Authorization is a method of providing certain privileges or rights to remote users for services requested. It’s likely that you are going to see EXEC authorization, where one user is allowed access to an EXEC shell and another is allowed access to a privilege shell. This can be configured for a group that a user belongs to, or it can be configured on an individual user basis, depending on your goal. User authorization overrides group authorization. Authorization can be configured locally in some cases or kept on a remote AAA server.
ACS SE can be accessed only through the serial console (before/after installation) and web interface (after installation). Running only the required components necessary to run ACS SE increases the security posture of the device. html Both platforms are identical in terms of functionality. exe database utility are available only on ACS for Windows. 78.

4. The AAA client sends a CONTINUE packet to the TACACS+ server with the username provided by the user. 5. The TACACS+ server then sends the REPLY packet back to the AAA client to ask the client to get the password. 6. The AAA client sends a CONTINUE packet to the TACACS+ server with the password provided by the user. 7. The TACACS+ server then sends the REPLY packet back to the AAA client to indicate a pass or fail of authentication. 1. The AAA client receives the connection request from the user.
