Explanation
AAA offers different solutions that provide access control to network devices. The following services are included within its modular architectural framework:
+ Authentication - The process of validating users based on their identity and predetermined credentials, such as passwords and other mechanisms like digital certificates. Authentication controls access by requiring valid user credentials, which are typically a username and password. With RADIUS, the ASA supports PAP, CHAP, MS-CHAP1, MS-CHAP2, that means Authentication supports encryption.
+ Authorization - The method by which a network device assembles a set of attributes that regulates what tasks the user is authorized to perform. These attributes are measured against a user database. The results are returned to the network device to determine the user's qualifications and restrictions. This database can be located locally on Cisco ASA or it can be hosted on a RADIUS or Terminal Access Controller Access-Control System Plus (TACACS+) server. In summary, Authorization controls access per user after users authenticate.
+ Accounting - The process of gathering and sending user information to an AAA server used to track login times (when the user logged in and logged off) and the services that users access. This information can be used for billing, auditing, and reporting purposes.
