Introduction
The term Kerberos was derived from the Greek mythology. Cerberus is
the latin variant of Kerberos, who guarded the entrance of Hades, the
Greek hell. The Kerberos security system, on the other hand, guards
electronic transmissions that are sent across a network.
Kerberos is a mature network authentication protocol based on the RFC
1510 (The Kerberos Network Authentication Service (V5)) specification of
the Internet Engineering Task Force (IETF). It is designed to provide
strong authentication for client or server applications using the shared
secret key cryptography.
The Kerberos server is based on a distributed client/server architecture.
It ensures secure communication in a networked environment by
leveraging individual trust relationships. It then brokers that trust
across enterprise wide, distributed client/server networks.
