Single Sign-On (SSO) is a user authentication process that allows a user to access multiple applications with one set of login credentials. SSO is also referred to as reduced sign-on or federated identity management.
Advantages of SSO
- Enhanced Security:
- Ability to use stronger passwords since users only need to remember one.
- Reduces the likelihood of users writing down passwords or using weak passwords.
- Simplified Administration:
- Easier to manage user access and permissions centrally.
- Streamlines the process of adding or removing users from systems.
- Improved User Experience:
- Users spend less time logging into different systems.
- Increases productivity by reducing the time needed to access resources.
Disadvantages of SSO
- Single Point of Failure:
- If the SSO system is compromised, attackers could potentially access all integrated systems and resources.
- Database Vulnerability:
- If the database storing credentials is compromised, all user passwords and access could be exposed.
Thin Client and SSO
- Thin Client:
- A computing approach where the client (user’s computer) does not perform any heavy computing tasks, but rather, accesses services and applications remotely (usually via a server).
- Thin Client as SSO:
- It can be considered a form of SSO because it centralizes the management of user sessions and access to applications, often requiring only one login for multiple services.
SSO systems aim to balance ease of use with security, making them a popular choice in environments where users need to access multiple systems frequently. However, the implementation of robust security measures is crucial to mitigate the risks associated with SSO.
