AAA, RADIUS and TACACS+

Using the local database of a router to store usernames and passwords is fine in a small network, but when there are hundreds of network routers and switches, and several administrators, keeping all of that information on each router is tedious. What can be done? The answer is "centralized" AAA services delivered via Remote Authentication Dial-In User Service (RADIUS) and/or Terminal Access Controller Access Control System (TACACS+). Have no fear, in this video Keith walks you through these concepts and then demonstrates them for reinforcement.

Maps to CCNA Security objectives: Implement security on Cisco routers; Describe securing the management plane; Implement AAA (authentication, authorization, and accounting); Describe TACACS+; Describe RADIUS; Describe AAA; Verify AAA functionality; Describe secure network management; Implement secure network management.
