Currently James’s company is using RADIUS for AAA services to connect wireless users to the Windows Active Directory domain. However, the company wants to upgrade to a Cisco-based wireless network and would like to upgrade the older RADIUS. What will James recommend as an upgrade to RADIUS?

Terminal Access Controller Access Control System (TACACS+)

Explanation:

Terminal Access Controller Access Control System (TACACS+) can be used as an upgrade to RADIUS (Remote Authentication Dial-in User Service) for AAA (Authentication Authorization Accounting) services to connect wireless users to the Windows Active Directory domain.

TACACS+ is a Cisco-based wireless network that uses Transmission Control Protocol (TCP) and provides separate authentication, authorization and accounting services for users in bigger networks.

TACACS+ uses TCP port 49 while RADIUS uses UDP port 1812 and 1813.
