AAA stands for?

AAA stands for?

• A. Advanced Authentication and Accounting
• B. Authentication, Authorization, and Accounting
• C. Authentication, Access, and Audit
• D. Authorization, Access, and Administration

Answer: (B)

AAA refers to the trio of security functions used to manage identity and access: Authentication, Authorization, and Accounting. Authentication verifies who you are, typically through credentials. Authorization determines what resources or actions you’re allowed to access once identified. Accounting records the activity for auditing and billing, capturing usage data over time. This combination is the standard terminology in many security and network systems. The other options don’t fit because they replace one or more established terms with nonstandard ones: Advanced instead of Authentication, Access in place of Authorization, Audit instead of Accounting, or Administration instead of Accounting.
