CompTIA Security+ Certification SY0-601: The Total Course - Network Authentication

The video tutorial covers various network authentication protocols, including legacy protocols like PAP, which are insecure due to cleartext transmission. It explains the Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) and its secure hashing mechanism. The tutorial also discusses NTLM and its use in workgroup computers, as well as Kerberos for Active Directory environments. Additionally, it covers the Extensible Authentication Protocol (EAP) and IEEE 802.1X for network access control, highlighting the role of RADIUS servers in centralized authentication.
