ABSTRACT
Got the telecommuter, mobile workforce, VPN, multi-platform, dial-in user authentication blues? Need
a centralized method for controlling and auditing external accesses to your network? Then RADIUS,
TACACS, or DIAMETER may be just what you have been looking for. Flexible, inexpensive, and easy to
implement, these centralized authentication servers improve remote access security and reduce the time
and effort required to manage remote access server (RAS) clients.
