One of the most important issues in traditional and modern networks architecture is security. Data integrity and authenticity are the most critical points that a network security model should protect and ensure. Authentication, Authorization and Accounting model (AAA Protocol) is one of the most portable security concepts. Authentication acts providing proof of authenticity for stored data and verifying proof of authenticity for received. Authorization acts providing privileges to those clients that present specific credentials. Accounting acts collecting accounting metrics for two reasons; to forward them to the billing server for billing results, and to keep them saved locally for the procedure of trend analysis.
