CHAPTER 39
Configuring Kerberos
Kerberos is a secret-key network authentication protocol, developed at the Massachusetts Institute of
Technology (MIT), that uses the Data Encryption Standard (DES) cryptographic algorithm for encryption
and authentication. Kerberos was designed to authenticate requests for network resources. Kerberos, like
other secret-key systems, is based on the concept of a trusted third party that performs secure verification of
users and services. In the Kerberos protocol, this trusted third party is called the key distribution center
(KDC).
