AAA Components • AAA server • Authenticates users accessing a device or network • Authorizes user to perform specific activities • Performs accounting of device or user activities • Network Access Server (NAS) or Access Device • A router, switch, or other network device that can perform AAA functions on users or devices connecting to it • RADIUS or TACACS+ • Protocols that can be used by an access device to communicate with the AAA server
AAA Network Components Note: AAA server may communicate with a Windows domain controller or a Unix server that has the user password database
