HWTACAS Server VS RADIUS Server

Hi,

Compared with RADIUS, HWTACACS is more reliable in transmission and encryption and is a better means of security control. 

The following table shows the main comparisons between the two.

I hope this helps.

Hi LilStylez237!

TACACS+
Terminal Access Controller Access Control System (TACACS+) is Cisco proprietary protocol which is used for the communication of the Cisco client and Cisco ACS server. It uses TCP port number 49 which makes it reliable.

RADIUS –
Remote Access Dial In User Service (RADIUS) is an open standard protocol used for the communication between any vendor AAA client and ACS server. If one of the client or server is from any other vendor (other than Cisco) then we have to use RADIUS. It uses port number 1812 for authentication and authorization and 1813 for accounting.
