AAA

Definition

AAA stands for Authentication, Authorization, and Accounting. It is a framework used to control access to computer resources, enforce policies, and audit usage. Authentication verifies the identity of a user or system, Authorization determines what an authenticated user or system can do, and Accounting tracks the consumption of resources by users or systems.
