What does TACACS stand for?

TACACS stands for Terminal Access Controllers Access Control System. This term refers to a protocol that is used for remote authentication and accounting services. TACACS+ is the more modern and secure iteration of TACACS, which provides improved security through the use of encryption for the payload and provides various other functionalities compared to its predecessors.

This protocol is particularly relevant in network security contexts, where it facilitates the management of user credentials and access permissions for network devices. The importance of TACACS in managing remote access authentication lies in its ability to centralize user account management and enforce access policies efficiently.

The other options do not accurately represent the full name or purpose of TACACS, which is why they do not fit the correct definition of the acronym. Understanding TACACS and its role in network security can help professionals in implementing effective access control measures.
