Kerberos Authentication

Kerberos is an authentication protocol that uses secret-key cryptography to secure client-server communications.

Its use of strong encryption helps prevent network eavesdropping over unsecured networks.

How Kerberos Works

The three main components of Kerberos include:

  1. Client
  2. Server
  3. Key Distribution Center (KDC)

The Kerberos authentication process consists of eight steps, across three different stages:

Stage 1: Client Authentication

Stage 2: Client Service Authorization

Stage 3: Client Service Request
