RADIUS Overview

308640-15.1 Rev 00

1-7

SecurID, a token-passing security feature developed by Security Dynamics, Inc.,

prohibits unauthorized users from accessing a RADIUS client through a router

management application (Telnet, HTTP, FTP, or the Technician Interface). A

RADIUS client configured with SecurID communicates with a centrally located

ACE/Server to identify and authenticate authorized users.

SecurID offers a more advanced level of authentication because it requires two

security checks instead of one. To access the protected router, you must enter a

valid SecurID PASSCODE, which consists of:

• A secret, memorized personal identification number (PIN)

• The current token code, generated by your assigned SecurID card. The token

code appears in the liquid crystal display (LCD) of the SecurID card. The

code changes at a specified interval, typically 60 seconds.

The combination of the PIN and the token code ensures exceptionally secure user

authentication and access control.

Each user authorized to access a RADIUS client configured with SecurID must

have an electronic SecurID card issued by Security Dynamics, Inc. Security

Dynamics programs each card with a PIN to uniquely identify its prospective

owner, and then assigns the card for exclusive use to that person only.

Using RADIUS with Multilevel Access to the Router

System administrators and network operators can use RADIUS authentication

services from a console connected to the router. This feature, which is part of

Nortel Networks multilevel access, grants authenticated users access to the router

for configuration and monitoring purposes. Nortel Networks recommends that

you use the BCC to configure multilevel access.

Multilevel access also assigns a privilege level that determines which system

commands the user can execute. For more information, see Appendix A in Using

the Bay Command Console (BCC).
