What type of systems do Kerberos, KryptoKnight, and SESAME represent?

Kerberos, KryptoKnight, and SESAME are all examples of Single Sign-On (SSO) systems. These systems are designed to allow users to authenticate once and gain access to multiple services or applications without needing to log in separately to each one.

The primary advantage of SSO systems is their ability to enhance user convenience by reducing the number of times a user has to enter their credentials while maintaining secure access to various resources. This functionality is particularly beneficial in enterprise environments where numerous applications are frequently accessed.

In addition to improving user experience, SSO solutions help centralize authentication and can streamline the administration of security credentials, making it easier for organizations to enforce security policies and manage user identities.
