CCIE Network Engineer:Three basic components of AAA certification

CCIE Network Engineer

AAA is the abbreviation of Authentication, Authorization, and Accounting. It is a security management mechanism for access control in network security. It provides three security services: authentication, authorization, and accounting. An architecture that provides security devices to authorize users to access devices or nearby networks. The authorization feature is used to limit the user’s authority after the user is authenticated. Statistics are used to maintain a log of device activity and behavior in the network or network devices.

AAA can perform its functions on the basis of a single user or a single service. In other words, it can be used for authentication

And authorize a single user or service, AAA is set on the router or PIX or any other such device, these

All devices require AAA to restrict users who access the device itself or the network connected to the device. The router can use the local database to obtain data for AAA, such as the user name or password or each user’s access control list; it can also request an authentication server through protocols such as RADIUS or TACACS+.

The three basic components of AAA:

Authentication (Authentication): is to verify the identity of the user to determine whether it is a legitimate user. To put it simply, to judge who you are? What do you have? What is your username and password? Authentication usually adopts the user to input the user name and password to conduct the authority review. The AAA server checks the user’s standards with each user in the database.

Authorization (Authorization): It is to authorize users to use which services they can use. Authorization clarifies how much authority an authenticated user can have, what he can do, and what data and information he can access. The authorization process is a combination of a series of coercive strategies, including: determining the type or quality of activities, resources, or what services are allowed by the user.

Accounting (Accounting): is to record the resources of users using network services, these information will be used as the basis for billing. The audit is a good record of who is on the network, who is doing what, and when. The audit process can be performed based on statistical logs, user information, authorization control, billing, trend analysis, resource utilization, and capacity planning activities of the connection process.
