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.
