TACACS+ TACACS+ provides centralized security for validation of users accessing the switch. TACACS+ provides a centralized user management system, while still retaining consistency with RADIUS and other authentication processes. RADIUS Client RADIUS is a client/server-based protocol in which the server maintains a user database that contains user authentication information, such as user name, password, and accounting information. SSH/SSL Secure Shell (SSH) is a protocol that provides a secure, remote connection to a device. This connection provides functionality that is similar to an inbound telnet connection. Secure Sockets Layer (SSL) protocol provides a means of abstracting an encrypted connection between two stations. Once established, such a connection is virtually no different to use than an unsecured connection.
