource Owner': 'User who owns the data',
    'Client': 'Application requesting access',
    'Authorization Server': 'Server that grants tokens',
    'Resource Server': 'Server hosting the protected data'
}

main_grant_type = 'Authorization Code'

oidc_scopes = ['openid', 'profile', 'email']
# Create oauth_oidc_summary dictionary combining oauth_roles and oidc_scopes
# Your code here

Need a hint?

This dictionary shows the connection between OAuth 2.0 roles and OpenID Connect scopes.
