Question

Quizplus · Accepted Answer

A ticket in Kerberos is a temporary set of credentials issued by the Kerberos authentication server to a user after it has authenticated the user's identity. The user then presents this ticket to other servers to prove its identity and gain access to the protected services.

Answer: A is incorrect because a Kerberos client or user is known as a principal.

Answer: B is incorrect because a key is used for encryption and decryption of messages exchanged between the Kerberos authentication server and the client, but not for gaining access to services.

Answer: D is incorrect because auditing and unauthorized access are not related to the purpose of a ticket in Kerberos.
