AAA:

Authentication, Authorization, and Accounting

aka. 3A

AAA refers to a framework used in network security and access control that encompasses three key components: Authentication, Authorization, and Accounting. Authentication is the process of verifying the identity of a user or device, ensuring that they are who they claim to be. This can involve various methods, such as passwords, biometrics, or security tokens. Once a user is authenticated, Authorization determines what resources or services the user is allowed to access, essentially granting permission based on predefined policies or roles.

Accounting, the third element of the AAA framework, involves tracking and recording user activities and resource usage within a system. This includes logging actions taken by users, which can be essential for compliance, auditing, and security monitoring. Together, these three components form a comprehensive approach to managing user access and maintaining security within information systems, especially in contexts like Security Operations Centers (SOC) where monitoring and compliance are critical.
