Description: An AAA server is a server program that handles user requests for access to computer resources and, for an enterprise, provides authentication, authorization, and accounting (AAA) services. The AAA server typically interacts with network access and gateway servers and with databases and directories containing user information. The current standard by which devices or applications communicate with an AAA server is the Remote Authentication Dial-In User Service (RADIUS).

This video is a simple demo of bypassing AAA server. When a user want to log on the router, router sends the authentication information to AAA server. In video attacker performs arp poisoning and make the router feel that it has mac address of AAA server. Now every information send by router to AAA server will go to attacker's machine. if attacker machine drops the packet router will understand that AAA server is down.

Nice share. Thanks.
