Explanation
TACACS+ (Terminal Access Controller Access Control System Plus) is specifically designed for granular, per-command authorization, making it ideal for controlling exactly which commands a user can execute on network devices like routers and switches. Unlike RADIUS, which bundles authentication and authorization together, TACACS+ separates all three AAA functions (Authentication, Authorization, Accounting) and encrypts the entire communication payload. TKIP and AES are encryption protocols, not authentication or authorization frameworks.
