Your company's network uses cisco equipment. You don’t want to have to individually configure the username and password within the configuration of each device. You also want to ensure that all of the information sent for authentication is encrypted. Which protocol should you use?
Terminal Access Controller Access-Control System Plus (TACACS+) is a protocol developed by Cisco to provide remote authentication, authorization and accounting (AAA) services using a centralized server while encrypting the entire packet sent back to the server. RADIUS is a similar protocol used for authentication but it only encrypts the password.
