In network security, AAA stands for Authentication, Authorization, and Accounting. This framework is essential for managing access to network resources.

- **Authentication** involves verifying the identity of a user or device. This can be achieved through various methods, such as passwords, biometrics, or digital certificates. By ensuring that users are who they claim to be, organizations can prevent unauthorized access to sensitive resources.

- **Authorization** follows successful authentication and determines what an authenticated user or device is permitted to do. This includes defining user roles and permissions, so individuals only have access to the resources necessary for their duties. This principle of least privilege helps minimize the potential for misuse of resources.

- **Accounting** refers to tracking user activities on the network. This involves logging and auditing user actions, such as the resources accessed and the time spent on various activities. Accounting helps in maintaining compliance with policies and regulations, as well as in troubleshooting security incidents.

This comprehensive approach ensures that a network is secure by not only confirming identities but also managing what those identities can access and keeping records of their activities. The other options do not correctly encompass the complete and established components of the AAA framework as recognized in the field of network security.
