Which of the following is addressed by Kerberos?
A.
Authorization and authentication.
B.
Validation and integrity.
C.
Confidentiality and integrity.
Explanation:
Kerberos is a network authentication protocol. It is designed to provide strong authentication for
client/server applications by using secret-key cryptography. A free implementation of this protocol is
available from the Massachusetts Institute of Technology. Kerberos is available in many commercial
products as well. Kerberos was created by MIT as a solution to these network security problems. The
Kerberos protocol uses strong cryptography so that a client can prove its identity to a server (and
vice versa) across an insecure network connection. After a client and server has used Kerberos to
prove their identity, they can also encrypt (confidentiality) all of their communications to assure
privacy and data integrity as they go about their business.
