Explanation
Kerberos is the authentication protocol that uses a ticket-based system. When a user authenticates to the Key Distribution Center (KDC), they receive a Ticket Granting Ticket (TGT). This TGT is then presented to the Ticket Granting Service (TGS) to obtain service tickets for individual network resources (file servers, applications, etc.) without requiring the user to re-enter their credentials each time. RADIUS is an AAA protocol that uses a challenge/response model, not tickets. Multi-factor authentication is a broader concept about verifying identity using multiple factors. TACACS+ is a Cisco-proprietary AAA protocol that separates authentication, authorization, and accounting but does not use tickets.
