What does the AAA framework stand for in network security?

1. Access, Authorization, Accounting

2. Authentication, Authorization, Accounting

3. Assessment, Authentication, Access

4. Authentication, Access, Assessment

The correct answer is: Authentication, Authorization, Accounting

The AAA framework in network security stands for Authentication, Authorization, and Accounting. This model is essential for managing and securing access to network resources. Authentication is the first step in this framework and involves verifying the identity of a user or device trying to access the network. This can be achieved through various methods, such as usernames and passwords, biometric scans, or security tokens. Authorization follows authentication and determines what an authenticated user has the right to do on the network. It involves setting permissions and access levels, ensuring users can only access resources that they are permitted to use. Lastly, Accounting refers to tracking user activity on the network, including logging access and changes made. This aspect is crucial for auditing and compliance purposes, as it helps organizations monitor how resources are used and identify any potential security breaches. Understanding the AAA framework is vital for securing networks and managing user access effectively, as it provides a structured approach to ensure that all access is controlled and monitored.
