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

In this lesson, we’ll see how we can create keytabs and use kadmin to make KDC database changes. The detailed commands to execute and the terminal to execute them appear below, followed by a discussion of the exercise.

This lesson demonstrates creating keytabs and using the kadmin utility.
