What is Kerberos Authentication?

Kerberos is a network authentication protocol that uses secret-key cryptography to provide strong authentication for client/server applications. It works by assigning a unique key, called a ticket, to each user who logs on to the network. This ticket is then used to verify the user's identity for each service they access, without requiring the user to re-enter their password. It is commonly used in enterprise environments to securely manage user access to resources and services.
