What does TACACS stand for?

Terminal Access Control Access-Control System
Terminal Authentication Control Access System
Technical Access Controller Access-System
Text Access Control for Accessing Systems

The correct answer is: Terminal Access Control Access-Control System

TACACS stands for Terminal Access Control Access-Control System. This protocol is primarily used for network device access control and provides authentication, authorization, and accounting services. TACACS allows administrators to centralize control of user access to network resources, making it easier to manage permissions and ensure security. The other options do not accurately reflect the functions or the terminology associated with TACACS. For example, Terminal Authentication Control Access System suggests a focus only on authentication and does not encompass the broader control aspects that TACACS provides. Similarly, Technical Access Controller Access-System and Text Access Control for Accessing Systems do not represent the original intent or the capabilities that TACACS is designed to offer. Therefore, the first choice is the correct understanding of what TACACS represents in network access management.
