The architecture for AAA requires the following three components: This image shows a typical AAA architecture consisting of the three aforementioned components. Once the supplicant sends the username and password, the authenticator forwards the authentication credentials to the authentication server to verify that they match what is contained within the user database. This process is mainly used so that network and software application resources are accessible to some specific and legitimate users. Network and system administrators are responsible for monitoring, adding, and deleting authorised users from a system. The authentication portion of the AAA framework is the part where we can prove that we are who we say we are.

However, in many cases, the back-end database the AAA server uses to verify credentials and access levels is Microsoft AD. The port numbers in the range from 0 to 1023 (0 to 2 10 1) are the well-known ports or system ports. Usually, authorization occurs within the context of authentication. The RADIUS servers can also proxy authentication requests to other RADIUS servers or other types of authentication servers. The TACACS+ protocol's primary goal is to supply complete AAA support for managing multiple network devices. Computer Network | AAA (Authentication, Authorization and Accounting), AAA (Authentication, Authorization and Accounting) configuration (locally), Difference between Authentication and Authorization, Difference between Cloud Accounting and Desktop Accounting, Difference between single-factor authentication and multi-factor authentication, Domain based Message Authentication, Reporting and Conformance (DMARC), Challenge Handshake Authentication Protocol (CHAP).
