AAA provides a cohesive framework to control who can access a router, what services they can use on a router, and what they can do on a router. The following sections cover the functions of AAA, as well as how to enable it. The authentication component of AAA is responsible for providing a method to identify authenticate users.
Authentication: Who are you?
The goal of this document is not to cover all AAA features, but to explain the main commands and provide some examples and guidelines. Failure to do so may result in misconfiguration and subsequent lockout. For more information on document conventions, see the Cisco Technical Tips Conventions. The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared default configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.
Open topic with navigation. AAA stands for authentication , authorization , and accounting. AAA is a framework for intelligently controlling access to computer resources, enforcing policies, auditing usage, and providing the information necessary to bill for services. These processes working in concert are important for effective network management and security. Authentication provides a method of identifying a user, typically by having the user enter a valid username and password before access to the network is granted. Authentication is based on each user having a unique set of login credentials for gaining network access.
What is AAA security? An introduction to authentication, authorisation and accounting by Brodie O'Carroll, Nov 27, Authentication, authorisation and accounting AAA refers to a common application security framework for mediating network and application access. AAA intelligently controls access to computer resources by enforcing strict access and auditing policies. This process ensures that access to network and software application resources can be restricted to specific, legitimate users. AAA security has a part to play in almost all the ways we access networks today.
