Kerberos is an essential part of any tech stack. It helps mitigate cyber attacks by providing strong authentication for client/server applications by using secret-key cryptography.

In this course, you will cover the basics of network security including: authentication, authorization, and auditing. You will also learn the fundamental concepts of Kerberos such as Key Distribution Center (KDC), Principals, and Ticketing.

Towards the end of this course, you will explore common attacks that are specific to the protocol and how Kerberos works to triage them. Lastly, you will get some hands-on practice with Kerberos where you’ll work to create a principal and request a Ticket-Granting Ticket from an Authentication Server.

By the time you’re done, you will have picked up a new in-demand skill that will allow you to better protect your data.

Kerberos for Beginners: Intro to Network Authentication Protocol

The Kerberos ecosystem consists of various components that come together to implement the authentication protocol in an insecure network. In this lesson, we'll examine the various parts of the puzzle before we delve into their interactions with each other. The important Kerberos components are:

- Realm
- Principal
- Key Distribution Center
- Key
- Ticket

We'll discuss each one of them in turn.


This lesson covers the various actors and entities that participate in the Kerberos protocol.
