Single Sign-On (SSO) in Cybersecurity - Mini Project: Build & Apply

Understanding Single Sign-On (SSO)

📖 Scenario: You work in a company that uses many different web applications for daily tasks. Logging into each app separately is slow and frustrating. Your team wants to understand how Single Sign-On (SSO) can help users log in once and access all apps securely.

🎯 Goal: Build a simple conceptual model of Single Sign-On (SSO) using a dictionary to represent users and their login status, then simulate the SSO process step-by-step.

📋 What You'll Learn

Create a dictionary of users with their login status

Add a variable to represent the SSO login token

Write code to update login status using the SSO token

Complete the model by showing all users logged in after SSO

💡 Why This Matters

🌍 Real World

SSO is widely used in companies and online services to improve user experience by reducing repeated logins.

💼 Career

Understanding SSO helps cybersecurity professionals design secure and user-friendly authentication systems.

1

Create the users dictionary

Create a dictionary called users with these exact entries: 'Alice': False, 'Bob': False, 'Charlie': False. This dictionary shows if each user is logged in (false means not logged in).

Cybersecurity

# Create the users dictionary with login status
# Your code here

Need a hint?

Use curly braces {} to create a dictionary. Each user name is a key, and their login status is the value.

2

Add the SSO token variable

Add a variable called sso_token and set it to True. This token represents that the user has successfully logged in once using SSO.

Cybersecurity

users = {'Alice': False, 'Bob': False, 'Charlie': False}
# Add the SSO token variable
# Your code here

Need a hint?

Just create a variable and assign it the value True.

3

Update users login status using SSO token

Use a for loop with variables user and status to iterate over users.items(). Inside the loop, update each user's login status to the value of sso_token.

Cybersecurity

users = {'Alice': False, 'Bob': False, 'Charlie': False}
sso_token = True
# Update each user's login status using the SSO token
# Your code here

Need a hint?

Use a for loop to go through each user and set their status to True using the sso_token variable.

4

Complete the SSO model

Add a final line that creates a variable called all_logged_in and sets it to all(users.values()). This checks if all users are logged in after SSO.

Cybersecurity

users = {'Alice': False, 'Bob': False, 'Charlie': False}
sso_token = True
for user, status in users.items():
    users[user] = sso_token
# Check if all users are logged in
# Your code here

Need a hint?

Use the all() function to check if every value in the users dictionary is True.
