Authentication Protocols and Methods

The video tutorial explains the process of network authentication, focusing on the use of centralized authentication servers. It covers various protocols like RADIUS, TACACS+, and Kerberos, highlighting their features and applications. The tutorial also discusses the importance of multi-factor authentication and provides guidance on choosing the right authentication method based on network requirements.
