AAA - Authentication, Authorization, and Accounting,

🔒 Demystifying AAA Concepts, Protocols, and Differentiations Explains the AAA model, which stands for Authentication, Authorization, and Accounting, as a centralized system for managing user access to network devices such as Cisco Routers and Switches. Authentication focuses on verifying a user’s identity through credentials, while Authorization determines what actions or resources that user is permitted to access after identity verification. Accounting tracks the resources consumed by the user, recording session statistics and usage information for purposes like troubleshooting and billing. The text also contrasts the two main protocols used to implement AAA services, TACACS+ and RADIUS, noting that TACACS+ is a Cisco proprietary protocol that uses TCP and separates the AAA functions, while RADIUS is an open protocol that uses UDP and combines authentication and authorization. Ultimately, AAA provides flexibility and scalability in managing both device administration and general network access.
