Brute Force Attack

What is Brute Force Attack?

Brute force attacks systematically check all possible passwords or encryption keys until finding the correct one. While simple in concept, modern computing power makes them feasible against weak passwords. Variants include dictionary attacks (using common words), credential stuffing (using leaked password lists), and reverse brute force (trying one password against many accounts). Protection includes strong passwords, account lockout policies, rate limiting, CAPTCHA, and multi-factor authentication.
