Kerberos is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Kerberos uses UDP port 88 by default

At least two implementations are available, [Heimdal]( https://www.h5l.org/) and (MIT)(https://web.mit.edu/kerberos/).

OpenSSH implements Kerberos support since early versions.

A Kerberos realm is the domain over which a Kerberos authentication server has the authority to authenticate a user, host or service. A realm name is often, but not always the upper case version of the name of the DNS domain over which it presides.

Configuration files[edit]

Commands[edit]

Activities[edit]

  1. Install Kerberos KDC Server and Client in Linux: apt install krb5-kdc krb5-admin-server krb5-config -y[2]
  2. Understand why time synchronization and DNS plays an important role in order to work KDC properly[3]
  3. Read about SPNEGO
