Kerberos

/ˈkɜrbəˌrɑs/ noun

Definition

A computer network authentication protocol that provides secure communication over non-secure networks. It uses secret-key cryptography and a trusted third party for authenticating client-server applications.

Etymology

Named after Cerberus, the three-headed dog that guards the gates of Hades in Greek mythology. The name was chosen because the protocol has three components that work together to guard network access.

Kelly Says

Kerberos is a perfect example of how ancient mythology influences modern technology naming! The three 'heads' represent the client, server, and authentication server, all working together to keep unauthorized users out of network resources.
