AAA (Authentication, Authorization, and Accounting) is a framework used to secure network access and track user activity.

🔹 Key Concepts:

1️⃣ Authentication

Verifies the identity of users or devices before granting access.

Example: Username/password, digital certificates, or MFA.

2️⃣ Authorization

Determines what resources and actions a verified user is allowed to perform.

Example: Admin vs. read-only access.

3️⃣ Accounting

Tracks user activity for auditing, billing, or compliance.

Example: Logging commands entered on a router or switch, session duration, or data usage.

⚡ Key Point:
AAA ensures secure access, controlled permissions, and accountability, which are critical for network security and management.
