Single Sign-On (SSO) in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Single Sign-On (SSO)?

Single Sign-On (SSO) is a user authentication process that allows a person to access multiple applications or systems with one set of login credentials, like a single username and password.

beginner

How does SSO improve user experience?

SSO improves user experience by letting users log in once and access many services without needing to enter their password again, saving time and reducing frustration.

intermediate

Name a common protocol used in SSO systems.

A common protocol used in SSO systems is SAML (Security Assertion Markup Language), which helps securely exchange authentication data between parties.

intermediate

What is a potential security risk of SSO?

If an attacker gets access to the single set of login credentials, they can access all connected systems, making it very important to protect the SSO credentials carefully.

beginner

Give an example of a real-life analogy for SSO.

SSO is like having one key that opens many doors in a building, so you don’t need a separate key for each door.

What does Single Sign-On (SSO) allow a user to do?

A Log in once to access multiple applications

B Use multiple passwords for one application

C Sign in anonymously to websites

D Create multiple user accounts automatically

SSO lets users log in once and access many applications without needing to log in again.

Which protocol is commonly used for SSO authentication?

A HTTP

B SMTP

C FTP

D SAML

SAML is a standard protocol used to exchange authentication information in SSO.

What is a key benefit of using SSO?

A Faster access to multiple services

B More passwords to remember

C Increased need for manual logins

D Separate accounts for each service

SSO speeds up access by requiring only one login for many services.

What is a major security concern with SSO?

A It requires multiple passwords

B Users forget their passwords more often

C One compromised password can give access to many systems

D It slows down login processes

If the single password is stolen, attackers can access all connected systems.

Which of these is NOT a feature of SSO?

A Single login for multiple apps

B Multiple passwords for each app

C Improved user convenience

D Centralized authentication

SSO uses one password, not multiple passwords for each app.

Explain how Single Sign-On (SSO) works and why it is useful.

Think about logging in once and accessing many services without repeated passwords.

Describe a security risk associated with SSO and how it can be mitigated.

Consider what happens if someone steals your single login details.
