• Methods include passwords, biometrics, and multi-factor authentication to enhance security.

Authorization

• Authorization determines what an authenticated user can do, specifying their permissions and access levels.
• This is crucial for implementing the principle of least privilege within an organization.

Accounting

• Accounting captures user activities and resource usage, providing analytics for compliance and auditing.
• This component allows organizations to track who accessed what information and when, assisting in security monitoring.

Benefits of AAA Framework

• Utilizing the AAA framework improves security by controlling and documenting user access meticulously.
• It enhances overall network security posture by identifying and mitigating potential vulnerabilities efficiently.
