Explanation:
“The Key Distribution Center (KDC) is the most import component within a Kerberos
environment. The KDC holds all users’ and services’ cryptographic keys. It provides authentication
services, as well as key distribution functionality. The clients and services trust the integrity of the
KDC, and this trust is the foundation of Kerberos security.” Pg. 148 Shon Harris CISSP All-In-One
Certification Exam Guide
‘The basic principles of Kerberos operation are as follows:
1.)The KDC knows the secret keys of all clients and servers on the network.
2.)The KDC initially exchanges information with the client and server by using these secret keys.
3.)Kerberos authenticates a client to a requested service on a server through TGS, and by using
temporary symmetric session keys for communications between the client and KDC, the server
and the KDC, and the client and server.
4.)Communication then takes place between the client and the server using those temporary
session keys.”
