Configuring AAA

Authentication determines who the user is and whether that user should be allowed access to the network

or a particular device. It allows network administrators to bar intruders from their networks. It may use

a simple database of users and passwords. It can also use one-time passwords.

Authorization determines what the user is allowed to do. It allows network managers to limit which

network services are available to different users.

Accounting tracks what users did and when they did it. It can be used for an audit trail or for billing for

connection time or resources used (bytes transferred).

Collectively, authentication, authorization, and accounting are sometimes referred to as AAA. Central

management of AAA means the information is in a single, centralized, secure database, which is much

easier to administer than information distributed across numerous devices.

In the CDS network, login authentication and authorization are used to control user access and

configuration rights to the CDSM, SEs, and SRs. There are two levels of login authentication and

authorization:

• Device

• CDSM

In a CDS network, user accounts can be created for access to the CDSM and, independently, for access

to the SEs and SRs that are registered to the CDSM.

This section covers login authentication and authorization for the CDSM. For information about device
