What is the term for monitoring user behavior within an AAA framework?

The correct term for monitoring user behavior within an AAA (Authentication, Authorization, and Accounting) framework is accounting. Accounting refers to the processes used to track user activity and resource usage within a system. This includes logging details such as when a user logs in and out, what resources they access, and how much time they spend on the system. These logs are crucial for auditing and compliance, as they help organizations understand user behavior, enforce policies, and identify any irregular activities that could indicate security issues.

Authentication focuses on verifying the identity of a user or system, while authorization determines what resources and actions a verified user is allowed to access. An audit, while related to the assessment and evaluation of audit logs and compliance, does not specifically refer to the ongoing monitoring of user behavior that the accounting function embodies. Accounting encompasses these activities by providing a structured framework for documenting and analyzing user interactions within the system.
