The CIA Triad & AAA

Page 2 of 2

The AAA Framework

While CIA defines what we protect, AAA defines how we manage access.

  • Authentication (Who are you?): Verifying a user's identity (Passwords, Biometrics, MFA).
  • Authorization (What can you do?): Determining the permissions a verified user has (Read-only, Admin access).
  • Accounting (What did you do?): Tracking user activities and logging events for auditing purposes. This ensures non-repudiation.
