AAA CONFIGURATION ON OMNIACCESS 5740 USG
The OmniAccess 5740 USG is targeted at the edge of enterprises that have a
good deal of valuable data in their networks.
It is important to ensure that the customer has knowledge and control over the
following: Who can access, manage or use the system? What these users are
allowed to do to the system, or through the system? What was done to the system
by these users? Where the above information is stored or retrieved from?
AAA (Authentication, Authorization, and Accounting) is a system in IP-based
networking to control the resources that users have access to and to keep track of
the user activity over a network.
• Authentication is the process of identifying an individual, usually based on a user
name and password. Authentication is based on the idea that each individual user
will have some unique information, that sets the user apart from others.
• Authorization is the process of granting or denying a user access to network
resources once the user has been authenticated. The amount of information and
the type of services the user has access to depends on the user's authorization
level.
• Accounting is the process of keeping track of a user's activity while accessing the
network resources including the amount of time spent in the network, the services
accessed and the amount of data transferred during the session. Accounting data
is used for trend analysis, capacity planning, billing, auditing, and cost allocation.
AAA services often require a server that is dedicated to providing these three
services. RADIUS, DIAMETER, TACACS, and TACACS+ are some often used
AAA protocols.
