TACACS+ - Terminal Access Controller Access Control System

Terminal Access Controller Access-Control System Plus (TACACS+) is a security protocol commonly used for providing centralized authentication, authorization, and accounting (AAA) services in network environments. It is an extension of the original TACACS protocol and is often employed to control access to network devices and services.

The Security+ exam may cover topics related to network security, access control, and authentication protocols. Understanding TACACS+ and its role in providing AAA services, especially in the context of network device administration, can be relevant for exam preparation.
