RADIUS, an acronym for Remote Authentication Dial-In User Service, is the paradigm of AAA protocol. Originally developed in 1991 by Livingston Enterprises for the PortMaster series of its Network Access Servers (NAS), it later became an RFC standard through the Internet Engineering Task Force IETF:
Without going into too much detail, we will use RADIUS as an example to describe a common AAA architecture such as those used by an internet provider or ISP. In these architectures there is an intermediate element, the Network Access Server (NAS) that functions as a RADIUS client. The client is responsible for passing user information to the RADIUS servers and then acting on the response that is returned.
The RADIUS servers receive the request from the client and authenticate the user based on the data received (usually against directory servers) returning the configuration with the necessary information for the client to access the authenticated user’s service. During this Authentication and Authorization process that verifies the validity of the user and the resources to which he/she has authorized access. This management is complemented by the Posting process that will record the relevant data of the session and is normally used to generate pricing records.

To maximize the value of an IAS-based RADIUS infrastructure, an organization-wide decision must be made to use centralized services for network access management. This includes using a centralized account database, such as the Active Directory® directory service, and centralizing the administration of network access policies on IAS servers. Centralized administration greatly reduces the costs associated with maintaining network access control information on distributed network access equipment. In addition, leveraging centralized network access policies and accounts helps reduce the security risks associated with configuring and managing distributed equipment.
To maximize your IAS investment and minimize future IAS infrastructure changes, you should evaluate each of these scenarios with respect to your organization. Although IAS is only used in this solution for wireless network access, this solution can be extended to support each of these scenarios. Chapter 3, Solution Architecture for a Secure Wireless LAN, provides additional information about extending the RADIUS infrastructure to support additional scenarios.
When configuring a device to support multiple authentication methods, you can prioritize the order in which the device tries the different methods. This topic discusses how authentication ordering works and how to configure it on a device.
If an authentication method included in the statement is not available or if the authentication method is available, but the corresponding authentication server returns a deny response, it tries the next authentication method included in the authentication-orderJunos OSauthentication-order statement.

In summary, TACACS+ is more secure than RADIUS. However, RADIUS has better performance and is more interoperable. RADIUS is widely supported, while TACACS+ is a Cisco proprietary product and is not widely supported outside of Cisco.
