Radius vs tacacs+

First option is unnecessary work every time you need to grant/revoke access, update a user's password, etc. - you have to touch every single device in your network. Second option is just a bad practice in terms of security, plain and simple. Basic RADIUS or TACACS (i.e. nothing more than user authentication) is fairly simple to set up.

Cisco’s Identity Services Engine (ISE) is a powerful platform that reinforces security. It lets administrators control who and what connects to the network. ISE combines multiple applications and services into a single solution. With its configuration, ISE provides in-depth control, applying different levels of privilege based on user roles. Cisco extended the TACACS definition by adding security features and the option to split the AAA server into three separate servers; this new definition was called TACACS+. Although the TACACS+ and RADIUS protocols provide similar functionality, they have several key differences, such as the transport mechanism (UDP, TCP), performance impact ... TACACS. TACACS is defined in RFC 8907 (older RFC 1492), and uses (either TCP or UDP) port 49 by default. TACACS allows a client to accept a username and password and send a query to a TACACS authentication server, sometimes called a TACACS daemon. It determines whether to accept or deny the authentication request and sends a response back. 이 문서에서는 TACACS+와 RADIUS의 차이점에 대해 설명하므로 정보에 근거한 선택을 할 수 있습니다.
