encrypted security token that can be used to access a particular service. RADIUS (Remote Authentication Dial-In User Service) is a commonly used authentication method. TACACS+ (Terminal Access Controller Access Control System Plus) is similar to RADIUS but is used with Unix networks. RADIUS employs UDP (User Datagram Protocol) and TACACS+ employs TCP (Transmission Control Protocol.Some specialized authentication servers employ smart cards or biometric verification in addition to one or more of the above
