CCNA Security - RADIUS and TACACS+

1. TACACS+ uses TCP and RADIUS uses UDP.
2. TACACS+ encrypts the entire body of the packet and RADIUS encrypts only the password.
3. TACACS+ uses the AAA technology by separating authentication, authorization and accounting, on the other hand, RADIUS  combines authentication and authorization.
4. TACACS+ supports AppleTalk, NetBIOS and IPX
5. TACACS+ uses multiple challenge response for each of the AAA processes. RADIUS uses only one challenge response.
