The TACACS+ protocol provides detailed accounting information and flexible administrative control over the authentication, authorization, and accounting process. ... TACACS+ uses Transmission Control Protocol (TCP) for its transport. TACACS+ provides security by encrypting all traffic between the NAS and the process.

No debate here, TACACS+ is the answer but to those who asked RADIUS = UDP "DIAL-IN" "REMOTE SERVERS" Kerberos = Multi-factor "Client-Server" "Tickets" "UDP and TCP"
