What does AAA mean in NETWORKING

AAA stands for Authentication, Authorization, and Accounting. It is a system of protocols and services used in corporate environments to regulate user access while also tracking and documenting user activity on the network.

By using AAA protocols, network administrators can accurately manage user access privileges across the corporate environment while keeping an audit trail of user activities on the network. This helps ensure secure access control while bringing visibility into how users interact with various systems.

The authentication component validates users by confirming their identities through passwords or digital certificates before granting them access privileges. The authorization component assigns specific levels of access rights that determine what users can do on the network. Finally, the accounting component tracks activities performed by users on the network such as file transfers or website visits.

A wide range of networks from small offices to large enterprises can benefit from deploying AAA protocols across their environments. In addition to local-area (LANs) and wide-area (WANs), even wireless networks can also be secured via AAA protocols.

RADIUS (Remote Authentication Dial-In User Service) is primarily responsible for providing authentication within the framework of AAA protocols. RADIUS typically works in conjunction with a variety of other authentication methods including one-time passwords, biometrics or smart cards to provide secure authentication services.
