What is CAS authentication and how does it enhance security?

CAS, or Central Authentication Service, is a single sign-on protocol that allows users to access multiple applications with one set of credentials. It enhances security by reducing password fatigue and minimizing the risk of phishing.

Can you explain how CAS works in a typical scenario?

Sure! In a typical scenario, a user tries to access an application. They are redirected to the CAS server to log in. Once authenticated, the CAS server sends a ticket back to the application, allowing access without needing to log in again.

What are the benefits of using CAS over traditional authentication methods?

The benefits include improved user experience, centralized user management, reduced password-related issues, and enhanced security through fewer login prompts.

Are there any security risks associated with CAS?

Yes, while CAS improves security, risks include potential single points of failure and the need for robust server security to prevent unauthorized access.
