Mastering Active Directory (AD DS) | Part 17 | Kerberos vs NTLM Authentication Explained | Security

Welcome back to the Mastering Active Directory (AD DS) series.

In Part 17, we explore one of the most important Active Directory security topics — Kerberos vs NTLM Authentication.

Authentication is the foundation of Active Directory security, and understanding how Kerberos and NTLM work is essential for system administrators, security engineers, and anyone preparing for Windows Server, Active Directory, or Cybersecurity interviews.

In this video, we will break down the complete authentication process, explain the differences between Kerberos and NTLM, and demonstrate how authentication works in an enterprise Active Directory environment.

This session includes real-world examples, security implications, troubleshooting tips, and interview questions so that you can confidently understand and explain authentication in Windows environments.
