What AAA protocol(s) encrypts only the password portion of the access request packet between the client and server?
None of these
TACACS+ only
RADIUS only
RADIUS and TACACS+
Terminal Access Controller Access-Control System Plus (TACACS+) is a Cisco-proprietary AAA protocol that uses TCP port 49 and separates the AAA functionalities. Unlike RADIUS, TACACS+ encrypts the entire body of the packet except the TACACS+ header and offers multiprotocol support.
Remote Authentication Dial-In User Service (RADIUS) is an open standard client/server access control protocol which uses UDP. It combines the authentication and authorization functionalities of AAA. RADIUS encrypts only the password of an access request packet between the client and server.
