What does TACACS+ stand for?

TACACS+ stands for Terminal Access Controller Access Control System. This protocol is used to provide centralized authentication, authorization, and accounting services for users who access network devices. TACACS+ allows for secure communication between clients and servers by encrypting the entire packet, which enhances security compared to its predecessor, TACACS, which only encrypted the password.

The acronym is specifically important because it highlights the system's original purpose related to terminal access management. By understanding that TACACS+ is focused on access control, network administrators can appreciate its role in managing user privileges and maintaining security within network systems. The other choices do not accurately represent the established definition or function of TACACS+, which is built on the foundational protocols used for centralized access control in enterprise environments.
